Abstract
As one of the most successful approaches to building recommender systems, collaborative filtering (CF) uses the known preferences of a group of users to make recommendations or predictions of the unknown preferences for other users. In this paper, we first introduce CF tasks and their main challenges, such as data sparsity, scalability, synonymy, gray sheep, shilling attacks, privacy protection, etc., and their possible solutions. We then present three main categories of CF techniques: memory-based, modelbased, and hybrid CF algorithms (that combine CF with other recommendation techniques), with examples for representative algorithms of each category, and analysis of their predictive performance and their ability to address the challenges. From basic techniques to the state-of-the-art, we attempt to present a comprehensive survey for CF techniques, which can be served as a roadmap for research and practice in this area.

TRY - a global database of plant traits

Jens Kattge, +136 more
TL;DR: TRY as discussed by the authors is a global database of plant traits, including morphological, anatomical, physiological, biochemical and phenological characteristics of plants and their organs, which can be used for a wide range of research from evolutionary biology, community and functional ecology to biogeography.

Collaborative recommendation: A robustness analysis

TL;DR: This work analyzes the robustness of collaborative recommendation: the ability to make recommendations despite (possibly intentional) noisy product ratings, and formalizes recommendation accuracy in machine learning terms and develops theoretically justified models of accuracy.

Modeling User Rating Profiles For Collaborative Filtering

TL;DR: A generative latent variable model for rating-based collaborative filtering called the User Rating Profile model (URP), which represents each user as a mixture of user attitudes, and the mixing proportions are distributed according to a Dirichlet random variable.

Collaborative filtering with the simple Bayesian classifier

TL;DR: An approach to collaborative filtering based on the Simple Bayesian Classifier, which calculates the similarity between users from negative ratings and positive ratings separately and shows that one of the proposed Bayesian approaches significandy outperforms a correlation-based collaborative filtering algorithm.

Flexible mixture model for collaborative filtering

TL;DR: FMM extends existing partitioning/clustering algorithms for collaborative filtering by clustering both users and items together simultaneously without assuming that each user and item should only belong to a single cluster.

Probabilistic memory-based collaborative filtering

TL;DR: It is shown that a probabilistic active learning method can be used to actively query the user, thereby solving the "new user problem" of memory-based collaborative filtering.
