GAN Lab: An Interactive, Visual Experimentation Tool for Generative Adversarial Networks

By Minsuk Kahng, Nikhil Thorat, Polo Chau, Fernanda Viégas, and Martin Wattenberg

Overview

GAN Lab is a novel interactive visualization tool for anyone to learn and experiment with Generative Adversarial Networks (GANs), a popular class of complex deep learning models. With GAN Lab, you can interactively train GAN models for 2D data distributions and visualize their inner-workings, similar to TensorFlow Playground.

GAN Lab uses TensorFlow.js, an in-browser GPU-accelerated deep learning library. Everything, from model training to visualization, is implemented with JavaScript. Users only need a web browser like Chrome to run GAN Lab. Our implementation approach significantly broadens people's access to interactive tools for deep learning.

Working Demo

Click the following link:

https://poloclub.github.io/ganlab/

It runs on most modern web browsers. We suggest you use Google Chrome.

Development

This section describes how you can develop GAN Lab.

Install Dependencies

Run the following commands:

$ git clone https://github.com/poloclub/ganlab.git
$ cd ganlab
$ yarn prep

It's unlikely, but you may need to install some basic JavaScript-related dependencies (e.g., yarn).

Running Your Demo

Run the following command:

$ ./scripts/watch-demo

>> Waiting for initial compile...
>> 3462522 bytes written to demo/bundle.js (2.17 seconds) at 00:00:00
>> Starting up http-server, serving ./
>> Available on:
>>   http://127.0.0.1:8080
>> Hit CTRL-C to stop the server

Then visit http://localhost:8080/demo/.

The watch-demo script monitors for changes of typescript code (e.g., demo/ganlab.ts) and compiles the code for you.
