Which search algorithm is guaranteed to find the optimal solution when using an admissible heuristic?
Answer: A* search
A* search is optimal when its heuristic never overestimates the true cost to the goal.
In machine learning, what problem occurs when a model performs well on training data but poorly on unseen data?
Answer: Overfitting
Overfitting means the model memorized training-specific noise instead of learning generalizable patterns.
Which component of an expert system contains the domain-specific facts and rules?
Answer: Knowledge base
The knowledge base stores the facts and if-then rules that the inference engine reasons over.
What does the activation function in a neural network primarily provide?
Answer: Non-linearity
Activation functions like ReLU introduce non-linearity, letting networks model complex relationships.
In reinforcement learning, what does the agent receive from the environment after taking an action?
Answer: A reward signal and new state
The environment returns a reward and the next state, which the agent uses to improve its policy.
Which of the following is an example of unsupervised learning?
Answer: Customer clustering by purchase behavior
Clustering groups unlabeled data by similarity, requiring no predefined output labels.
The Turing Test is designed to evaluate what aspect of a machine?
Answer: Its ability to exhibit human-indistinguishable conversation
Alan Turing proposed the test to judge whether a machine's conversational responses are indistinguishable from a human's.
