Welcome to the session dedicated to all UGC NET aspirants at Professor Academy! In today’s discussion, we will explore the Top 10 AI Questions that are crucial for your examination preparation. These questions have been repeated in previous years of the UGC NET examination, thus familiarizing yourself with these will cover approximately 80% of the Artificial Intelligence syllabus. Let’s dive in!
The A algorithm is optimal when:*
Answer: Option 1 is correct. The A* algorithm is a popular pathfinding algorithm that efficiently searches for the shortest path between two points on a graph. Its optimality is guaranteed when the heuristic function is admissible, meaning it does not overestimate the cost to reach the goal node.
Which artificial intelligence technique enables computers to understand the associations and relationships between objects and events?
Answer: Option 4, Pattern Matching, is correct. This technique identifies similarities or patterns within data and is used in various AI applications to recognize relationships between objects or events.
Where does the value of Alpha Beta search get updated?
Answer: Option 1 is the correct answer. The values of Alpha and Beta in Alpha Beta pruning get updated along the path of the search, optimizing the Minimax algorithm by reducing the number of nodes evaluated.
Calculate the total output for the input values given weights: 1, 2, 3, 4 and inputs: 5, 7, 10, 30 with a constant of proportionality equal to 3.
Answer: The output is 57. You multiply the weights by the inputs and then apply the transfer function.
Which AI system mimics the evolutionary process?
Answer: Option C; Genetic Algorithm is correct. This AI system uses mechanisms such as selection, crossover, and mutation to find increasingly better solutions through a natural selection process.
Identify the learning algorithms that represent classification.
Answer: Correct options are A and B only: Logistic regression and Back propagation are classification algorithms.
Match the following:
Answer: 1 - NLG; 2 - NLG; 3 - NLG; 4 - NLU
What are the characteristics of artificial neural networks?
Answer: All statements are correct.
Overfitting is expected when:
Answer: Option 2 is correct. Overfitting occurs when the training error decreases with training iterations, but the test set error increases.
Which agent deals with happy and unhappy states?
Answer: Option 4, Utility-based agent, is correct. This agent maximizes satisfaction or utility in its decisions.
What is the A algorithm used for?*
What does pattern matching in AI do?
How does Alpha Beta pruning work?
What is overfitting in machine learning?
What is a utility-based agent?
