# Variational Integrator Networks

## Overview

### Link to paper

![Variational Integrator Networks for Physically Structured Embeddings](https://arxiv.org/abs/1910.09349)

### Run experiment

`python run_exp.py root_dir model_name system_name observations num_train_traj num_train_steps seed`

e.g. 

`python run_exp.py experiments VIN_VV pendulum pixels 1 60 1`

### Dependencies

- tensorflow 2.1

- tensorflow_probability

- gin-config

- see `requirements.txt`

## Example: Ideal Pendulum, Noisy Observations

__Setup__

- Train on 15s of observations (150 datapoints)

- Test on noisless initial state, forecast for 10s



  

  



#### Recurrent Residual Network (Left) / Variational Integrator Network (Right) 

## Example: Ideal Pendulum, Pixel Observations

__Setup__

- Train on 6s of 28x28 pixel observations (60 datapoints)

- Infer latent initial state from 1s of data

- Forecast for 10s, reconstruct latent path
