A sub-one quasi-norm-based similarity measure for collaborative filtering in recommender systems

Information Sciences, 487, 142–155.

By: S. Jiang n, S. Fang n , Q. An n & J. Lavery n

author keywords: Recommender system; Collaborative filtering; Neighborhood-based CF; Similarity measure; l(p)quasi-norm
TL;DR: A sub-one quasi-norm-based similarity measure for collaborative filtering in a recommender system shows its advantages over those commonly used similarity measures in the literature by making better use of rating values and deemphasizing the dissimilarity between users.

Enhanced linear reformulation for engineering optimization models with discrete and bounded continuous variables

Applied Mathematical Modelling, 58, 140–157.

By: Q. An n, S. Fang n , H. Li * & T. Nie *

author keywords: Nonlinear discrete optimization; Linear reformulation; Polynomial programming; Signomial programming
TL;DR: This paper significantly extends the applicability of state-of-the-art ELDP (equations for linearizing discrete product terms) method by providing a new linearization to handle more complicated non-linear terms involving both of discrete and bounded continuous variables.
