sdr

Functions for working with Sparse Distributed Representation

one of biggest problems in AI --no, the only problem in AI-- is the problem of representation So said a retiring AI researcher

If you don't know what SDRs are, you should go learn about them. numenta.org Or watch these videos for an easy to follow introduction.

Usage

Your SDR arrays are always assumed to be in order from least to greatest. The functions use this assumption to optimize performance.

var sdr = require('sdr');

sdr.union(
  [0, 10, 15, 30],
  [0,  5, 10, 20]
);
//-> [0, 5, 10, 15, 20, 30]

sdr.intersect(
  [1, 2],
  [2, 3]
);
//-> [2]

sdr.sparsity([0, 10, 20], 100);
//-> 0.03

sdr.capacity(2048, 40);
//-> 2.3717785116453587e+84
