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.

Stylometric relevance-feedback towards a hybrid book recommendation algorithm

TL;DR: It is demonstrated that writing style influences book selection; that book content, characterized with writing style, can be used to improve collaborative filtering results; and that negative examples do not improve final predictions.

A Novel Classification Framework for Evaluating Individual and Aggregate Diversity in Top-N Recommendations

TL;DR: It is found that in contradiction to common assumptions, not all users suffer as expected from the data sparsity problem and the group of users that receive the most accurate recommendations do not belong to the least sparse area of the dataset.

Expectation-Maximization collaborative filtering with explicit and implicit feedback

TL;DR: A novel method, Expectation-Maximization Collaborative Filtering (EMCF), based on matrix factorization, which combines explicit and implicit feedback together in EMCF to infer users' preferences by learning latent factor vectors from Matrix factorization.

Recommender Systems in Antiviral Drug Discovery

TL;DR: RS methods for the prediction of the antiviral activity class (active/inactive) for compounds extracted from ChEMBL achieved relatively good prediction quality for binary classification of individual interactions and compound profiles, as quantified by cross-validation and external validation receiver operating characteristic (ROC) score.

Latent dirichlet allocation

TL;DR: This work proposes a generative model for text and other collections of discrete data that generalizes or improves on several previous models including naive Bayes/unigram, mixture of unigrams, and Hofmann's aspect model.

Latent Dirichlet Allocation

TL;DR: This paper proposed a generative model for text and other collections of discrete data that generalizes or improves on several previous models including naive Bayes/unigram, mixture of unigrams, and Hof-mann's aspect model, also known as probabilistic latent semantic indexing (pLSI).

Some methods for classification and analysis of multivariate observations

TL;DR: The k-means algorithm as mentioned in this paper partitions an N-dimensional population into k sets on the basis of a sample, which is a generalization of the ordinary sample mean, and it is shown to give partitions which are reasonably efficient in the sense of within-class variance.
