Practice Questions

1. Your CNN model achieves 95% training accuracy but only 78% validation accuracy. What techniques would you use to address this gap?
2. You need to deploy a Deep Learning model to a mobile device. What optimization techniques (quantization, pruning, distillation) would you apply and in what order?
3. A GAN is experiencing mode collapse where the generator only produces one type of image. What causes this and how do you fix it?
