Optimising Performance Curves for Ensemble Models through Pareto Front Analysis of the Decision Space

Expert Systems, Volume 42, Issue 7, July 2025.
ABSTRACT Receiver operating characteristic curves are commonly used to evaluate the performance of machine learning ensemble classification models that combine multiple classifiers through a voting procedure. Although these models have many parameters, standard ROC analyses typically vary only the voting threshold, limiting their potential for ...

Correlation networks in economics and finance: A review of methodologies and bibliometric analysis

Journal of Economic Surveys, Volume 39, Issue 3, Page 1252-1286, July 2025.
Abstract This paper presents an in‐depth review of the methodologies and innovations in the study of correlation networks in economics and finance. We explore the development of filtering algorithms and distance measures, emphasizing their critical role in extracting meaningful financial interconnections.

Enantioselective Photochemical Generation of a Short‐Lived, Twisted Cycloheptenone Isomer: Catalytic Formation, Detection, and Consecutive Chemistry

Angewandte Chemie, Volume 137, Issue 23, June 2, 2025.
In a proof‐of‐concept study, it was for the first time shown that planar chiral trans‐cycloalk‐2‐enones, such as 2, can be formed enantioselectively from their cis‐isomers by triplet energy transfer from a chiral catalyst. Computational studies performed with cyclohept‐2‐enone and enone 1 provided invaluable insights into the mode of action of the ...

Evolutionary history, novel lineages and symbiont coevolution in the ant tribe Camponotini (Hymenoptera: Formicidae)

Systematic Entomology, Volume 50, Issue 3, Page 646-676, July 2025.
Phylogenomic data illuminate the evolutionary history of the ant tribe Camponotini and its obligate bacterial endosymbiont, Blochmannia, and suggest a Paleotropical Eocene origin of the association. We discover three novel lineages of camponotine ants, previously misidentified as members of the large cosmopolitan genus Camponotus.
