Pivot… Hello World Synapse, with MNIST

I started working on Synapse (AI platform) with the goal of creating an AI that would drive the vehicles in my racing game Super Truckin’. Unfortunately, after attempting to get Super Truckin’ up and running I have determined I will have to “pivot”.

When I updated Super Truckin’ to the new Unity 3d build, I was forced to update the Edy’s Vehicle Physics engine and broke everything. There was no “automatic update” of the changes and there was significant architectural changes in the physics.

Another challenge faced was that the libraries I was going to use for the feed forward and back propagation methods were in Encog (C#) and that library is completely incompatible with Unity, as Unity only supports .NET 2.0 and Encog is .NET 3.6.[Encog]

This doesn’t change my goal as I was still planning on making my own feed forward , and back propagation methods, but it does put it off for a while until I can build the neural network pieces of my platform.

With these bumps in the road, and my patience to see some results short, I have now chosen to make my first complete project with Synapse one that is based on the MNIST data set. A “hello world” set of data for AI developers. For those not familiar, MNIST is a set of hand drawn numbers (28×28 pixels). [MNIST Data]

This does change my platforms first implementation from an unsupervised network, to a supervised network since MNIST is labeled, meaning the system isn’t going to “learn” intuitively what the number is, it will have to be told after each attempt whether the number the system believes it is, is the correct number. This is a drastic change, but one that does test whether my original definition of an AI is still valid, or if it was only valid for unsupervised AI’s.[Original AI Definition]

Is it going to be easy to switch a system from unsupervised to supervised learning? We will find out…
