Watch a neural network think. Written in Python.

Neural Network Animation

Watch a neural network think. Written in Python.

Requires the FFMPEG codec. To install use the command "brew install ffmpeg".

In the video, the synapses are represented by lines. A thickening of a line represents the synaptic connection between two neurons growing stronger. As the thickeness of the lines change, you can see the neural network learning. Flashes of light represent neural activity.

To run the program use the command "python main.py". It will generate a mp4 file in the same folder.

You can read more about it and watch the video here: https://medium.com/@miloharper/how-to-generate-a-video-of-a-neural-network-learning-in-python-62f5c520e85c

simple-neural-network

A neural network written in Python, consisting of a single neuron that uses back propagation to learn.

multi-layer-neural-network

A multi layer neural network written in Python, which can be trained to solve the XOR problem.

visualise-neural-network

Generates a static diagram of a neural network, where each neuron is connected to every neuron in the previous layer.

self-writing-code

Code which randomly mutates in a virtual environment of 100x100 squares with a random distribution of food. If the code doesn't eat, it dies. The code which lives the longest is saved.

neural-network-with-bias

Demonstration of bias in a neural network.

neural-network-show-absolute-error

A demonstration of how you can graph the error of the neural network decreasing over time.

deep-q-learning

A demonstration of how Deep Q Learning can solve the NChain-v0 game.
