thinc 3.3

Learn sparse linear models

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.

Despite the recent enthusiasm for deep learning, linear models can still perform very well, if the right feature engineering is applied. The key is adding good conjunction features — e.g., “next_word=X && next_next_word=Y”. For this, I have a helper-class thinc.features.Extractor, which you pass a list of templates, which then performs your feature extraction, given an array of atomic context items.
