1. A personalization system, comprising:
- a processor; and
a software system executed by the processor;
wherein the software system provides a recommendation for an item, the recommendation based on a comparison of a low-rank approximation of a domain matrix to a user profile, the user profile based, in part, on the low-rank approximation of the domain matrix.

Abstract
A system and method for providing personalized recommendations are disclosed herein. A system includes a processor and a software system executed by the processor. The software system provides a recommendation for an item. The recommendation is based on a comparison of a low-rank approximation of a domain matrix to a user profile. The user profile is based, in part, on the low-rank approximation of the domain matrix.

9. A computer readable medium encoded with a computer program, the computer program comprising:
-
instructions that when executed by a processor compute a low-rank approximation of a matrix representing a domain data set, the approximation matrix having a pre-selected number of dimensions; and instructions that when executed by a processor provide a recommendation for an item, the recommendation based on similarity of the low-rank approximation of the matrix representing the domain data set to a user profile based, in part, on the low-rank approximation of the matrix representing the domain data set. - View Dependent Claims (10, 11, 12, 13, 14, 15)
