   Hi friends,   
      
   I am doing a project wherein I have to make an in-depth study of   
   dimensionality reduction techniques. I have come across SVD, NMF and   
   LNMF. I have understood SVD in totality but i am not able to find the   
   right resources that explain NMF in detail and bring out its clear and   
   intuitive meaning. I am ready to study the required Linear Algebra.   
      
   Can anyone point me to the right places on the net or in the book   
   library? I would be grateful.   
      
   Thanking in advance.   
   Vaibhav
