Question 1

Why is the SVM optimization problem often referred to as a convex optimization problem?

A : The objective function has a single global minimum ensuring unique solutions.

B : The kernel functions used are linear, simplifying the optimization process.

C : The support vectors form a convex set leading to easier optimization.

D : The decision boundary is always linear, making optimization straightforward.

Answer: A

Question 2

Which approach is most effective for feature selection in large-scale data?

A : LASSO

B : Random Forest

C : Recursive Feature Elimination

D : PCA

Answer: A

Question 3

Which optimization algorithm is known for its use of momentum to accelerate convergence and improve gradient descent performance in deep learning?

A : RMSprop Optimizer adapts learning rates based on recent gradients but does not incorporate momentum.

B : Stochastic Gradient Descent (SGD) with Momentum is used to enhance convergence speed by adding a fraction of the previous update to the current gradient.

C : Adagrad Optimizer adjusts learning rates based on historical gradients but does not use momentum.

D : Adam Optimizer uses adaptive learning rates for different parameters and combines momentum with adaptive gradients for improved training.

Answer: D

Question 4

What should you focus on when interpreting A/B test results?
