System and method for using noisy collaborative filtering to rank and present items |
摘要 |
<p>A system and method of providing predicted user ratings includes calculating the accuracy of predictions based on the variance of distribution of the predicted user's rating. The system and method present and rank the results by treating the variance as a source of noise. The decision to present or not to present an item is made by sampling the probability distribution of the predicted rating and comparing the result to some user-set threshold (e.g., "show me all results that the system predicts I will score 3 or higher") or a system default value. <IMAGE></p> |
