UE4 Neural Networking Plugins

This project builds on the preliminary Neurocars research.  In Neurocars we showed that we can get real time online learning for a feed forward multi-layer perceptron using a genetic algorithm and written in fairly naive C#.   This project is to create a highly optimized and scalable population of networks of the same basic structure in C++ leveraging the symmetrical processing multiple data (SIMD) instructions available in a modern processor (x64).  We will expose this high-performance AI engine to Unreal by way of a static blueprint library.  we will test it be reimplementing the same car AI test we used in Unity3D.

Project Status

An initial implementation of the C++ code using NumCpp is complete.  Initial measurements of execution time have shown it can process on input to output pass on a neural network with 10 input nodes, 3 layers of hidden nodes with 25 nodes per layer, and 10 output nodes in one-quarter of a millisecond with a variation of about one one-hundredth of a  millisecond.

The UE static blueprint library for genetic evolution of parameters is up and running in an initial form.  The Blueprint library for Feed Foward Multilayer Perceptrons is currently in development.
