hyperopt-nnet

This package provides a hyperopt-compatible neural network implementation.

Currently, it can be used to tune neural network hyperparameters for data sets provided as skdata protocols.

See the ./examples subdirectory for sample training scripts (e.g. nips2011_nnet.py) and a plotting script (plot_trials.py).

The hpnnet.nips2011 file implements the search parameterization used in Bergstra, Bardenet, Bengio, and Kegl ("Algorithms for Hyper-parameter Optimization") from NIPS 2011.
