Deep Learning End Term 13 Sept 2026 — Question 7

Select all that apply.

1. A

2. B

   Adding more hidden layers with identity activations increases the representational capacity beyond that of a single-layer linear model.

3. C

   Replacing the identity activation with a nonlinear function such as sigmoid enables the network to learn nonlinear decision boundaries.

4. D

   With identity activations, the network can still learn arbitrary decision boundaries provided enough hidden neurons are used.
