Disclaimer: this research code is nasty, lack of proper design or comments. Use at your own risk :-)

Prerequisites

Cython, CythonGSL

Usage

Please refer to the README in each model folder for usage.

Data format

In a corpus file, each line represents a document, which has words follow the collection_id, all separated by space.

<collection_id> <word_id> <word_id> <word_id>...

All ids begin with 0.

Vocabulary file

The vocabulary file is used by read.py, each line is a word:

<word0>
<word1>
...

So <word0> has id = 0.
