Call to Arms: HTM.java needs you!

Goals

The primary goal of this library development is to provide a Java version of NuPIC that has a 1-to-1 correspondence to all systems, functionality and tests provided by Numenta's open source implementation; while observing the tenets, standards and conventions of Java language best practices and development.

By working closely with Numenta and receiving their enthusiastic support and guidance, it is intended that this library be maintained as a viable Java language alternative to Numenta's C++ and Python offerings. However it must be understood that "official" support is (for the time being) currently limited to community resources such as the maintainers of this library and Numenta Forums / Message Lists and IRC:

• NuPIC Community

Installation

NOTE: For simple intructions see: INSTALL.txt

Eclipse Environment Setup Wiki

An Eclipse IDE .project and .classpath file are provided so that the cloned project can be easily set up inside of Eclipse. For the time being, the Eclipse IDE is the only "pre-made" project configuration.

In addition, there are "launch configurations" for all of the tests and any runnable entities off of the "htm.java" main directory. These may be run directly in Eclipse by right-clicking them and choosing "run".

After download by clone or fork:

Execute a quick sanity check by running all the tests from within the <path to git repo>/htm.java

gradle check  # Executes the tests and runs the benchmarks

--or--

gradle -Pskipbench check  # Executes the tests w/o running the benchmarks

Note: Info on installing gradle can be found on the wiki (look at #3.) here

Linux Gradle Issues? see the wiki here.
