This paper presents probabilistic matrix factorization (PMF), an efficient algorithm for collaborative filtering that leverages stochastic gradient descent (SGD) in order to scale better than previous algorithms which use Expectation-Maximization (EM). This paper also compares PMF's performance against three other collaborative filtering algorithms: matrix factorization using EM (MF-EM), stochastic matrix factorization (SMF), singular value decomposition (SVD), and non-negative matrix factorization (NMF). PMF is shown through experimentation on two real-world datasets (texttt{ml-100k} from GroupLens Research~cite{groupLens} which contains movie ratings from 943 users on 1682 movies collected between September 19th 1997 - March 31st 1998)~cite{movielens}, texttt{ml-10M100K} from GroupLens Research~cite{groupLens} which contains movie ratings from 69878 users on 10681 movies collected between January 09th 1995 - March 31st 2015)~cite{movielens}, texttt{jester}, which contains ratings from $>$20 million users)~cite{jester} that it performs better than MF-EM or SMF at both low-rank approximations ($k leqslant$10) or high-rank approximations ($k geqslant$10). It also outperforms NMF at low-rank approximations but does not scale as well as SVD at high-rank approximations. noindent {bf Introduction}: This paper explores collaborative filtering techniques that use matrix factorization as well as one that uses singular value decomposition (SVD) in order to produce recommendations based on past user-item interactions. In particular we focus on three collaborative filtering techniques: probabilistic matrix factorization (PMF), stochastic matrix factorization (SMF), matrix factorization using Expectation-Maximization (MF-EM), as well as two baseline methods: singular value decomposition (SVD)~cite{singularValueDecomposition}~cite{singularValueDecompositionRefined}~cite{singularValueDecompositionWithSideInformation}~cite{singularValueDecompositionRise}~cite{singularValueDecompositionNMF}, non-negative matrix factorization (NMF). In Section~ref{sec:pmf}, we explore PMF which uses SGD for optimization instead of EM like MF-EM. We show that PMF has better convergence properties than MF-EM because it uses mini-batch SGD instead of EM which uses batch gradient descent at each iteration. In Section~ref{sec:smf}, we explore SMF which also uses SGD but does not use mini-batches like PMF does instead it samples one data point at each iteration. We show that PMF converges faster than SMF because it uses mini-batches instead of sampling one data point at each iteration. In Section~ref{sec:svd}, we explore SVD which also uses SGD but does not use mini-batches like PMF does instead it samples one data point at each iteration. We show that SVD scales better than PMF because it does not have any latent factors unlike PMF which has latent factors $k$. In Section~ref{sec:nmf}, we explore NMF which also uses SGD but does not use mini-batches like PMF does instead it samples one data point at each iteration. We show that PMF outperforms NMF at low-rank approximations ($k leqslant$10) but NMF scales better than PMF at high-rank approximations ($k geqslant$10). In Section~ref{sec:experiments}, we present our experiments on two real-world datasets (texttt{ml-100k} from GroupLens Research~cite{groupLens} which contains movie ratings from 943 users on 1682 movies collected between September 19th 1997 - March 31st 1998)~cite{movielens}, texttt{ml-10M100K} from GroupLens Research~cite{groupLens} which contains movie ratings from 69878 users on 10681 movies collected between January 09th 1995 - March 31st 2015)~cite{movielens}, texttt{jester}, which contains ratings from $>$20 million users)~cite{jester}. Our results show that PMF outperforms all other algorithms at low-rank approximations ($k leqslant$10). At high-rank approximations ($k geqslant$10), SVD scales better than all other algorithms but PMF still outperforms all other algorithms except SVD. noindent {bf Related Work}: In this section we discuss some previous work related to collaborative filtering using matrix factorization techniques. In Chapter~4 of ``Machine Learning'' by Kevin P. Murphy~cite{machineLearningBook}, he discusses probabilistic matrix factorization (PMF) which is defined by maximizing this log likelihood function:

L(Theta)= sum_{(u,i)in{cal D}} log p(r_{ui}|u,i;Theta)+ log p(u;Theta)+ log p(i;Theta)
= sum_{(u,i)in{cal D}} (log N(r_{ui}|g_u^Tu_i,sigma^2)+ log N(g_u|mu_g,Lambda_g^{-1})+log N(g_i|mu_i,Lambda_i^{-1}))
= sum_{(u,i)in{cal D}} (log N(r_{ui}|g_u^Tu_i,sigma^2)- frac12 g_u^TSigma_gg_u-frac12 g_i^TSigma_ig_i-frac12(g_u-mu_g)^TS_g(g_u-mu_g)- frac12(g_i-mu_i)^TS_ig_i+c)
