Code explanation
(1). Input is in folder /Data. It contains two files: Data/test.corpus, which is document-word file (each line is in the format 'docID wordID') and Data/test.dict, which is vocabulary file (each line is in the format 'word')
(2). Output is in folder /Data. It contains two file:
a) Data/test.stod.mat. It contains 3 parts:
-- 1. alpha0, which is the summation of Dirichlet priors
-- 2. alpha, which is the inferred Dirichlet prior of each topic
-- 3. twmat, which is a k (number of topics) x V (vocabulary size) matrix,
the i-th row being the i-th inferred topic distribution p(w|topic=i)
b) Data/test.topic.mat. It contains 1 part, a k x 1 cell, the i-th cell
being the topic representation of the i-th topic (which is the top 10
words ordered by p(w|topic=i))
