The neurophysiological basis of optimism bias

2020
Optimism bias describes people’s tendency to overestimate their likelihood of experiencing positive events and underestimate their likelihood of experiencing negative events in the future. The present chapter provides the necessary theoretical background to understand the various facets of optimism bias (section “Introduction”) and depicts multiple ...

Risk and Bias in Portfolio Optimization

2020
In this paper we derive weighted squared risk measures for a commonly used Stein-type estimator of the global minimum variance portfolio. The risk functions are conveniently split in terms of variance and squared bias over different weight matrices. It is argued that the common out-of-sample variance criteria should be used with care and that a simple ...

Optimization of Bias in Thermistor Radiation Detectors II: Practical Bias Networks

Applied Optics, 1969
Bridge bias networks with better performance than those of Part I are introduced. Linear equations for bridge null changes caused by ambient temperature and bias voltage variations are presented. They are discussed in relation to direct coupling.

The Nth-Bias and Blackwell Optimality

2020
In a Markov chain, an th bias is the bias of an Nth bias,. with 1st bias being the standard bias. The Nth biases measure the transient performance of the Markov chain at different levels. In this chapter, we study the optimization problems of the Nth biases for time-nonhomogeneous Markov chains (TNHMCs).

Body bias optimization for variable pipelined CGRA

2017 27th International Conference on Field Programmable Logic and Applications (FPL), 2017
Variable Pipeline Cool Mega Array (VPCMA) is an low power Coarse Grained Reconfigurable Architecture (CGRA) based on the concept of CMA (Cool Mega Array). It implements a pipeline structure that can be configured depending on performance requirements, and the silicon on thin buried oxide (SOTB) technology that allows to control its body bias voltage to

The Optimism Bias and Traffic Safety

Proceedings of the Human Factors Society Annual Meeting, 1987
In this study, college students were asked to rate their overall accident likelihood, driving skill, and level of safety relative to other drivers. They also made comparative risk judgements for a variety of specific accident situations. Consistent with previous research, subjects perceived themselves as safer, more skillful, and less likely to be ...

Optimal bounds on the bias of quasimidranges

Statistics, 2014
We derive sharp upper and lower bounds on expectations of sample quasimidranges, that is, arithmetic means of two fixed order statistics of the sample, expressed in various scale units. They can be considered as the bounds on the bias of estimating unknown mean of the parent distribution by the above statistics.
