Prediction Method for Ocean Wave Height Based on Stacking Ensemble Learning Model

open access: yesJournal of Marine Science and Engineering, 2022
Wave heights are important factors affecting the safety of maritime navigation. This study proposed a stacking ensemble learning method to improve the prediction accuracy of wave heights. We analyzed the correlation between wave heights and other oceanic

Stacking-based and improved convolutional neural network: a new approach in rice leaf disease identification

open access: yesFrontiers in Plant Science, 2023
Rice leaf diseases are important causes of poor rice yields, and accurately identifying diseases and taking corresponding measures are important ways to improve yields. However, rice leaf diseases are diverse and varied; to address the low efficiency and

Improving Parcel-Level Mapping of Smallholder Crops from VHSR Imagery: An Ensemble Machine-Learning-Based Framework

open access: yesRemote Sensing, 2021
Explicit spatial information about crop types on smallholder farms is important for the development of local precision agriculture. However, due to highly fragmented and heterogeneous cropland landscapes, fine-scale mapping of smallholder crops, based on

Prediction of maximum scour depth in river bends by the Stacking model

open access: yesJournal of Hydroinformatics, 2023
The accurate prediction of maximum erosion depth in riverbeds is crucial for early protection of bank slopes. In this study, K-means clustering analysis was used for outlier identification and feature selection, resulting in Plan 1 with six influential ...

Cloud-Based Quad Deep Ensemble Framework for the Detection of COVID-19 Omicron and Delta Variants

open access: yesDiagnostics, 2023
The mortality rates of patients contracting the Omicron and Delta variants of COVID-19 are very high, and COVID-19 is the worst variant of COVID. Hence, our objective is to detect COVID-19 Omicron and Delta variants from lung CT-scan images.

Reinterpreting π-stacking [PDF]

open access: yesPhysical Chemistry Chemical Physics, 2020
Examination of the question “is π-stacking a unique form of dispersion?” reveals that planarity, rather than aromaticity per se , facilitates especially strong interactions between polycyclic aromatic hydrocarbons.

A Systematic Evaluation of Ensemble Learning Methods for Fine-Grained Semantic Segmentation of Tuberculosis-Consistent Lesions in Chest Radiographs

open access: yesBioengineering, 2022
Automated segmentation of tuberculosis (TB)-consistent lesions in chest X-rays (CXRs) using deep learning (DL) methods can help reduce radiologist effort, supplement clinical decision-making, and potentially result in improved patient treatment.

Stack-sorting with consecutive-pattern-avoiding stacks [PDF]

open access: yesAdvances in Applied Mathematics, 2021
We introduce consecutive-pattern-avoiding stack-sorting maps $\text{SC}_σ$, which are natural generalizations of West's stack-sorting map $s$ and natural analogues of the classical-pattern-avoiding stack-sorting maps $s_σ$ recently introduced by Cerbai, Claesson, and Ferrari.

Stack sorting with restricted stacks [PDF]

open access: yesJournal of Combinatorial Theory, Series A, 2020
The (classical) problem of characterizing and enumerating permutations that can be sorted using two stacks connected in series is still largely open. In the present paper we address a related problem, in which we impose restrictions both on the procedure and on the stacks.
