2019 journal article

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.

2016 journal article

On linear conic relaxation of discrete quadratic programs

Optimization Methods and Software, 31(4), 737–754.

By: T. Nie n, S. Fang n , Z. Deng * & J. Lavery n

author keywords: discrete quadratic program; linear conic relaxation; RLT method
TL;DR: A special reformulation-linearization technique based linear conic relaxation is proposed for discrete quadratic programming (DQP) and it is shown that the proposed relaxation is tighter than the traditional positive semidefinite programming relaxation. (via Semantic Scholar)

2013 conference paper

Comparison of an ℓ1-regression-based and a RANSAC-based planar segmentation procedure for urban terrain data with many outliers

In L. Bruzzone (Ed.), Image and Signal Processing for Remote Sensing XIX (p. 889209).

By: J. Luo  n, Z. Deng n, D. Bulatov *, J. Lavery n & S. Fang n 

Ed(s): L. Bruzzone

author keywords: DBSCAN; fuzzy c-means; l(1) regression; outlier-rich; planar; RANSAC; segmentation; urban terrain
TL;DR: The complete building reconstruction procedure into which the ℓ1-regression-based and RANSAC-based segmentation procedures will be integrated in the future is outlined. (via Semantic Scholar)

2012 journal article

Univariate cubic L-1 interpolating splines based on the first derivative and on 5-point windows: analysis, algorithm and shape-preserving properties

COMPUTATIONAL OPTIMIZATION AND APPLICATIONS, 51(2), 575–600.

By: Q. Jin*, L. Yu  n, J. Lavery n & S. Fang n 

author keywords: Cubic L-1 spline; First-derivative-based; Interpolation; Locally calculated; Shape preservation
TL;DR: It is shown that cubic L1 splines based on the first derivative and on 5-point windows preserve linearity of the original data and avoid extraneous oscillation. (via Semantic Scholar)
