Please solve all four questionsConsider a feedforward neural network that performs regression on a dimensional input to produce a scalar output. It has hidden layers and
each of these layers has hidden units. What is the total number of trainable parameters in the network? Ignore the bias terms.
Consider a neural network layer defined as ReLU Here is the input, is the output and is the parameter
matrix. The ReLU activation defined as ReLU:max for a scalar is applied elementwise to Find where dots, and
dots, In the following options, I condition is an indicator function that returns if the condition is true and if it is false.

Which of the following statements about the initialization of neural network weights isare true?
Two different initializations of the same network could converge to different minima.
For a given initialization, gradient descent will converge to the same minima irrespective of the learning rate.
The weights should be initialized to a constant value.
The initial values of the weights should be sampled from a probability distribution.
