Q & A: Q: How to use the code? A: You need to put LPP.m, PCA.m in your working directory. If you want to use constrctW to construct the affinity matrix, you should also put constructW.m in your working directory. 'help LPP' for detail information. 'help constructW' for details on how to construct the affinity matrix. Q: Why LPP code does not work in my application? A: If the number of samples is much larger than the number of features, you might need to use the Kernel LPP. The affinity graph construction plays a key role, you might need to constuct the affinity matrix by your own (based on your knowledge of your application). Please refer the following papers.
