Project Report An Introduction to Collaborative Filtering

چکیده
A Collaborative Filtering was successfully implemented using the computer programming language Java to produce recommendations between users such that only similar users were considered. Both Mean Squared Difference (MSD) and Pearson Correlation Coefficient (PCC) were used and evaluations carried out on each. The metric which performed best on the u.data file was PCC with L = 0. Conversely, the metric which perfomed best on the u-filtered.data file was MSD with L = 2 and L = 3.
