Computer Vision Lab (up to 10 points)

Basic implementations

Check basic implementations on CIFAR10 in the Deep Learning Lab project here

Goals:

• Implement some basic convolutional networks
• Implement different data augmentation
• Implement VGG model

Advanced topologies

• Wide Resnet (1 point)

• Dense Nets (1 point)

Gender Recognition (3 point)

Images from "Labeled Faces in the Wild" dataset (LFW) in realistic scenarios, poses and gestures. Faces are automatically detected and cropped to 100x100 pixels RGB.

Training set: 10585 images

Test set: 2648 images

Python Notebook: here

Python code: here

Goals:

• Implement a model with >98% accuracy over test set

• Implement a model with >95% accuracy with less than 100K parameters

Car Model identification with bi-linear models (5 points)

Images of 20 different models of cars.

Training set: 791 images

Test set: 784 images

• Version 1. Two different CNNs:

  Python code: here

• Version 2. The same CNN (potentially a pre-trained model)

  Python code: here

Goals:

• Understand the above Keras implementations:
  • Name the layers
  • Built several models
  • Understand tensors sizes
  • Connect models with operations (outproduct)
  • Create an image generator that returns a list of tensors
  • Create a data flow with multiple inputs for the model

Suggestion:

• Load a pre-trained VGG16, Resnet... model
• Connect this pre-trained model and form a bi-linear
• Train freezing weights first, unfreeze after some epochs, very low learning rate
• Accuracy >65% is expected
