Sample Questions:
Topic 1: Feature Engineering
Question: What is the purpose of creating interaction features in feature engineering?
A) To simplify the model's architecture
B) To increase the dimensionality of the dataset
C) To capture complex relationships between existing features
D) To reduce the need for regularization techniques
Answer: C) To capture complex relationships between existing features
Explanation: Interaction features help capture non-linear interactions between existing features, enhancing the model's ability to represent complex relationships.
Topic 2: Supervised Learning
Question: In supervised learning, what is the purpose of the cost function or loss function?
A) To define the number of hidden layers in a neural network
B) To measure the complexity of the model
C) To evaluate the performance of the algorithm on the training data
D) To assign weights to different features in the dataset
Answer: C) To evaluate the performance of the algorithm on the training data
Explanation: The cost or loss function quantifies how well the model's predictions match the actual values, guiding the learning process to minimize errors.
Topic 3: Unsupervised Learning
Question: What is the key challenge when selecting the optimal number of clusters in K-Means clustering?
A) Overfitting to the noise in the data
B) Underfitting to the data distribution
C) Difficulty in handling high-dimensional data
D) Lack of a clear objective function
Answer: A) Overfitting to the noise in the data
Explanation: Selecting too many clusters can lead to overfitting, capturing noise rather than meaningful patterns in the data.
Topic 4: Reinforcement Learning
Question: In reinforcement learning, what is the role of the discount factor in the Q-learning algorithm?
A) It determines the step size of the learning rate
B) It adjusts the exploration rate of the agent
C) It discounts future rewards to account for their present value
D) It controls the number of episodes in training
Answer: C) It discounts future rewards to account for their present value
Explanation: The discount factor adjusts the weight of future rewards, allowing the agent to prioritize immediate rewards over delayed rewards.
Topic 5: Model Metrics, Tuning
Question: Which metric is particularly useful in situations where false positives are more concerning than false negatives?
A) Accuracy B) Precision C) Recall D) F1 Score
Answer: B) Precision
Explanation: Precision focuses on the proportion of true positives among all predicted positives, making it suitable when minimizing false positives is crucial.
Topic 6: Deep Learning
Question: What is the purpose of a vanishing gradient problem in deep neural networks?
A) To accelerate convergence during training
B) To prevent overfitting in the model
C) To introduce regularization in the optimization process
D) To impede the learning of lower layers due to weak gradients
Answer: D) To impede the learning of lower layers due to weak gradients
Explanation: The vanishing gradient problem can hinder the learning of lower layers in deep networks, leading to slow or ineffective training.
