Question 1

Which of the following best describes machine learning?

A system that follows explicitly programmed rules to make decisions A subset of AI where systems learn patterns from data without being explicitly programmed A programming language used exclusively for robotics A type of database management system

Correct Answer:

A subset of AI where systems learn patterns from data without being explicitly programmed

Question 2

In a supervised learning model, what is the role of labeled training data?

It is used only to test the model after training is complete It provides input-output pairs so the model can learn the mapping between them It stores the model's weights after training It eliminates the need for a validation set

Correct Answer:

It provides input-output pairs so the model can learn the mapping between them

Question 3

What is the primary purpose of a neural network's activation function?

To initialize the weights of the network To introduce non-linearity so the network can learn complex patterns To split data into training and testing sets To calculate the learning rate

Correct Answer:

To introduce non-linearity so the network can learn complex patterns

Question 4

Which machine learning approach is best suited for training an agent to play a video game by rewarding good moves?

Supervised learning Unsupervised learning Reinforcement learning Transfer learning

Correct Answer:

Reinforcement learning

Question 5

What does 'overfitting' mean in the context of machine learning?

The model performs poorly on both training and test data The model learns the training data too well, including noise, and fails to generalize The model is too simple to capture patterns in the data The training process takes too long to converge

Correct Answer:

The model learns the training data too well, including noise, and fails to generalize
