Oikos, EarlyView.Accurate functional trait data are essential for understanding ecosystem services and processes in fragmented landscapes. We evaluated whether the global EltonTraits 1.0 database adequately represents the functional structure of mammal communities in forest fragments and restoration sites in a highly fragmented Atlantic Forest landscape.

Modified Jensen-Bregman LogDet Divergence for Target Detection With Region Covariance Descriptor
IEEE AccessIn this study, we exploit the modified Jensen-Bregman LogDet (MJBLD) divergence to measure the dissimilarity between two region covariance descriptors extracted from an image, and design a target detection method based on this descriptor.

Information Geometric Approach on Most Informative Boolean Function Conjecture
Entropy, 2018 Let X n be a memoryless uniform Bernoulli source and Y n be the output of it through a binary symmetric channel. Courtade and Kumar conjectured that the Boolean function f : { 0 , 1 } n → { 0 , 1 } that maximizes the ...

A directed isoperimetric inequality with application to Bregman near neighbor lower bounds
, 2015 Bregman divergences $D_\phi$ are a class of divergences parametrized by a convex function $\phi$ and include well known distance functions like $\ell_2^2$ and the Kullback-Leibler divergence.

Preconditioner Design via the Bregman Divergence
, 2023 We study a preconditioner for a Hermitian positive definite linear system, which is obtained as the solution of a matrix nearness problem based on the Bregman log determinant divergence. The preconditioner is of the form of a Hermitian positive definite matrix plus a low-rank matrix.

British Journal of Clinical Psychology, EarlyView.Abstract Objectives A cohesive sense of self depends on intact autobiographical memory, both of which are impaired in dissociative disorders. Maladaptive daydreaming (MD), a recently proposed dissociative condition, involves excessive immersion in fantastical inner worlds, often at the expense of real‐life engagement, leading to distress and functional

Geographic risks to functional groups of mammals and birds from habitat loss in Mexico
Conservation Biology, EarlyView.Abstract There is a need to quantify the impact of habitat loss due to anthropogenic factors on different aspects of biodiversity, such as functional trait diversity represented by functional groups (FGs). We developed a metric to assess the weighted risk of loss of habitat for 33 FGs of mammals and 36 FGs of birds in Mexico based on potential ...

Binary Classification with a Pseudo Exponential Model and Its Application for Multi-Task Learning
Entropy, 2015 In this paper, we investigate the basic properties of binary classification with a pseudo model based on the Itakura–Saito distance and reveal that the Itakura–Saito distance is a unique appropriate measure for estimation with the pseudo model in the ...

Generalised Mixability, Constant Regret, and Bayesian Updating [PDF]
, 2014 Mixability of a loss is known to characterise when constant regret bounds are achievable in games of prediction with expert advice through the use of Vovk's aggregating algorithm.

A Contextual Accuracy Dominance Argument for Probabilism
Philosophy and Phenomenological Research, EarlyView.ABSTRACT A central motivation for Probabilism—the principle of rationality that requires one to have credences that satisfy the axioms of probability—is the accuracy dominance argument: one should not have accuracy dominated credences, and one avoids accuracy dominance just in case one satisfies Probabilism.
