Q1.What is the primary function of the activation function in a deep neural network?

mcq
To introduce non-linearity so the network can approximate non-linear functions
To normalize the input vectors to standard normal distribution
To speed up GPU matrix multiplications during the forward pass
To prevent integer overflow in float64 arrays

Q2.Which of the following activation functions suffers from the vanishing gradient problem when inputs are very large positive or negative numbers?

mcq
Sigmoid
ReLU (Rectified Linear Unit)
Leaky ReLU
ELU

Q3.Which techniques help prevent vanishing gradients in deep architectures?

msq
Residual skip connections (ResNet)
Batch Normalization / Layer Normalization
Using ReLU or GELU activations
Increasing the learning rate to 10.0
