I have a similariy matrix that looks like this:
I have a bunch of user vectors with 1s and 0s, with a 1 indicating that someone has clicked on an email (as part of a campaign) and zero to indicate they haven't. Implicit ratings as I have come to understand them.
In terms of an approach, after researching different options, it would appear that the best algorithm to start with a is a matrix-factorisation approach. My question is: what is the best algorithm to start as a baseline model for this type of problem? Any advice on potential pitfalls. Any help would be appreciated. Thanks!
