Some results on quadratic credibility premium using the balanced loss function [PDF]

open access: yesArab Journal of Mathematical Sciences, 2023
Purpose – This paper generalizes the quadratic framework introduced by Le Courtois (2016) and Sumpf (2018), to obtain new credibility premiums in the balanced case, i.e. under the balanced squared error loss function.

Balanced Loss Function for Accurate Surface Defect Segmentation

open access: yesApplied Sciences, 2023
The accurate image segmentation of surface defects is challenging for modern convolutional neural networks (CNN)-based segmentation models. This paper identifies that loss imbalance is a critical problem in segmentation accuracy improvement.

Stein-Rule Estimation under an Extended Balanced Loss Function [PDF]

open access: yesJournal of Statistical Computation and Simulation, 2007
This paper extends the balanced loss function to a more general set up. The ordinary least squares and Stein-rule estimators are exposed to this general loss function with quadratic loss structure in a linear regression model.

Breakpoint-resolved balanced t(2;12)(q35;q24.31) disrupting HNF1A in multigenerational MODY-3: Diagnostic utility of long-read genome sequencing and therapeutic impact [PDF]

open access: yesMetabolism Open
Balanced translocations that interrupt HNF1A are seldom documented in MODY-3. We studied a three-generation family with early-onset, non-autoimmune diabetes consistent with MODY-3.

IoU-Balanced loss functions for single-stage object detection [PDF]

open access: yesPattern Recognition Letters, 2022
Single-stage object detectors have been widely applied in computer vision applications due to their high efficiency. However, we find that the loss functions adopted by single-stage object detectors hurt the localization accuracy seriously. Firstly, the standard cross-entropy loss for classification is independent of the localization task and drives ...

Nonlinear Programming to Determine Best Weighted Coefficient of Balanced LINEX Loss Function Based on Lower Record Values

open access: yesComplexity, 2021
Majority research studies in the literature determine the weighted coefficients of balanced loss function by suggesting some arbitrary values and then conducting comparison study to choose the best.

Estimating Two Parameters of Lomax Distribution by Using the Upper Recorded Values under Two Balanced Loss Functions [PDF]

open access: yesالمجلة العراقية للعلوم الاحصائية, 2019
In this paper, two lomax distribution parameters are estimated along with the estimation of the reliability function under two balanced loss functions: the balanced squared error function and balanced linex loss function.

Comparison of Risk Ratios of Shrinkage Estimators in High Dimensions

open access: yesMathematics, 2021
In this paper, we analyze the risk ratios of several shrinkage estimators using a balanced loss function. The James–Stein estimator is one of a group of shrinkage estimators that has been proposed in the existing literature.
