Keyword(s): collaborative filtering, skewed dataset, pLSA
Abstract: Many real life datasets have skewed distributions of events when the probability of observing few events far exceeds the others. In this paper, we observed that in skewed datasets the state of the art collaborative filtering methods perform worse than a simple probabilistic model. Our test bench inc ...
