Neurosis

Description

Neurosis is an example application to show off Hubris (a Haskell -> Ruby bridge) being used with non-trivial Haskell-code. See this post for an intro to Hubris and for which Neurosis was written.

Feel free to fork the code and send in pull requests if you would like to see this turn into a more sophisticated example webservice. I will be hacking on little improvements here and there as time goes on.

Up next

This was written pretty quickly for the blog post so I just used the XOR problem as validation. Next up will be running it against the popular Idris dataset to make sure everything is really working.

Installation

git clone git@github.com:larrytheliquid/neurosis.git
cd neurosis
# `sudo gem install bundler` if you don't have it
gem bundle --cached

That will take care of Ruby side of installation, unfortunately the Haskell side is a bit more tricky at the moment.

Take a look at neurosis_spec for an integration test running through rack-test, and PerceptronTest for Haskell unit tests of the underlying algorithm (if you are interested). Note that the doc directory contains a handwritten (with poor handwriting by yours truly) run of the first epoch of learning XOR, which corresponds to the values used in PerceptronTest.
