In this project, we implement NMF algorithms with sparseness constraint, label constraint as well as the basic NMF. A face recognition system is built using features extracted from different NMF algorithms on the AR face database
The module Cprojection need to be compiled using Cython cd src/ python setup.py build_ext --inplace
This compile process take the code Cprojection.pyx and genenrate Cprojection.c, Cprojection.so in the current directory
PCA and NMF are tested on 3 datasets: cbcl, orl, ar, which are implemented in egs/cbcl, egs/orl, egs/ar respectively
-
cbcl cd egs/cbcl bash run.sh
-
orl cd egs/orl bash run.sh
-
ar cd egs/ar bash run.sh [num_man] [num_woman] [num_basis]
note: need to specify directory of data at the beginning of each run.sh experiment scripts
