What is the Dimension of Your Binary Data
TL;DR: In this paper, the concept of normalized fractal dimension is introduced to measure the degree of dependency structure of the data and the properties of such a dimension are discussed and compared with PCA.
Proceedings ArticleDOI
Listwise Collaborative Filtering
TL;DR: This paper proposes a new ranking-oriented CF algorithm, called ListCF, which directly predicts a total order of items for each user based on similar users' probability distributions over permutations of the items, and thus differs from previous ranking- oriented memory-based CF algorithms that focus on predicting the pairwise preferences between items.

Cyberphysical System With Virtual Reality for Intelligent Motion Recognition and Training
TL;DR: This paper proposes to build a comprehensive cyberphysical system (CPS) with virtual reality (VR) and intelligent sensors for motion recognition and training and uses both wearable wireless sensors and nonintrusive wireless sensors to monitor the motion training status.
Journal ArticleDOI
An Exemplar-Based Approach to Frequency Warping for Voice Conversion
TL;DR: A new voice conversion framework is presented in which frequency warping and exemplar-based method for voice conversion is combined and a significant improvement in speech quality is observed over the state-of-the-art parametric methods.
