Abstract:Recommender systems are crucial tools used in most of daily-based web applications. Matrix factorization is an advanced and efficient technique for recommender systems. Recently, Stochastic Gradient Descent (SGD) method is considered to be one of the most popular techniques for matrix factorization. SGD is a sequential algorithm, which is difficult to be parallelized for largescale problems. Nowadays, researches focus on efficiently parallelizing SGD. In this research, we propose a novel GPU approach for paral… Show more
