Channel-Supermodular Entropies: Order Theory and an Application to Query Anonymization [PDF]
Entropy, 2021 This work introduces channel-supermodular entropies, a subset of quasi-concave entropies. Channel-supermodularity is a property shared by some of the most commonly used entropies in the literature, including Arimoto–Rényi conditional entropies (which ...

Quasi-Dense Similarity Learning for Multiple Object Tracking [PDF]
Computer Vision and Pattern Recognition, 2020 Similarity learning has been recognized as a crucial step for object tracking. However, existing multiple object tracking methods only use sparse ground truth matching as the training objective, while ignoring the majority of the informative regions on ...

On the Size of Subclasses of Quasi-Copulas and Their Dedekind–MacNeille Completion
Mathematics, 2020 We study some topological properties of the class of supermodular n-quasi-copulas and check that the topological size of the Dedekind–MacNeille completion of the set of n-copulas is small, in terms of the Baire category, in the Dedekind–MacNeille ...

Reducing the impact of Auger recombination in quasi-2D perovskite light-emitting diodes
Nature Communications, 2021 Rapid Auger recombination represents an important challenge faced by quasi-2D perovskites, which induces resulting perovskite light-emitting diodes’ (PeLEDs) efficiency roll-off.

The no‐upward‐crossing condition, comparative statics, and the moral‐hazard problem
, 2020 We define and explore no-upward-crossing (NUC), a condition satisfied by every parameterized family of distributions commonly used in economic applications.

High-performance large-area quasi-2D perovskite light-emitting diodes
Nature Communications, 2021 Serious performance decline arose for perovskite light-emitting diodes (PeLEDs) once the active area was enlarged. Here we investigate the failure mechanism of the widespread active film fabrication method; and ascribe severe phase-segregation to be the ...

Graph Matching Via the Lens of Supermodularity
IEEE Transactions on Knowledge and Data Engineering, 2022 Graph matching, the problem of aligning a pair of graphs so as to minimize their edge disagreements, has received widespread attention owing to its broad spectrum of applications in data science.

Chiral Quasi-Bound States in the Continuum. [PDF]
Physical Review Letters, 2020 Quasi-bound states in the continuum (QBICs) are Fano resonant states with long optical lifetimes controlled by symmetry-breaking perturbations. While conventional Fano responses are limited to linear polarizations and do not support tailored phase ...

Supermodularity and valid inequalities for quadratic optimization with indicators [PDF]
Mathematical programming, 2020 We study the minimization of a rank-one quadratic with indicators and show that the underlying set function obtained by projecting out the continuous variables is supermodular.
