This branch implements zero-mean factor analyzer as a new obsmodel. It contains a ZeroMeanFactorAnalyzerObsModel.py and a toy dataset for mixture of zero-mean factor analyzers D3C2K2_ZM.py.
Example
python -m bnpy.run D3C2K2_ZM FiniteMixtureModel ZeroMeanFactorAnalyzer VB --K 2 --nLap 200 --printEvery 50
FA Toy Data. 2 true clusters.
size: 2500 units (single observations)
dimension: 3
Allocation Model: Finite mixture with K=2. Dir prior param 1.00
Obs. Data Model: Zero-mean factor analyzer.
Obs. Data Prior: Gamma shape and invScale param on precision of factor loading matrices: f, g
f = 0.001 ...
g = 0.001 ...
