Usage

###Input file format: <br/> DocNumLabels label1 label2 ... @ DocNumWords word1 word2 ...<br/> DocNumLabels label1 label2 ... @ DocNumWords word1 word2 ...<br/> DocNumLabels label1 label2 ... @ DocNumWords word1 word2 ...<br/>

Each row represent one document with labels. DocNumLables means the number labels of document. DocNumWords means the number words of document. Each label is integer and represent one label. Each word is integer and represent one word.<br/> <br/> demo/twtm.demo.input is a simple demo input file.<br/> demo/label.txt is the label dictionary file. The word in row 1 means the label0.<br/> demo/words.dic is the word dictionary file.<br/> <br/> <br/> ###Training:<br/>

./twtm est <input data file> <setting.txt> <num_topics> <model save dir>

Example: <br/>

./src/twtm est demo/twtm.demo.input src/setting.txt 10 demo/model

Some model training parameters are set in the file "setting.txt".

###Inference:<br/> There are two methods to inference a new document's topic distribution. <br/> One is still using the labels of new document to inference.<br/>

./twtm inf <input data file> <setting.txt> <model dir> <prefix> <output dir>

Example: <br/>

./src/twtm inf demo/twtm.demo.input src/setting.txt demo/model/ final demo/output/

We can get the doc-topics-dis.txt file in output dir. The file indicates the topic distribution in input data file. The values in the file should be exp(.) so that we can konw that exact probablility.

The other one is just using the words of new document. So with the TWTM model, we can inference some new document without any label just like LDA model. <br/>

./twtm lda-inf <input data file> <setting.txt> <model dir> <prefix> <output dir>

Example: <br/>

./src/twtm lda-inf demo/twtm.demo.input src/setting.txt demo/model/ final demo/output/
