Dimensionality Reduction - What is the alternative to PCA?
Answer
A less popular alternative to PCA is PPA (Projection Pursuit Analysis). In most of the cases, PPA performs better than PCA. PPA tries to find the interesting projection by maximizing/minimizing the projection matrix. Interesting projection means when data gets split into meaningful clusters.
