EigenPrism:Inference for High-Dimensional Signal-to-Noise Ratios
EigenPrism High-Dimensional Signal Noise Ratios
2015/6/17
Consider the following three important problems in statistical inference, namely, constructing confidence intervals for (1) the error of a high-dimensional (p > n) regression estimator, (2) the linear...

Image authentication has applications in security systems, photo forensics, and photo journalism. This paper presents an image authentication scheme using added signal-dependent noise. Imperceptible n...
Discerning a Signal from Noise: The Discovery of Weak Neutral Currents reconsidered
high energy physics discovery of Weak Neutral Currents
2008/4/11
In this paper I try to shed some light on how one discerns a physical ‘signal’ from ‘noise’ in experimental science. To this end I revisit the discovery of Weak Neutral Currents (WNC), on which some o...

Study on high signal-to-noise ratio (SNR) silicon p-n junction photodetector
silicon p-n junction photodetector
2011/5/3
On the basis of n-type single-crystal (100) silicon substrate, a silicon p-n junction photodetector has been successfully developed. Three methods to improve photoresponse signal-to-noise ratio (SNR) ...
Evaluation of hydrological models for scenario analyses:signal-to-noise-ratio between scenario effects and model uncertainty
hydrological models scenario analyses signal-to-noise-ratio scenario effects model uncertainty
2010/1/25
Many model applications suffer from the fact that although it is well known that model application implies different sources of uncertainty there is no objective criterion to decide whether a model is...
Small-Signal and Noise Model Determination for Double Polysilicon Self-Aligned Bipolar Transistors
Noise Model Determination Double Polysilicon Self-Aligned Bipolar Transistors
2010/12/14
In this paper, noise characterization and modeling of a double polysilicon self-aligned bipolar transistor are presented. The device has been characterized in terms of noise and scattering parameters ...
