Instructions for Teachers
This Practical covers fundamental CNN development, training and testing. Three exercises of increasing difficulty will be administered, each of them covering a different aspect of CNNs. All the proposed solutions will be implemented in Python, using the PyTorch package. The proposed exercises consist in:
- Exercise 1: the simple MNIST dataset will be used to train and test three simple CNNs composed respectively of one, two, and three convolutional layers. Pooling and batch normalisation will be also added to compare the different performances.
- Exercise 2: a deep network (e.g., LeNet-5) pretrained on ImageNet will be loaded. Next, the performances on MNIST and CIFAR10 will be evaluated after a fine-tuning stage. Different experiments will be made, considering different conditions, such as fine-tuning all the layers or only the last ones.
- Exercise 3: the filters of a learned network will be visualized.
- Exercise 4: several datasets (such as CIFAR10 and SVHN) will be tested using other different architectures (such as ResNet and VGG16) and the final performances on the test sets will be evaluated.
