Here is a UK property price model in Haskell:

It interpolates the price of a UK house across all time from just public price paid data. It features a fairly large sparse non-linear regression problem solved with a custom implementation of the Adam optimiser (adamax variant), the `ad` autodiff package and a bit of wrangling in about 55 lines of code.
Note: it uses `deepseq` at the moment which I intend to replace with `strict-containers`: I had a version conflict issue due to `primitives`, and I don’t understand `cabal` well enough to solve it yet, but I’ll change it when I do.
Thank you those that helped me muddle through in [this thread](http://discourse.haskell.org/t/optimiser-performance-problems/8906/30).

# Jointly learning transformations and fitting a regression
A 5 parameter non-linear pipeline composed of a two Yeo-Johnson transforms, a sigmoid function which bisects the model, and a linear regression. It is jointly fitted using “threshold accepting” annealing which is also implemented herein: 53 lines of code.
