Bias reduction in representation of histopathology images using deep feature selection [PDF]

open access: yesScientific Reports, 2022
Appearing traces of bias in deep networks is a serious reliability issue which can play a significant role in ethics and generalization related concerns.

Learning from scanners: Bias reduction and feature correction in radiomics [PDF]

open access: yesClinical and Translational Radiation Oncology, 2019
Purpose: Radiomics are quantitative features extracted from medical images. Many radiomic features depend not only on tumor properties, but also on non-tumor related factors such as scanner signal-to-noise ratio (SNR), reconstruction kernel and other ...

Bias reduction of a conditional maximum likelihood estimator for a Gaussian second-order moving average model

open access: yesModern Stochastics: Theory and Applications, 2021
In this study, we consider a bias reduction of the conditional maximum likelihood estimators for the unknown parameters of a Gaussian second-order moving average (MA(2)) model.

Antithetic Power Transformation in Monte Carlo Simulation: Correcting Hidden Errors in the Response Variable

open access: yesMathematics, 2023
Monte Carlo simulation is performed with uniformly distributed U(0,1) pseudo-random numbers. Because the numbers are generated from a mathematical formula, they will contain some serial correlation, even if very small.

Bias reduction in the logistic model parameters with the LogF(1,1) penalty under MAR assumption

open access: yesFrontiers in Applied Mathematics and Statistics, 2022
In this paper, we present a novel validated penalization method for bias reduction to estimate parameters for the logistic model when data are missing at random (MAR).

A climatological benchmark for operational radar rainfall bias reduction [PDF]

open access: yesHydrology and Earth System Sciences, 2021
The presence of significant biases in real-time radar quantitative precipitation estimations (QPEs) limits its use in hydrometeorological forecasting systems.

Constant and switched bias low frequency noise in p-MOSFETs with varying gate oxide thickness [PDF]

open access: yes, 2002
The low-frequency noise power spectral density of MOSFETs is decreased if the MOSFETs are periodically switched 'off' (switched bias conditions). The influence of the gate oxide thickness on fixed bias and switched biased low frequency drain current ...

Improved the bias in kernel quantile function estimation

open access: yesAIMS Mathematics, 2023
In this paper, a new estimator for kernel quantile estimation is given to reduce the bias. The asymptotic properties of the proposed estimator was established and it turned out that the bias has been reduced to the fourth power of the bandwidth, while ...

The Role of Response Bias in Perceptual Learning [PDF]

open access: yes, 2015
Sensory judgments improve with practice. Such perceptual learning is often thought to reflect an increase in perceptual sensitivity. However, it may also represent a decrease in response bias, with unpracticed observers acting in part on a priori hunches

Improved horizontal installation of large soil moisture content sensors and interpretation of their readings in terms of preferential flow / Zlepšená vodorovná instalace velkých čidel půdní vlhkosti a interpretace jejich čtení ve smyslu preferenčního proudění

open access: yesJournal of Hydrology and Hydromechanics, 2012
Vlhkost hlinité černozemní půdy na karbonátovém sprašovém substrátu byla měřena metodou TDR čidly Aqua-Tel-TDR (Automata, Inc., dnes McCrometer CONNECT).
