   Master-uppsats, KTH/Optimeringslära och systemteori

   Författare :Seif Hussein; [2023]
   Nyckelord :Applied mathematics; optimization; convex optimization; matrix factorization; sparse matrix factorization; distributed computing; linearly separable distributed computing; ADMM; alternating direction method of multipliers; tillämpad matematik; optimering; konvex optimering; matrisfaktorisering; gles matrisfaktorisering; distribuerade beräkningar; admm; alternating direction method of multipliers;

   Sammanfattning : 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.

3. 2. Building a Sporting Goods Recommendation System

   Master-uppsats, KTH/Skolan för datavetenskap och kommunikation (CSC)

   Författare :Mikael Flodman; [2015]
   Nyckelord :Recommendation System; ALS-WR; Implicit Data;

   Sammanfattning : This thesis report describes an attempt to build a recommender system for recommending sporting goods in an e-commerce setting, using the customer purchase history as the input dataset. Two input datasets were considered, the item purchases dataset and the item-category dataset. LÄS MER
