Artificial Intelligence Interview Questions

What is a heuristic function, and where is it used?

The heuristic function is used in Informed Search, and it finds the most promising path. It takes the current state of the agent as its input and produces the estimation of how close the agent is from the goal. The heuristic method, however, might not always give the best solution, but it guaranteed to find …

What is a Bayesian network, and why is it important in AI?

Bayesian networks are the graphical models that are used to show the probabilistic relationship between a set of variables. It is a directed cycle graph that contains multiple edges, and each edge represents a conditional dependency. Bayesian networks are probabilistic, because these networks are built from a probability distribution, and also use probability theory for …

What is the inference engine, and why it is used in AI?

In artificial intelligence, the inference engine is the part of an intelligent system that derives new information from the knowledge base by applying some logical rules. It mainly works in two modes: Backward Chaining: It begins with the goal and proceeds backward to deduce the facts that support the goal. Forward Chaining: It starts with …

How can AI be used in fraud detection?

The artificial intelligence can be broadly helpful in fraud detection using different machine learning algorithms, such as supervised and unsupervised learning algorithms. The rule-based algorithms of Machine learning helps to analyze the patterns for any transaction and block the fraudulent transactions. Below are the steps used in fraud detection using machine learning: Data extraction: The …

What is a market-basket analysis?

The market-basket analysis is a popular technique to find the associations between the items. It is frequently used by big retailers in order to get maximum profit. In this approach, we need to find combinations of items that are frequently bought together. For example, if a person buys bread, there are most of the chances …

Explain rational agents and rationality?

A rational agent is an agent that has clear preferences, model uncertainty, and that performs the right actions always. A rational agent is able to take the best possible action in any situation. Rationality is a status of being reasonable and sensible with a good sense of judgment.

Kindly explain different ways to evaluate the performance of the ML model.

Some popular ways to evaluate the performance of the ML model are: Confusion Matrix: It is N*N table with different sets of value that is used to determine the performance of the classification model in machine learning. F1 score: It is the harmonic mean of precision and recall, which is used as one of the …
