BitBrain C Code

GitHub version of code repository for BitBrain and Sparse Binary Coincidence (SBC) memories: Fast, robust learning and inference for neuromorphic architectures by Michael Hopkins, Jakub Fil, Edward George Jones and Steve Furber.

Demonstrates a new technique for learning and inferring using a spiking approach, especially suitable for constrained hardware.

Building

If you have OpenMP and clang-8 installed, you can run this to build the main bb executable:

clang-8 full_mnist_2048.c -O3 -march=native -fopenmp -lm -lomp -o bb

It should still be buildable with other compilers if you don't have OpenMP or clang, with something like:

gcc full_mnist_2048.c -O3 -lm -o bb

Building without OpenMP will result in a slower executable, but it should be functionally the same.

Running

In this folder, run the executable like this from a shell:

./bb

On my laptop this takes about thirty seconds on a non-OpenMP build. The expected output is:

346 wrong = 96.540 pct correct
