Generalizing to Unseen Entities and Entity Pairs with Row-less Universal Schema (2016, methodology): “Riedel et al. (2010) used a relaxation of distant supervision training where all sentences for an entity pair (bag) are considered jointly and only the most relevant sentence is treated as the single training example for the bag’s label.”
Recommender systems survey (2013, background): “The new item problem [174,172] arises because the new items entered in RS do not usually have initial ratings, and therefore, they are not likely to be recommended.”
Functional matrix factorizations for cold-start recommendation (2011, background): “The content features can be used to capture the similarities between users and items and thus reduce the amount of data required to make accurate predictions [2,3,10,15,23,25].”
Inferring Networks of Substitutable and Complementary Products (2015, background): “Although it is promising that we are able to recommend substitutes and complements from the text of product reviews, an obvious question remains as to what can be done for new products, that do not yet have any reviews associated with them, known as the ‘cold-start’ problem in recommender systems [1”
Alors: An algorithm recommender system (2017, unknown): “When it is the case, CF successfully handles the so-called cold-start task (Ahn, 2008; Park and Chu, 2009; Liu et al., 2014): emitting recommendations for a brand new user or selecting algorithms for a brand new problem instance.”
Current challenges and visions in music recommender systems research (2017, methodology): “e recommendations. „is metric has originally been proposed to evaluate e‡ectiveness of information retrieval systems [94]. It is nowadays also frequently used for evaluating music recommender systems [120, 139, 185]. Assuming that the recommendations for user u are sorted according to the predicted ”
