Machine learning stems from the concept that machines must be capable of learning and adapting by experience. AI refers to an overall concept that machines can perform the tasks smartly.

Machine learning and artificial intelligence are aiding companies and individuals to reach their goals, gain useful insights, make crucial decisions, and produce innovative, exciting and creative goods and services.

Q11. What are the types of machine learning?

Machine Learning is typically divided into three main types:

  1. Supervised Learning: The concept of supervised learning refers to a kind of Machine learning where the machine requires external supervision to learn from the data. The models that are supervised are trained by using the dataset that is labeled. Regression and Classification are the two primary issues which can be solved using Supervised Machine Learning.
  2. Unsupervised Learning: Unsupervised Learning is a kind of machine learning where the machine doesn’t require any supervision from outside to learn from data, hence the term unsupervised learning. Unsupervised models are trained with the data that is not labeled. They are employed for solving the Association and Clustering problems.
  3. Reinforcement learning: When learning through reinforcement the agent interacts with its environment through the production of actions, and then learns by receiving feedback. Feedback is provided by an agent by way of rewards. For each positive act, he receives the reward of a positive one, and for each negative action the agent receives an unfavorable reward. There is no oversight given for the agents. Q-Learning algorithm is utilized to enhance reinforcement.

Q12. What is TensorFlow and why is it used?

TensorFlow is an open source library created by Google mostly in order to facilitate advanced applications in deep-learning. It also can be used to support the traditional methods of machine learning. TensorFlow was initially designed for massive numerical computations, without the concept of deep learning in mind. It was initially created by Google Brain Team for use in neural networks and machine learning research. It is utilized for data-flow programming.

It is a vast toolbox that has flexible libraries, community and resources which allow researchers to advance the technology of ML and developers quickly create and implement ML powered apps.

Q13. What do you understand about statistical AI and classical AI?

Statistical AI: Statistics-based Artificial Intelligence (StarAI) is a combination of logic AI and probabilistic AI. Relational AI is very effective in dealing with complex domains that require numerous and sometimes even a diverse amount of entities linked by complicated relationships, whereas statistical AI is able to handle. 

The theory of statistical learning is an algorithm for machine learning that is based on the field of statistics as well as functional analysis. It focuses on identifying an appropriate predictive function that is based on the information provided. The principal idea of the statistical learning theory is to create an algorithm that draws conclusions from the data and creates predictions.

Classical AI: Symbolic AI is also called classical AI is the area of research in artificial intelligence that aims to represent humans knowledge and experience in an explicit manner. Statistics methods should be considered to be an integral component of AI systems beginning with the formulation of research questions, through the creation of the research plan and the subsequent analysis, all the way up until the analysis of results. 

Performance is limited areas, which are often extremely restricted that are composed of particular problem circumstances or microworlds. The performance of SHRDLU is shattered when faced with an expression it’s not specifically programmed to handle.

Q14. What are the important languages used in AI?

  • C++
  • R

Q15. What is Artificial Neural Network and name some of the uses?

Artificial neural networks (ANNs) typically known as neural networks (NNs) are computer systems that are influenced by the neural networks in nature that make up animal brains. An ANN is built on an array of nodes or units that are connected. They are known as artificial neurons, which are a loose representation of the neurons that make up the human brain.

Artificial Neural Networks are used to assist in verification of signatures. ANN have been trained to discern the difference between authentic and fake signatures. They can be used to aid in the verification of authentic and digital signatures. In order to train the ANN model, a variety of datasets are fed into the database.

Artificial Neural Networks work in an identical way to that of their biological counterparts. They could be described as directed graphs with weighted weights in which neurons can be compared with the nodes and the relationship between two neurons can be described as edge weighted. The creation of Artificial neural networks wouldn’t be possible without math to describe how neurons actually function.

They’re great tools to identify patterns that are extremely complex or multiple for humans to comprehend and train machines to detect.

The most commonly utilized ones include:

  • Feed Forward Neural Nets
  • Multiple Layered Perceptron Neural Nets
  • Convolution Neural Nets
  • Recurrent Neural Nets

Q17. In your view, what is the future of artificial intelligence?

Artificial Intelligence has affected many human beings and virtually every sector, and is expected to continue impact the world in a variety of ways. Artificial Intelligence is the driving force behind the development of technologies such as the Internet of Things, big data and robotics.

AI can make use of a huge quantity of data and make an ideal decision in a short amount of time that is nearly impossible for humans. AI is leading in areas which are vital to mankind like research into cancer and cutting-edge climate change technology such as smart cars, smart vehicles, as well as space exploration.

AI has occupied the central stage of development and innovation of computing and will not be leaving the stage in the near future. Artificial Intelligence will affect the world like nothing else ever before.

Q18. What is Q-Learning?

The Q-learning algorithm is an off-policy reinforcement learning algorithm that aims to determine the most effective decision to take based on the present situation. It’s considered to be off-policy since the Q-learning algorithm learns from actions not covered by the current policy, for example, taking random actions so it isn’t required to have a policy. 

Q-learning is an approach based on value that is providing information that informs the actions an agent needs to do. Let’s look at this technique through an example: five rooms in the building that are linked via doors.

Q-learning is an off-policy, model-free reinforcement learning method that determines the most efficient strategy for action, based on the present situation of the actor. Based on the location of the agent in the surroundings it will determine the next step to be performed.

It’s employed to determine the most effective decision-making policy by employing a Q-function. The goal is to maximize the value of Q function. The Q table allows us to determine the most effective solution for every state.

Q19. Explain Markov’s Decision Process.

In math the term “markov decision process” refers to a discrete-time stochastic controlling process. It is a mathematical framework to describe decision making in scenarios where the outcomes are largely random, and are also subject to the control of the decision maker. 

MDP facilitates formalization of sequential decision making, where the actions of a state don’t only affect the immediate reward, but as well the future state. It’s a great framework to analyze problems and will maximize the long-term returns through the use of sequences of decisions.

In this case, an agent is expected to choose the best option in light of his current situation. If this process occurs repeatedly, then the situation is called the Markov Decision Process. The Markov Decision Process (MDP) model consists of an array of possibilities for global states. Four fundamental elements are required to depict what is known as the Markov Decision Process:

  • The set of states that are finite.
  • A set of finite actions
  • Rewards
  • Policy P a

In this case the agent executes an action A that causes an action to shift from state S1 to state S2 and from beginning state to the state that is the end in which case, during these actions, the agent earns certain rewards. The sequence of actions undertaken by the agent could be defined as the police.

Q20. What is ANN? Explain in detail.

Artificial Neural Network (ANN) is a computational model based upon the Brain Neural Network (BNN). Human brains contain billions of neurons that gather information, process it and generate meaningful outcomes from it. 

The neurons make use of electrochemical signals to communicate and transmit the information on to other neurons. Similar to that, ANN consists of artificial neurons known as nodes that are linked to other nodes that form a complex connection between the output as well as the input.

Three layers are present to artificial neural networks:

  • Input Layer: The input layer is composed of neurons that process information from outside sources such as data sets, files images, videos as well as sensors. This component of the Neural Network does not perform any kind of computation. It simply transfers data from outside into the Neural Network
  • Hidden Layer: The hidden layer collects the information of the input layer and utilizes it to draw conclusions and build a variety of Machine Learning models. The layer is further subdivided into layers that collect features, make decisions and connect to different sources and anticipate future actions based upon the incidents that occurred.
  • Output layer: Following processing the data, it’s transferred onto the output layer to be used for transfer to the outside environment.

Q21. What is deep learning and how is it related to artificial intelligence?

The concept of deep learning is an aspect of machine learning. It is the process of using multi-layered neural networks that process data in ever more sophisticated ways, allowing the software to improve its ability to complete tasks such as speech or image recognition, through exposure to the vast amount of data to continue improving in its ability to detect and process data. 

Neural networks with layers that are stacked over each other to make use of deep learning are referred to as deep neural networks. The concept of deep learning is an aspect of AI which is a broad term that refers to any computer program that performs something intelligent. That is every machine learning program is AI but there are exceptions to the rule that AI is machine-learning, and so on.

The capability to process large amounts of elements makes deep learning extremely effective when working with data that is not structured. However deep learning algorithms could be too complex for simpler issues because they need access to a huge quantity of data in order to be efficient. 

One of the primary benefits of deep learning is the ability to tackle complicated problems that require the discovery of patterns hidden in the data or an understanding of the intricate relationships among a variety of connected variables.

Q22. Explain alternate, compound, artificial and natural keys.

1. Alternate Key: Excluding primary keys every candidate key is referred to in the field of Alternate Keys.

2. Compound Key: If there isn’t a one data element that determines the location within the construct, then combining various elements to provide an unique identifier for the particular construct is referred to by the term Compound Key.

3. Artificial Key: When there is no clear key that stands on its own or if a compound is accessible, then the final option is to simply make a key by assigning a unique number to every record or event. This is called an artificial key.

4. Natural Key: A natural Key is an element of data that are stored in a structure and is used to serve as the key.

Q23. How would you explain Machine learning to a non-technical person?

ML is focused on patterns that can be identified. One great example can be seen in your Facebook newsfeed as well as Netflix’s recommendation engine.

In this situation, ML algorithms observe patterns and can learn from the patterns they observe and then apply these to their own. When you implement an ML program it will be learning and growing with every attempt.

If the interviewer prompts you to give more concrete examples, you could provide the following examples:

  • Amazon product suggestions
  • Fraud detection
  • Ranking of search results
  • Spam detection
  • Spell correction

Q24. How do you describe the Tower of Hanoi?

Tower of Hanoi is an abstract mathematical puzzle, which comprises 3 towers (pegs) and more than one ring. The rings are of various dimensions and are stacked in an ascending order i.e. the smaller one is stacked on top of the larger. The Tower of Hanoi is also utilized to create a backup rotation technique when carrying out backups of computer data where several media or tapes include. 

Tower of Hanoi consists of three pegs, or towers, with N disks, placed one on top of one. The purpose of the game is moving the tower from one peg to the next peg using these simple rules. One disk is only able to be moved at any one time. 

The larger disk cannot be placed over that smaller one. It is believed that the Towers of Hanoi and London are thought to measure executive functions like working memory and planning. Both have been utilized as an attempt to assess frontal lobe functions.

The Tower of Hanoi can be solved by using an algorithm that uses a decision tree and broad-first search (BFS) algorithm used in AI. With three disks, a puzzle can be completed in seven moves. The minimum amount of moves needed to complete the tower of Hanoi puzzle is 2 n – 1. Where there is a number n, which is the amount of disks.

Q25. How machine learning, artificial intelligence and deep learning differ from each other?

1. Artificial Intelligence is the broad field of computer science that aims to develop machines that are capable of being like human beings. Examples: Robotics

2. Machine learning is a part of AI. It’s the method of allowing machines to take decisions without programming. It’s a way of creating machines that can learn through data to tackle issues. Examples include churn prediction, detection of diseases, and text classification.

3. Deep Learning is the subset of Machine Learning. It uses neural networks which can conduct unsupervised learning using unstructured data. They learn by representation learning. It can be supervised, unsupervised, or semi-supervised. Deep learning seeks to construct neural networks that automatically recognize patterns to identify features. Examples include uncrewed vehicles and how they detect stop signs along the road.

Q26. What are the misbeliefs about artificial intelligence?

There are a few myths regarding Artificial Intelligence that exists are:

  • Machines learn from themselves: The truth is quite different from the assertion. Machines aren’t yet at a point where they are able to make the decision for themselves. Machines learn by using a process known as machine learning. It allows machines to grow and learn by analyzing their own experiences, without needing to be programmed. Machine learning involves the development of computers that connect to data and learn by themselves.
  • Artificial Intelligence (HTML0) is basically the same in concept as Machine learning. Machine Learning differs from one the other. Artificial Intelligence concerns itself with the creation of devices that mimic human intelligence. Machine learning is an aspect of artificial intelligence that is concerned with creating programs that analyze data, make sense of it, and make decisions.
  • Artificial Intelligence could replace humans. There is a chance AI’s capabilities could match or exceed human capabilities in the near-term. However, the idea that AI could take over humans is merely a piece of fiction. AI is meant to enhance humans’ intelligence and abilities, but not slave it.

Q27. What is the working of deep learning?

  • Deep Learning is based on the fundamental part of a brain called a brain cell, also known as a neuron. Based on a neuron, an artificial neuron, also known as a perceptron was invented.
  • Dendrites in a neuron are the ones that exist in nature, which receive inputs.
  • A perceptron also receives several inputs, performs various functions and transformations and produces an output.
  • Similar to how the brain has many connected neurons, referred to as neural networks, we could also create artificial neurons called perceptrons that make up the Deep neural network.
  • An Artificial Neuron or Perceptron models a neuron, which is equipped with a variety of sensors, all that is assigned a certain weight. The neuron is then able to compute a function based on these inputs that are weighted and produce the output.

Q28. What is reward maximization?

The term reward maximization is utilized to describe reinforcement learning, that is the goal of the agent that learns reinforcement. In RL the term “reward” refers to a positive feedback that is earned by taking actions to transition from one state to the next.

If an agent takes an action that is good, by applying the best policies, he will receive an award, but if the agent performs an unsatisfactory action and the reward is subtracted, the other reward will be deducted.

The aim of the person who is in charge is to maximize the rewards through applying optimal policy, also called reward maximization.

Q29. How will you choose an algorithm for your problem?

To resolve a problem it is possible to use multiple machine Learning algorithms with various approaches and limitations. However, a common method can be used to solve many problems, and you can choose the right algorithm. Here are the steps to take into consideration when choosing an algorithm:

Classify the Issue: The first step is to find the algorithm that will classify it according to the type of input that you have and the results you’d like from it. If your data has been labeled, then it’s an issue with the supervised learning. If the data aren’t marked, then it’s an unsupervised learning issue. In the end, if the aim of the problem is to optimize an existing model, it’s a reinforcement-learning problem.

In the same way it is possible to categorize problems according to the outcome you would like to get using the method. If the outcome is expected to be numerical, the problem is considered to be a regression. If class is the result of the model, then it’s a classification challenge and grouping of input data can be classified as clustering issues.

Understanding the data: Data is a crucial factor in determining the best algorithm to tackle your issue. This is due to the fact that certain algorithms are capable of processing huge amounts of data, whereas others prefer smaller samples. The process of analyzing and changing your data can aid in identifying the limitations and challenges you’ll have to overcome when working on the issue.

.

Locate the accessible Algorithms: Determine the algorithms that you can use to solve the issue within an appropriate time frame. A few of the variables that could influence your selection of the best algorithm are the efficiency that the method is able to achieve, its complexity and scalability, understanding, build and learning time and space, as well as the amount of time needed to resolve the issue.

Apply the Algorithm: Once you have selected an algorithm to use, you will need to create an evaluation criteria by carefully selecting the test value and subgroups in the data. Additionally, look at the time it takes each algorithm to resolve the issue. The algorithm that gives precise results within the specified time, while taking smaller amounts of space, will be the ideal algorithm to solve your problem.

Q30. What do you understand about image recognition systems?

Image recognition, within the context of machine vision, is the capability of software to detect things, places, people writing, and other actions in pictures. Computers are able to use machine vision technologies with cameras or artificial intelligence programs in order to achieve recognition of images. 

Google lens is among the instances of applications that recognize images. This particular technology is utilized by retailers because they are able to perceive the image’s context and provide accurate and personalized results for users based on their interests and actions.

Effective AI image recognition program does not just decode images, but also has the ability to predict. Applications and software that have been specifically trained to interpret images are able to recognize places, people writing, objects and other actions that are in the pictures or videos.

Q31. What’s a Turing test and who is the father of the Turing machine?

The Turing Test is a very simple way to determine the degree to which a machine has demonstrated human intelligence. If a machine is able to have an exchange with a person and not be recognized as an actual machine, it has proven human intelligence. 

“The Turing Test is an essential tool to combat this danger. It is essential to comprehend how real-time, online communication such as this can affect individuals to the point that they fall for believing something is real even though it’s not.”

The Turing Test comes with many benefits. By using human beings to evaluate human intelligence, it is possible to be sure that judges will be excellent humans who are intelligent. Additionally in the event that controls are properly implemented in addition to ensuring that the third participant is appropriately hidden and accounted for, the test removes any chance of biased judgment. 

Many consider Alan Turing to be the founder of computer science today, Alan Turing was famous for his contributions to the creation of his first computer, which decoded the code used by German Enigma machine during the Second World War as well as formulating a process known in the Turing Test, forming the foundation for Artificial Intelligence.

Q33. What is Reinforcement Learning and how does it work?

Reinforcement Learning is a form of Machine learning algorithm, that is based on a feedback loop in which an agent and the environment are installed.

The method of operation is that the agent is taught how to behave in the environment by performing certain actions , and taking note of the benefits and outcomes that are derived from those actions. Therefore, this method is a behavior-driven one and is based on reinforcements that are learned through trial and error.

Example: learning how to cycle. This technique is a great way to improve the efficiency of manufacturing, logistics for supply chain and robotics.

Q34. Which estimation is used to test the machine’s intelligence? Explain.

The Turing test can be used to establish if the machine is capable of thinking as humans. IT was invented through Alan Turing in 1950. The Turing Test is like an interrogation game played by three people. There is an interrogator that is human. He is required to question two other players – one computer and another human. 

The person being interrogated must identify which one is an actual computer, by asking him questions. The computer must try to be difficult to differentiate from humans. The computer will be deemed intelligent when it is unable to distinguish itself from humans.

Imagine the following scenario: The computer is Player A and Player B, on the other hand, the other player is the person who asks questions. The person being interrogated knows there is one computer However, he has to determine which one is which.

Because all users communicate using the keyboard and display this outcome isn’t affected by the ability of the machine to translate the words in speech. The result of the test is measured not by the quantity in correct responses, however, rather by how closely the answers resemble the human responses. The computer can take whatever action it needs to make the person being interrogated fake a name.

The question-answer session could be similar to this:

Interrogator: Are you a computer?

Player A (computer): No.

Interrogator: Multiply two huge numbers, such as (256896489*456725896).

Player A: After an extended period of time and a long delay, he provides the wrong answer.

If an interrogator fails to discern between a machine and a person in this game, then the computer is able to pass the test and is believed to be smart and capable of thinking as humans. This game is commonly referred to as an imitation game.

Q35. Explain the most commonly used neural networks.

Feedforward Neural Network

  • The most basic form of ANN is where input or data is transported in one direction.
  • The data is processed by the input nodes, and then exits at out nodes. The neural network could or might not contain the hidden layers.

Convolutional Neural Network

  • In this case, inputs are analyzed in batches as filters. This allows the network to keep the images in segments and also compute the operation.
  • Primarily used for image and signal processing.

Recurrent Neural Network(RNN) – Long Short Term Memory

  • It works by keeping an output from a layer, and returning it to the input in order to assist in predicting the results for the particular layer.
  • This is where you allow the neural network to perform front propagation and keep the details it requires for future use.
  • In this way, each neuron can remember some information that it was able to recall from the prior time-step.

Autoencoders

  • These are models of unsupervised learning that have an input layer, an output layer, and one or more layers hidden that connect them.
  • The output layer contains the same amount of input units. Its goal is to rebuild the inputs of its layer.
  • It is usually used for decreasing dimensionality as well as for the purpose of learning model-based generative models for data.

Q36. What is hyperparameter, parametric and non-parametric?

Hyperparameter: When it comes to machine learning, the hyperparameter is the parameter that decides and regulates the entire learning process. Examples of these parameters are learning Rate, Hidden Layers, hidden units, activation functions as well as others. These parameters are not part of the model. The choice of the right hyperparameters can improve the algorithm.

When it comes to machine learning, you can find two kinds of models: non-parametric and parametric. The parameters are the predictive variables used to create an algorithm for machine learning. The rationale behind the models can be found below:

Parametric Model: Parametric models make use of a predetermined number of parameters to build the model. It makes certain assumptions regarding the data. The examples of parametric models include Linear regression, Logistic Regression, Naive Bayes, Perceptron, etc.

Non-Parametric Model: Non-parametric modeling employs variables that are flexible. It takes into account some assumptions regarding the data. These models are suitable for more data with no prior knowledge. Examples of non-parametric models include Decision Tree, K-Nearest Neighbor, SVM with Gaussian kernels and many more.

Q37. What are breadth-first search, depth-first search, and bidirectional, iterative deepening depth first, uniform cost search algorithms?

Breadth-First Search Algorithm: The breadth-first-search (BFS) method, utilized to search graph or tree data structures, begins from the root node, and then moves through the neighboring nodes and finally, moves on to the next node. Once the structure is discovered the algorithm creates a single tree at any time. Because this task is possible to accomplish using the FIFO (first-in first-out) data structure, this technique provides the most efficient route to solution.

Depth-First Search Algorithm: Depth-first searches (DFS) is built on LIFO (last-in first-out). Recursion is implemented by LIFO, which is the LIFO stack structure of data. Therefore, the nodes are not in the same order from those in BFS. The path is saved at every iteration of root to leaf nodes , in an orderly fashion, in accordance with the space requirements.

Bi-directional Algorithm: In the bidirectional search algorithm the search starts with the initial state and reverses to the final state. The searchers meet to find an identical state. The initial state is connected to the state that is objective in a reverse manner. Each search is conducted up to a half of the total method.

Iterative Deepening Depth First Algo: The repeated search process of levels 1 and 2 occur in this type of search. The search continues until the answer is found. Nodes are created until the goal node is made. The nodes’ stack is stored.

Uniform Cost Search Algorithm: The search for uniform cost does sorting to increase the cost of a path to a particular node. It expands the cheapest node. It is the same as BFS when each iteration has the same price. It examines possible ways to reduce the growing cost structure

Q38. What is the importance of game theory in Artificial Intelligence?

Game theory, which was developed by American mathematician Josh Nash, is vital to AI as it plays a key function in how these clever algorithms are improved over time.

At its most fundamental, AI is about algorithms which are used to discover solutions to issues. Game theory concerns opposing players seeking to accomplish a specific goal. Because most of our lives are concerned with competition, game theory has many practical applications in real life.

These kinds of problems are typically dynamic. Some game theory problems are good possibilities to use AI algorithms. Thus, whenever game theory is employed to multiple AI agents who interact with one another won’t be concerned with utility to themselves.

Data scientists in this field must be cognizant of games like:

  • Symmetric contrasts with. Asymmetric
  • Perfect information vs. imperfect information
  • Cooperative against. non-cooperative
  • Simultaneous in comparison to. sequential
  • Zero-sum vs. non-zero-sum

Q39. What is Natural Language Processing?

Q40. What do you understand about computer vision in AI?

Computer Vision in the field of AI allows computer systems to make sense of images or any other stimulation and then take action according to the input. AI provides the system with the capability to think, and computer vision grants the system the ability to look. Computer vision is like human vision.

Pattern recognition is at the heart of modern computer vision algorithms. Computers are trained on vast amounts of visual information. Images are processed, items are identified and patterns are discovered within those objects. 

For instance, if you send a million images of flowering plants to computers, they will study them, discover patterns common to every flower species, and then create an image of a “flower” in the conclusion of that process. 

This means that every time we send them photos the computer will be capable of identifying precisely whether the image we submit is actually flowers. Computer vision is present in many aspects in our daily lives.

For instance: Content management such as the content organization system in Apple Photos, Facial Recognition systems, autonomous vehicles and augmented reality, for example. use computer vision.

Q41. Explain Exploitation and Exploration trade-off.

One of the most important concepts that is important in reinforcement learning exploration and exploration trade off.

Exploration, as its title suggests, is about finding out more about the environment. However Exploitation involves making use of the exploited data to increase the benefits.

  • Think about the tiger and the fox illustration, where the fox consumes only meat (small) chunks that are near him , but doesn’t consume the larger chunks of meat on top despite the fact that larger chunks of meat would earn him higher rewards.
  • If the fox focuses on the most lucrative reward, he’ll never be able to eat the large pieces of meat. This is known as exploiting.
  • If the fox chooses to go out and explore to find the greater reward i.e. the huge piece of meat. This is exploration.

Q42. What is a minimax algorithm with other terms?

Minimax algorithm refers to a backtracking technique used to make decisions within the field of game theory. The algorithm identifies the most effective strategies for a person by presuming that a player is also performing optimally.

The algorithm is based on two players. One of them is known as MAX and the other is known as MIN.

Terminologies used in the following terms are utilized to describe Minimax Algorithm: Minimax Algorithm:

  • Game Tree: The structure of a tree that allows for all possible actions.
  • First State Initial state on the board.
  • Final State The position of the game board at which the game ends.
  • Utility Function This function assigns a numerical value to the result in the contest.

Q43. Explain Backpropagation algorithm.

Backpropagation is a Neural Network algorithm that is typically used to process unstructured data and identify patterns that are not recognized to provide better clarity. It’s a full state algorithm and has an iterative character. In the context of an ANN algorithm, the Backpropagation comes with three layers: Input layer, hidden layer, and output layer.

The input layers take in the input values and restrictions from the user or the external environment. The data moves through the Hidden layer where processing happens. After that, the processing data transforms into patterns or values that can be shared through an output layer.

Prior to processing the data, the following values must be present in the algorithm:

  • Dataset: A dataset that will be used to train models.
  • Goal Attributes Output values an algorithm is expected to be able to achieve following processing of the data.
  • Weights in a neural network, the weights are the parameters used to transform input data in the layer that is hidden.
  • Biases At every node, certain numbers, known as bias, add to the total calculated(except in input nodes).

Backpropagation is a simple ANN algorithm that uses a standard method to train models of ML. It doesn’t require a high computational power and is commonly utilized for the areas of speed-recognition, image processing along with optical character recognition(OCR).

Q44. How do you go about selecting an algorithm for solving an issue in business?

The first step is to come up with a problem statement which is in line with the issue being addressed by the company. This is crucial as it will ensure that you are fully aware of the nature of the problem as well as the input and outcome of the issue you’re looking to resolve.

The statement of the problem must be concise and not more than one sentence. As an example, let’s look at the issue of enterprise spam, which requires an algorithm to recognize it.

The issue statement is: “Is the email spam or fake?” In this scenario, the determination of whether the email is fake or spam is determined by the output.

After you have created the problem You must determine the most appropriate algorithm from the following:

  • Any classification algorithm
  • Any clustering algorithm
  • Any regression algorithm
  • Any algorithm for recommendation

The algorithm you select will depend on the particular issue you’re trying to resolve. In this instance you can proceed by using a clustering method and select a k-means algorithm to accomplish your goal of removing spam from your email system.

While you don’t need to use examples in answering questions on artificial intelligence, they will aid users to convey their message across.

Q45. Is fuzzy logic a concept? Give its applications.

Fuzzy logic is one of the subsets of AI. It’s a method of recording human learning to aid in artificial processing. It is represented in rules that follow the IF-THEN principle. The most important uses are:

  • Recognition of facial patterns
  • Washing machines, air conditioners and vacuum cleaners
  • Anti Skid brake systems and transmission systems
  • The control of the subway system as well as unmanned helicopters
  • Systems for weather forecasting
  • Project risk assessment
  • Treatment plans and medical diagnosis
  • Trading in stocks
