Talk Title: Factorizing Matrices with Missing Entries: Alternative Approaches
Speaker: Prof. Charles Elkan
The known algorithms for approximate
factorization of large matrices are so diverse that the multiple approaches have
never been explained in one place,
and have never been fully compared experimentally. I will outline the available alternatives, focusing especially on experimental results, on methods for factorizing matrices with unknown entries, and on methods based on stochastic gradient descent.
