1. Minimum Cost Distributed Computing using Sparse Matrix Factorization
University essay from KTH/Optimeringslära och systemteoriAbstract : Distributed computing is an approach where computationally heavy problems are broken down into more manageable sub-tasks, which can then be distributed across a number of different computers or servers, allowing for increased efficiency through parallelization. This thesis explores an established distributed computing setting, in which the computationally heavy task involves a number of users requesting a linearly separable function to be computed across several servers.

5. Matrix factorization in recommender systems : How sensitive are matrix factorization models to sparsity?
University essay from Uppsala universitet/Statistiska institutionenAbstract : One of the most popular methods in recommender systems are matrix factorization (MF) models. In this paper, the sensitivity of sparsity of these models are investigated using a simulation study. Using the MovieLens dataset as a base several dense matrices are created. READ MORE
