LSTM-Autoencoder and LSTM-Predictor in Tensorflow

LSTM Autoencoder and LSTM Future Predictor in Tensorflow.

This is a simple implementation based on this paper : https://arxiv.org/abs/1502.04681

Requirement

1. Tensorflow 1.4.0
2. Python 3.5.4
3. Python packages : numpy, matplotlib, os, argparse, scipy

Usage

Implement reconstruction or future prediction after data generation

• Data generation using rotation and shift : Image_generation.ipynb
  • Reconstruct data using LSTM autoencoder : Autoencoder.ipynb
  • Input Reconstruction and Future Prediction : AE_with_Predictor

Results

From Composite Model

Data sequence(left to right) : 0,1,...,t-1,t
