Neural Network Playground

This is a tool to experiment basic neural network architectures and build intuitions on machine learning.

The main idea is provide an environnement to experiment how data and learning parameters affects the network training.

Play

The online demo is available here :

How does it work

To get a first sight, click on the play button and watch the prediction evolving towards the labeled data.

The lab has two main sections :

• Generate labeled data.

• Train the network and watch the metrics.

Labeled Data

Training data has the following shape : {a, b} => label, for a pair of numbers a and b, we will associate an expected number label.

a and b are represented on a 2d plane on the x and y axes respectively and the label is viewed by a color scale.

Training the network

The goal of the network is to understand the relationship between {a, b} and the expected label.

The achieve this task you may need to tweak several things, the most important are :

• The neural network shape and activation functions.
• The batch size.
• The optimizer settings.
