An alternating sign matrix (ASM) is a square matrix in which each entry is -1, 0 or 1, and along each row and column the nonzero entries alternate in sign, starting and ending with a 1. This talk will ...

In this lesson, we will look at another matrix factorization technique called Alternating Least Squares (ALS). This method can prove to be much more effective and robust than the SVD we saw earlier.
