Non-Negative Matrix Factorization (NMF) | Multiplicative Update Rules By Lee And Seung

Показать описание

NMF Algorithm
Non-negative Matrix Factorisation (NMF): Family of linear algebra algorithms for identifying the latent structure in data represented as a non-negative matrix.

Input: matrix X , rank k.
Output: Two k-dimensional factors W and H approximating X

I used Multiplicative Update Method introduced by Lee and Seung in 1999 in order to factorize the input matrix.

@Ahmad Varasteh I think there might be an error @2:19 for the "W" equation on the bottom right: the numerator should be "XH^T" rather than "W^T X"
Your github code has the correct version

2:20 I know this learning rates lead to multiplicative update rules and guarantee non-negativity, but would it be possible that the learning rates are too large at some iteration to guarantee the convergence of NMF?

Can you please explain what does basis vectors actually represent In NMF

Thanks a lot ; Please do you have an idea ; how to optimize a boolean matrix factorization (Binary matrices)?

Very cool video.. Just a doubt on how do we choose K ?

abhishekpatil

what does "not always positive semi-definite" mean and how it is related to solvability of the equation? Is there a nice video/website that anyone can recommend for it?

What is the advantage of non-negative matrix factorization over matrix factorization without the constraint?

This video was the what I need, subbed! (I'm the 666th sub)
