 The official repo is at https://github.com/FurongHuang/SpectralLDA-TensorSpark. We refactored for the Spark coding style and interfaces when porting over for the PR. We wrote a report describing the algorithm in detail and listing test results at https://www.overleaf.com/read/wscdvwrjmtmw.
