    Q4- Mention the difference between statistical AI and Classical AI ?

    Statistical AI is mainly focused with “deductive approach” cognition, such as given a series of patterns, predicting the trend, and so on. While classical AI is primarily concerned with “deductive” cognition given a set of restrictions, extract a conclusion, and so on.

    Q5- What does a hybrid Bayesian network contain?

    A hybrid Bayesian network has characteristics that are both discrete and continuously.

    Q6- What is agent in artificial intelligence?

    Agent is defined as anything that senses its surroundings through sensors and responds on it through effectors. Agents include robots, programmes, and humans, among other things.

    Q7- What does Partial order or planning involve?

    Instead of looking over conceivable situations, simple layout planning entails exploring over the space of feasible plans. The goal is to build a plan step by step.

    Q8- What is Neural Network in Artificial Intelligence?

    In artificial intelligence, a neural network is a simulation of a biological brain system that receives, processes, and outputs input based on an algorithm and scientific data.

    Q9- What is the future of Artificial Intelligence?

    Artificial intelligence has had an impact on many people and practically every industry, and it is anticipated to continue. AI has been the primary driver of developing technologies such as the Internet of Things, big data, and robots. AI can utilize the power of vast amounts of data and choose the best option in a split second, which is nearly difficult for a regular human to do. AI is advancing crucial human-centered fields such as cancer research, cutting-edge climate change technology, smart transportation, and space exploration. It has seized the central place of computer advancement and development, and it is unlikely to relinquish it in the near future. Artificial intelligence will have a greater influence on the globe than anything else in human history.

    Q10- How are Artificial Intelligence and Machine Learning related?

    Artificial Intelligence and Machine Learning are two well-known yet sometimes misinterpreted terms. Artificial intelligence (AI) is a branch of computer science that allows machines to simulate human understanding and behaviors. Machine Learning, on the other hand, is a subclass of Artificial Intelligence which involves supplying computers enough data so that they may understand for themselves from all of the connections and models. Machine Learning models are widely deployed to create Artificial Intelligence.

    AI may be tackled in several ways, for example by developing a computer simulation that executes a set of sector specialist rules. Machine Learning is a component of Artificial Intelligence (AI) (ML). The study of inventing and deploying algorithms that can benefit from prior experiences is known as machine learning (ML). If a particular strategy has already been seen, users can predict whether it is going to appear again.

    Q11- What are different types of Machine Learning?

    • Supervised Learning:

      The simplest sort of machine learning called supervised learning. It is used to provide labelled data into the machine to train it. A labelled dataset is a collection of examples which have been labelled with one or more categories (information tags). The labelled data is provided to the machine one at a time until the system detects it on its own. It’s the same as a teacher trying to teach a child all of the labelled cards in a deck of cards one by one. In supervised learning, the data itself serves as the instructor.

    • Unsupervised Learning:

      Surprisingly, unsupervised learning is the total opposite of supervised learning. It is used to represent data that does not include labels or information tags. The algorithm is given a large amount of data as well as tools for understanding data attributes. The machine will arrange the data into clusters, categories, or groupings which make some sense. The learning model is excellent because it can take a large quantity of random data as input and make logical sense of it.

    • Reinforcement learning:

      The reinforcement learning method is one of the learning models discussed above. It is a model that learned from its experiences. When we introduce a reinforcement learning model into any environment, it produces numerous errors. To encourage positive learning and to improve the model efficient, we offer a positive feedback path whenever the model works well and a negative feedback message whenever it makes mistakes.

    Q12- What are Bayesian networks?

    A Bayesian network is a probabilistic graphical model that is depicted as an undirected graph but also is based on a collection of variables with their relationships. Bayesian networks are built on probability distributions and use probability theory to anticipate events and discover abnormalities. Bayesian networks are used to accomplish tasks such as prediction, anomaly detection, reasoning, insight generation, diagnostics, and decision-making. For example, a Bayesian network might be used to show the likelihood relationships between illnesses and symptoms. Using the symptoms, the networks could be used to determine the likelihood of particular illnesses being present.

    Q13- What is Reinforcement learning?

    Reinforcement learning is a branch of machine learning that uses reward-based models to anticipate and make decisions. It uses a responses approach to encourage a machine for making smart decisions. Whenever the machine does not operate well, it receives negative input. This encourages the computer to discover the optimum behaviour in a particular scenario.

    Q14- What is Natural Language Processing?

    Natural Language Processing (NLP) is a category of artificial intelligence involved with teaching computers to comprehend and engage in human languages in the same manner that people do.

    NLP integrates human speech rule-based modelling with statistics, machine learning, and deep learning techniques. This allows a machine to completely grasp and interpret human language, whether spoken or written. NLP is used in voice-activated GPS systems, speech-to-text systems, customer care chat boxes, and other applications.

    Natural language processing includes a wide range of methods for evaluating human language, such as statistical and machine learning techniques, as well as rule-based and algorithmic approaches.

    Q15- What is Fuzzy logic?

    Fuzzy logic (FL) is an Artificial Intelligence thinking style that is similar to human thinking. This reasoning states that the outcome can have any value between TRUE and FALSE (digitally, 0, or 1).

    For example, the answer may be definitely yes, probably yes, not sure, probably no, or definitely no.

    According to conventional logic, a computer may accept input and create a definite output that is True or False, which is comparable to a human YES or NO.

    Q16- What is a Chatbot?

    A chatbot is a computer software that mimics and analyses human conversations. They may engage with us in the same way that any other genuine person would. Chatbots can range from simple software that answer questions in a single line through complex assistants which can learn and improve to achieve an increased rate of personalization while they acquire and analyze the data.

    Q17- What is Hidden Markov Model (HMMs) is used?

    Markov Chain Models are a common tool for modeling time – series or sequential behaviour. These are found in nearly all modern speech recognition systems.

    Q18- What is Deep Learning?

    Deep learning simulates how human brain works, in that it improves from experiences. It solves complicated issues by adopting neural network techniques.

    19- What is Tower of Hanoi?

    Tower of Hanoi is a mathematical problem which demonstrates how recursion may be used as a tool in developing an algorithm to solve a specific issue. We will solve the Tower of Hanoi using AI and a decision tree and a breadth-first search (BFS) technique.

    20-Explain Alpha–Beta pruning.

    Alpha-Beta pruning is a search technique which attempts to limit the number of nodes in the search tree which are investigated by the minimax algorithm. It may be used to trim whole subtrees and leaves at ‘n’ depths.
