Bregman–Hausdorff Divergence: Strengthening the Connections Between Computational Geometry and Machine Learning

Machine Learning and Knowledge Extraction
The purpose of this paper is twofold. On a technical side, we propose an extension of the Hausdorff distance from metric spaces to spaces equipped with asymmetric distance measures.

Regularised transfer learning for hyperspectral image classification

IET Computer Vision, 2019
This study presents a transfer learning method for addressing the insufficient sample problem in hyperspectral image classification. In order to find common feature representation for both the source domain and target domain, we introduce a ...

Habitat loss reshuffles ecological and evolutionary interactions in a seed dispersal network

Oikos, EarlyView.
In tropical forests, habitat loss reshapes species composition, favoring generalists and recently emerged lineages while specialists and older evolutionary lineages are lost. However, how changes in species ecological attributes and evolutionary history affect ecological processes is poorly explored.

Navigating Between the Scylla and Charybdis of Hype and Fear: Decolonizing ELT Materials Through Generative Artificial Intelligence

TESOL Quarterly, EarlyView.
Abstract Despite calls from critical applied linguists to decolonize ELT materials that reproduce colonial ideologies, teachers working under neoliberal constraints and attendant time pressures often have to deliver textbook content as is rather than revising it.

On a Generalization of the Jensen–Shannon Divergence and the Jensen–Shannon Centroid

Entropy, 2020
The Jensen−Shannon divergence is a renown bounded symmetrization of the Kullback−Leibler divergence which does not require probability densities to have matching supports. In this paper, we introduce a vector-skew generalization of the scalar

The link between colorfulness and extinction risk across the world's passerine birds

Conservation Biology, EarlyView.
Abstract Many of the functional traits that mediate extinction risk across the range of biodiversity relate indirectly to a species’ ability to persist in a changing world, yet certain traits such as coloration directly affect human interactions with wildlife.

Non-Extensive Entropic Distance Based on Diffusion: Restrictions on Parameters in Entropy Formulae

Entropy, 2016
Based on a diffusion-like master equation we propose a formula using the Bregman divergence for measuring entropic distance in terms of different non-extensive entropy expressions. We obtain the non-extensivity parameter range for a universal approach to
