Contents

1. Gradient Descent : Not Pytorch -- simple gradient descent with several different conditions.
2. Logistic Regression : Not Pytorch
3. Deep Neural Networks : predicting handwritten numbers with MNIST dataset
4. Convolutional Neural Networks : predicting handwritten numbers with MNIST dataset
5. Recurrent Neural Networks : predicting future stock price trend with RNN(LSTM cells)
6. AutoEncoders    
   6.1 Feed Forward AutoEncoder : regenerating MNIST images with a feed forward AutoEncoder    
   6.2 Convolutional AutoEncoder : regenerating MNIST images with a convolutional AutoEncoder    
   6.3 Beta-Variational AutoEncoder : regenerating MNIST images with a Beta-Variational AutoEncoder
       I found it hard to build a vanilla VAE. So I adopted the Beta-VAE with an incremental Beta to help convergence.    
   6.4 Sparse AutoEncoder : regenerating MNIST images with a sparse AutoEncoder with 1300 hidden code units.    
   6.5 Denoising AutoEncoder : regenerating MNIST images that has gaussian noise with a denoising AutoEncoder.
7. Deep Q Network    
   7.1 Feed Forward DQN : training Cartpole with an RL feed forward DQN    
   7.2 Convolutional DQN : training Cartpole with an RL Convolutional DQN. Referenced here, but failed to master the game

NOTE : All Neural Network Models are built without train/dev/test splits. Models will be prone to overfitting.
