An investigation of thresholds in air pollution-mortality effects [PDF]
, 2004 In this paper we introduce and implement new techniques to investigate threshold effects in air pollution-mortality relationships. Our key interest is in measuring the dose-response relationship above and below a given threshold level where we allow for ...

Average Case Analysis of Multichannel Thresholding [PDF]
2007 IEEE International Conference on Acoustics, Speech and Signal Processing - ICASSP '07, 2007 This paper introduces p-thresholding, an algorithm to compute simultaneous sparse approximations of multichannel signals over redundant dictionaries. We work out both worst case and average case recovery analyses of this algorithm and show that the latter results in much weaker conditions on the dictionary. Numerical simulations confirm our theoretical

Vector Analysis of Threshold Functions
Information and Computation, 1995 The authors study the realizability of Boolean functions using threshold gates. Using several tools from linear algebra they obtain various results concerning this subject (a lower bound for the number of input functions required by a threshold gate implementing a given function, the error incurred when a Boolean function is approximated, results on ...

Threshold selection in univariate extreme value analysis [PDF]
Extremes, 2021 AbstractThreshold selection plays a key role in various aspects of statistical inference of rare events. In this work, two new threshold selection methods are introduced. The first approach measures the fit of the exponential approximation above a threshold and achieves good performance in small samples.

Morphological Component Analysis: An Adaptive Thresholding Strategy [PDF]
IEEE Transactions on Image Processing, 2007 In a recent paper, a method called morphological component analysis (MCA) has been proposed to separate the texture from the natural part in images. MCA relies on an iterative thresholding algorithm, using a threshold which decreases linearly towards zero along the iterations.

Analysis of Slotted ALOHA With an Age Threshold [PDF]
IEEE Journal on Selected Areas in Communications, 2021 We present a comprehensive steady-state analysis of threshold-ALOHA, a distributed age-aware modification of slotted ALOHA proposed in recent literature. In threshold-ALOHA, each terminal suspends its transmissions until the Age of Information (AoI) of the status update flow it is sending reaches a certain threshold $ $. Once the age exceeds $ $, the
