Comportex

Comportex is an implementation of Hierarchical Temporal Memory as a Clojure library. It is not a port of NuPIC, it is a separate implementation based initially on the Numenta CLA white paper but significantly evolved.

In the spirit of Clojure, Comportex is more a library than a framework. The user controls simulations, and decides what to do with them. If you want to take the set of active cells and use them to generate predictions or anomaly scores, that is up to you. It's not going to do it for you.

Comportex is not yet stable. Our aims are to:

understand the theory deeply by implementing it and experimenting with it;
help others to understand the theory via visual explanations; and
further develop the theory by attempting to apply it to new problem types.

For an applied exploration of HTM using Comportex, try the essay Predicting power consumptions with HTM by Marcus Lewis.

Documentation

For now there is the annotated source code. The main API is in the namespaces core, protocols and encoders, while the algorithms are mainly in cells, synapses and inhibition.

Parameter descriptions can be found on org.nfrac.comportex.cells/parameter-defaults.

This blog post has some explanation of the protocols.

Usage

Get Leiningen first.

Use git to clone this repository. Then, e.g. to start an interactive session:

cd comportex
lein repl

See A sample workflow with the REPL. Or check out the Notebook (browser-based REPL with super powers) in ComportexViz.
