Hi Jake and Ted, Thanks a lot for your feedback. I'll refocus my proposal on implementing RBM for the Netflix dataset(there is some parallelization opportunity, I'm working on figuring out the details). This would add in a new RBM algorithm, as well as provide the hooks required for rapid iteration of an ensemble approach for Netflix using already implemented algorithms. As Ted mentioned, I'll also account for documentation and other associated works in the timeline in the final proposal.
I'll do some more ground work at the algorithm and code level, and update on the list with any queries that I have. Please do give any other feedback that you think is relevant.
