Cooperative Learning of Energy-Based Model and Latent Variable Model via MCMC Teaching

Cooperative Learning of Energy-Based Model and Latent Variable Model via MCMC Teaching

This repository contains a tensorflow implementation for the paper "Cooperative Learning of Energy-Based Model and Latent Variable Model via MCMC Teaching". (http://www.stat.ucla.edu/~ywu/CoopNets/main.html)

Requirements

• Python 2.7 or Python 3.3+
• Tensorflow r1.0+
• Scipy
• pillow

Usage

First, download Imagenet-scene dataset and save it to ./data directory:

$ python download.py scene

To train a model with alp dataset:

$ python main.py --category alp --data_dir ./data/scene --output_dir ./output --num_epochs 300 --batch_size 100 --d_lr 0.01 --g_lr 0.0001

synthesized results will be saved in ./output/alp/synthesis

To test generator by synthesizing interpolation results with trained model:

$ python main.py --test --sample_size 144 --category alp --output_dir ./output --ckpt ./output/alp/checkpoints/model.ckpt

testing results will be saved in ./output/alp/test

Results

Results of MIT Place205 dataset

Descriptor result

Generator result
