Hybrid deep learning and optimized variational mode decomposition for point-interval runoff prediction. [PDF]

open access: yesPLoS ONE
Runoff prediction is crucial for water resource allocation and hydropower planning. To address low accuracy and uncertainty in runoff forecasting, this study proposes a framework integrating the Information Acquisition Optimizer (IAO), Variational Mode ...

Application of Mazur–Orlicz's theorem in AMISE calculation [PDF]

open access: yesApplicationes Mathematicae, 2002
Summary: An approximation error and an asymptotic formula are given for shift invariant operators of polynomial order~\(\varrho\). Density estimators based on shift invariant operators are introduced and AMISE is calculated.

Local Linear Regression Estimator on the Boundary Correction in Nonparametric Regression Estimation

open access: yesJournal of Statistical Theory and Applications (JSTA), 2020
The precision and accuracy of any estimation can inform one whether to use or not to use the estimated values. It is the crux of the matter to many if not all statisticians.

On the fourth-order hybrid beta polynomial kernels in kernel density estimation

open access: yesJournal of Nigerian Society of Physical Sciences
This paper introduces a novel family of fourth-order hybrid beta polynomial kernels tailored for statistical analysis. The efficacy of these kernels is evaluated using two principal performance metrics: asymptotic mean integrated squared error (AMISE ...

Non-parametric statistical approach for assessing the environmental impacts of petroleum spillages in the Niger Delta region of Nigeria

open access: yesDiscover Environment
Petroleum spillages (PTS) have significantly contributed to environmental degradation in Nigeria’s Niger Delta Region (NDR). This research aims to establish the causes of PTS in the NDR using nonparametric statistical methods for five years.

TAKDE: Temporal Adaptive Kernel Density Estimator for Real-Time Dynamic Density Estimation [PDF]

open access: yesIEEE Transactions on Pattern Analysis and Machine Intelligence, 2022
Real-time density estimation is ubiquitous in many applications, including computer vision and signal processing. Kernel density estimation is arguably one of the most commonly used density estimation techniques, and the use of “sliding window” mechanism

Kernel density estimation with linked boundary conditions [PDF]

open access: yesStudies in applied mathematics (Cambridge), 2018
Kernel density estimation on a finite interval poses an outstanding challenge because of the well‐recognized bias at the boundaries of the interval. Motivated by an application in cancer research, we consider a boundary constraint linking the values of ...
