Question 1

Which technique helps prevent overfitting by randomly disabling neurons during training?

Accepted Answer

Dropout

Answer

Dropout randomly zeroes neuron outputs during training, forcing the network to learn redundant representations.

Question 2

In natural language processing, what does tokenization do?

Accepted Answer

Splits text into smaller units like words or subwords

Answer

Tokenization breaks raw text into discrete units that models can process numerically.

Question 3

A convolutional neural network (CNN) is most commonly associated with which type of data?

Accepted Answer

Images

Answer

CNNs exploit spatial locality with convolutional filters, making them ideal for image data.

Question 4

What is the primary purpose of the minimax algorithm in game-playing AI?

Accepted Answer

To choose moves assuming an optimal opponent

Answer

Minimax selects moves that maximize the player's worst-case outcome against a perfectly playing adversary.

Question 5

Which scenario best illustrates algorithmic bias in AI?

Accepted Answer

A hiring model penalizing resumes from certain demographics due to skewed training data

Answer

Bias arises when skewed training data causes systematically unfair outcomes for particular groups.
