GA-stacking: Evolutionary stacked generalization [PDF]

open access: yesIntelligent Data Analysis, 2010
Stacking is a widely used technique for combining classifiers and improving prediction accuracy. Early research in Stacking showed that selecting the right classifiers, their parameters and the meta-classifiers was a critical issue. Most of the research on this topic hand picks the right combination of classifiers and their parameters.

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.

A Comparison Study of Roseolumiflavin Solvates: Structural and Energetic Perspective on Their Stability

open access: yesCrystals, 2023
Roseolumiflavin is a deep red microcrystalline derivative of isoalloxazine that exhibits a weak photophysical activity in the solid state. In aqueous as well as in acidic solution of formic or acetic acid, respectively, it tends to form solvates. Herein,

Dynamic Mechanical Strength Prediction of BFRC Based on Stacking Ensemble Learning and Genetic Algorithm Optimization

open access: yesBuildings, 2023
Split Hopkinson pressure bar (SHPB) tests are usually used to determine the dynamic mechanical strength of basalt-fiber-reinforced concrete (BFRC), but this test method is time-consuming and expensive.

Adjectives in Heritage Spanish

open access: yesIsogloss, 2021
Ordering of predicative adjectives within the Noun Phrase varies cross linguistically in systematic ways (Cinque 2010). In Spanish adjectival ordering exhibits more flexibility than in English.

Stratifying Quotient Stacks and Moduli Stacks [PDF]

open access: yes, 2018
Recent results in geometric invariant theory (GIT) for non-reductive linear algebraic group actions allow us to stratify quotient stacks of the form [X/H], where X is a projective scheme and H is a linear algebraic group with internally graded unipotent radical acting linearly on X, in such a way that each stratum [S/H] has a geometric quotient S/H ...

Experimental and Numerical Analysis of Woven Bamboo and Jute Fiber Reinforced in Epoxy Composites [PDF]

open access: yesMechanics of Advanced Composite Structures
Aerospace, transportation, marine, and space applications demand structural materials with low densities yet strong, hard, and high impact strength. Composites are materials that satisfy the needs of recent technology.
