High Performance toolbox for Extreme Learning Machines.

Extreme learning machines (ELM) are a particular kind of Artificial Neural Networks, which solve classification and regression problems. Their performance is comparable to a classical Multilayer Perceptron trained with Error Back-Propagation algorithm, but the training time is up to 6 orders of magnitude smaller. (yes, a million times!)

ELMs are suitable for processing huge datasets and dealing with Big Data, and this toolbox is created as their fastest and most scalable implementation.

Documentation is available here: http://hpelm.readthedocs.org, it uses Numpydocs.

NEW: Parallel HP-ELM tutorial! See the documentation: http://hpelm.readthedocs.org

Highlights:

Efficient matrix math implementation without bottlenecks
Efficient data storage (HDF5 file format)
Data size not limited by the available memory
GPU accelerated computations (if you have one)
Regularization and model selection (for in-memory models)

Main classes:

hpelm.ELM for in-memory computations (dataset fits into RAM)
hpelm.HPELM for out-of-memory computations (dataset on disk in HDF5 format)

Example usage::

>>> from hpelm import ELM
>>> elm = ELM(X.shape[1], T.shape[1])
>>> elm.add_neurons(20, "sigm")
>>> elm.add_neurons(10, "rbf_l2")
>>> elm.train(X, T, "LOO")
>>> Y = elm.predict(X)
