Modeling pathological speech perception from data with similarity labels
TL;DR: This work proposes new cost functions for examining data from a series of experiments, whereby it asks certified SLPs to rate pathological speech along the perceptual dimensions that contribute to decreased intelligibility, and develops objective measures of the speech signal degradation that correlate well with SLP responses.
Proceedings ArticleDOI
Bayesian Optimization in High-Dimensional Spaces: A Brief Survey
TL;DR: In this paper, the authors present a review of the methods that exploit different underlying structures on the objective function to scale Bayesian optimization to high dimensions, in particular, they focus on the techniques that exploit the structure of the objective functions.
Proceedings ArticleDOI
Distributed estimation over fading macs with multiple antennas at the fusion center
TL;DR: It is shown that though there is benefit in having multiple antennas at the fusion center, when full channel information is available at the sensors, the gain in performance is at most a factor of 2.
Journal ArticleDOI
Performance of precoded OFDM with channel estimation error
TL;DR: The proposed optimal power allocation scheme based on the derived PEP has performance that converges to the performance with perfect channel state information when the number of subcarriers to the channel length ratio increases.
Proceedings ArticleDOI

TL;DR: The study describes remote fault detection using machine learning approaches, power output optimization using cloud movement prediction and consensus-based solar array parameter estimation, which are used in the development of a utility-scale solar cyber-physical system.
