Scalable Variational Gaussian Processes for Crowdsourcing: Glitch Detection in LIGO
TL;DR: This first approach, which is referred to as scalable variational Gaussian processes for crowdsourcing (SVGPCR), brings back GP-based methods to a state-of-the-art level, and excels at uncertainty quantification.
Proceedings Article
An automated system for visual biometrics
TL;DR: A system capable of automatically extracting visual feature s from a human face for use in dynamic visual biometrics is described, which incorporates robust and efficient vision algorithms to automatically detect, track and identify a speaker based on visual feature extracted from the speaker’s mouth region.
Journal ArticleDOI
Decision-aided compensation of severe phase-impairment-induced inter-carrier interference in frequency-selective OFDM
TL;DR: A new, reduced complexity algorithm is proposed for compensating the Inter-Carrier Interference (ICI) caused by severe PHase Noise and Residual Frequency Offset in OFDM systems.
Proceedings ArticleDOI
A general formulation of the weighted smoothing functional for regularized image restoration
TL;DR: A general form of the weighted smoothing functional for regularized image restoration is proposed, defined as a function of the (partially) restored image, which is nonlinear with respect to the unknown image.
Proceedings Article
Laplacian sift in visual search
TL;DR: This work presents a SIFT descriptor dimension reduction scheme based on Laplacian Graph Embedding, which computes a linear embedding that preserves the topological relationship among visual descriptors.
