Super sparse multi-class machine learning with Cython.
thinc is a Cython library for learning models with millions of parameters and dozens of classes. It drives http://honnibal.github.io/spaCy , a pipeline of very efficient NLP components. I’ve only used thinc from Cython; no real Python API is currently available.
Currently the only model implemented is the averaged perceptron, which is surprisingly competitive for these problems.
