21. Explain the Hidden Markov Model.

The Hidden Markov model is a probabilistic model which is used to identify the probabilistic character of any event. It says that an observed event is related to a set of probability distributions. If a system is being modeled into a Markov’s chain, then the main goal of HMM is to identify the hidden layers of the Markov’s chain. Hidden means that the particular state is not observable to the observer. It is generally used for temporal data. HMM finds its application in reinforcement learning, temporal pattern recognition, etc.

22. What do you understand by hyperparameters?

Hyperparameters are the parameters that control the entire training process. These variables are adjustable and have a direct impact on how successfully a model trains. They are declared beforehand. Model hyperparameters, which cannot be inferred while fitting the machine to the training set because they refer to the model selection task, and algorithm hyperparameters, which have no effect on the model’s performance but affect the speed and quality of the learning process, are two types of hyperparameters.

The selection of good hyperparameters is crucial for the training process. Activation function, alpha learning rate, hidden layers, number of epochs, number of branches in a decision tree, etc. are some of the examples of hyperparameters.

23. What is Overfitting?

Overfitting is a concept in data science when a data point does not fit against its training model. When the raining model is fed with data, there is a possibility that it might encounter some noise that cannot fit into the statistical model. This happens when the algorithm cannot perform accurately against unseen data.

24. What are the techniques used to avoid overfitting?

If we can detect overfitting at an early stage, it will be very useful for our training model. There are several methods up our sleeves that can be used to avoid overfitting-

Cross-validation: Cross-validation is a resampling technique for evaluating machine learning models on a small sample of data.
Remove features: We can remove the unnecessary features of the models to encompass the outliers.
Early stopping: Early stopping is a type of regularization used in machine learning to minimize overfitting when using an iterative method like gradient descent to train a learner. Early stopping criteria specify how many iterations can be completed before the learner becomes over-fit.
Training with more data: We can train our model with more data to accommodate outliers.
Regularization: In machine learning, regularization is a method to solve the over-fitting problem by adding a penalty term with the cost function.
Ensembling: Ensemble learning refers to combining the predictions from two or more models.

25. What is Natural Language Processing?

Natural Language Processing (NLP) is a field of Artificial Intelligence, concerned with giving computers the ability to understand and interact in human languages in a way humans can.

NLP combines rule-based modeling of human language with statistical, machine learning, and deep learning models. This makes a computer fully understand and comprehend human language in the form of voice or text. Voice-operated GPS systems, speech-to-text systems, customer service chat boxes, etc. use NLP.

26. What is the difference between eigenvalues and eigenvectors?

Eigenvalues are the coefficients given to eigenvectors that determine the length or magnitude of the vectors. Eigenvalues are unit vectors having magnitude 1. A negative eigenvalue, for example, may scale the eigenvector in the opposite way.
Eigenvectors are unit vectors, meaning their length or magnitude is the same as 1.0. They’re also known as right vectors, which simply means “column vectors” (as opposed to a row vector or a left vector). A right-vector is a vector in the traditional sense.

27. What are the different components of an expert system?

An expert system is a computer program that simulates the judgement and behavior of a human or an organization with expert knowledge and expertise in a particular field using artificial intelligence (AI) technologies.

The expert systems belong to an important domain of Artificial Intelligence, which is used to solve complex problems using extraordinary human intelligence and expertise.

The different components used to build an expert system are:

Knowledge base- It is a storage area that contains domain-specific, high-quality knowledge.
Inference engine- The Inference engine uses and manipulates the knowledge from the knowledge base.
User Interface- It provides interaction between the expert system and the user.

28. What are some differences between classification and regression?

Regression and classification are both supervised learning algorithms. Both work on labeled data and are used to predict in machine learning. The difference, however, arises from the manner in which they are used.

29. What is an Artificial Neural Network? What are some commonly used Artificial Neural networks?

Artificial Neural networks, simply called Neural networks, are computer systems based on units called nodes or artificial neurons, which resemble the neurons in human brains. Each node can transmit a signal from one node to another.

30. What Is Game Theory?

Game theory is a branch of AI that attempts to define a strategic game with predefined rules and outcomes between two players of equal rationality. Every player is selfish and tries to maximize the reward to be obtained using a particular strategy. All the players abide by certain rules in order to receive a playoff- which is a reward. Therefore, a game can be defined as a set of players, actions, strategies, and a final reward.

Game theory and AI are related to each other and complement each other. Game theory is used in AI situations where multiple agents are in an environment trying to achieve a goal. Various games are logical and have a set of pre-decided rules like chess, poker, etc., which can be made available digitally with the help of Artificial Intelligence and Game Theory.
