Binary Classifier Calibration using an Ensemble of Near Isotonic Regression Models. [PDF]

open access: yesProc IEEE Int Conf Data Min, 2016
Learning accurate probabilistic models from data is crucial in many practical tasks in data mining. In this paper we present a new non-parametric calibration method called \textit{ensemble of near isotonic regression} (ENIR). The method can be considered

Identifying change points in a covariate effect on time-to-event analysis with reduced isotonic regression. [PDF]

open access: yesPLoS ONE, 2014
Isotonic regression is a useful tool to investigate the relationship between a quantitative covariate and a time-to-event outcome. The resulting non-parametric model is a monotonic step function of a covariate X and the steps can be viewed as change ...

Relaxivity of Gadobutrol and Gadoteric Acid in Cerebrospinal Fluid at 3T. [PDF]

open access: yesMagn Reson Med
ABSTRACT Purpose The aim was to estimate T1 relaxivity of gadobutrol and gadoteric acid in cerebrospinal fluid (CSF) at 3T, to support research on CSF‐flow and the glymphatic system in humans utilizing T1 mapping after intrathecal injection. Methods Using a phantom, relaxivity was estimated for gadobutrol and gadoteric acid in lumbar CSF and an ...

A lightweight deep learning framework for reliable microscopy-based diagnosis of cutaneous leishmaniasis. [PDF]

open access: yesPLoS ONE
Cutaneous leishmaniasis (CL) is a neglected tropical and zoonotic disease affecting both human and animal health, for which microscopic examination of Giemsa-stained slides remains the diagnostic reference standard despite being time-consuming and ...

A clinical prediction model for central venous catheter-associated bloodstream infections: derivation and validation from the MIMIC-IV cohort [PDF]

open access: yesEuropean Journal of Medical Research
Background Central venous catheter-associated bloodstream infections (CVC–BSIs) significantly affect clinical outcomes in critically ill patients. Existing risk prediction models lack comprehensive integration of early clinical indicators.

A Meta-Analysis for Simultaneously Estimating Individual Means with Shrinkage, Isotonic Regression and Pretests

open access: yesAxioms, 2021
Meta-analyses combine the estimators of individual means to estimate the common mean of a population. However, the common mean could be undefined or uninformative in some scenarios where individual means are “ordered” or “sparse”.
