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.

Stack Sorting with Increasing and Decreasing Stacks [PDF]

open access: yesThe Electronic Journal of Combinatorics, 2020
We introduce a sorting machine consisting of $k+1$ stacks in series: the first $k$ stacks can only contain elements in decreasing order from top to bottom, while the last one has the opposite restriction. This device generalizes the $\mathfrak{DI}$ machine introduced by Rebecca Smith, which studies the case $k=1$.

Research on Strawberry Quality Grading Based on Object Detection and Stacking Fusion Model

open access: yesIEEE Access, 2023
Strawberry quality grading helps producers to better manage inventory, transportation and sales, and improve product market competitiveness. Currently, this work is mostly carried out by manual grading, which is not only inefficient, but also relies on ...

A stacking ensemble algorithm for improving the biases of forest aboveground biomass estimations from multiple remotely sensed datasets

open access: yesGIScience & Remote Sensing, 2022
Accurately quantifying the aboveground biomass (AGB) of forests is crucial for understanding global change-related issues such as the carbon cycle and climate change.

Comparing Stacking Ensemble Techniques to Improve Musculoskeletal Fracture Image Classification

open access: yesJournal of Imaging, 2021
Bone fractures are among the main reasons for emergency room admittance and require a rapid response from doctors. Bone fractures can be severe and can lead to permanent disability if not treated correctly and rapidly.
