Webinar | Recommender Systems: Using Fuzzy Fingerprints for “Proper” Recommendations by Prof Joao Paulo Carvalho

Abstract: Most Recommender Systems rely exclusively on ratings and are known as Memory-based Collaborative Filtering systems.  This is the currently dominant approach outside of academia due to the low implementation effort and service maintenance, when compared with more complex Model-based approaches.

Computational Intelligence Society

Traditional Memory-based systems have as their main goal to predict ratings, using similarity metrics to determine similarities between the users’ (or items) rating patterns. In this talk, we propose item and user-based Fuzzy Collaborative Filtering approaches that do not necessarily rely on rating prediction, instead leveraging on Fuzzy Fingerprints to create a novel similarity based recommendation approach. Fuzzy Fingerprints provide a concise and compact representation of users allowing the reduction of the dimensionality usually associated with user-based collaborative filtering.
