Rethinking Domain Generalization for Face Anti-spoofing: Separability and Alignment [PDF]
Computer Vision and Pattern Recognition, 2023 This work studies the generalization issue of face anti-spoofing (FAS) models on domain gaps, such as image resolution, blurriness and sensor variations.

Separability Transitions in Topological States Induced by Local Decoherence. [PDF]
Physical Review Letters, 2023 We study states with intrinsic topological order subjected to local decoherence from the perspective of separability, i.e., whether a decohered mixed state can be expressed as an ensemble of short-range entangled pure states.

Symmetry-Enforced Many-Body Separability Transitions [PDF]
PRX Quantum, 2023 We study quantum many-body mixed states with a symmetry from the perspective of , i.e., whether a mixed state can be expressed as an ensemble of short-range-entangled symmetric pure states.

Transferability Estimation using Bhattacharyya Class Separability [PDF]
Computer Vision and Pattern Recognition, 2021 Transfer learning has become a popular method for leveraging pre-trained models in computer vision. However, without performing computationally expensive fine-tuning, it is difficult to quantify which pre-trained source models are suitable for a specific

A novel intrinsic measure of data separability [PDF]
Applied intelligence (Boston), 2021 In machine learning, the performance of a classifier depends on both the classifier model and the separability/complexity of datasets. To quantitatively measure the separability of datasets, in this study, we propose an intrinsic measure – the Distance ...

Concomitant extraction of natural stone blocks in a crushed stone quarry
Технічна інженерія, 2022 Most crushed granite quarries in Ukraine have areas with low fracturing, which allows mining blocks of natural decorative stone, and in some quarries these areas are significant in volume, for example, as in the Leznikovskyi quarry.

Separability Criterion for Density Matrices. [PDF]
Physical Review Letters, 1996 A quantum system consisting of two subsystems is {ital separable} if its density matrix can be written as {rho}={summation}{sub {ital Aw}}{sub {ital A}}{rho}{prime}{sub {ital A}}{circle_times}{rho}{double_prime}{sub {ital A}}, where {rho}{prime}{sub ...

A note on entanglement classification for tripartite mixed states
Acta Polytechnica, 2022 We study the classification of entanglement in tripartite systems by using Bell-type inequalities and principal basis. By using Bell unctions and the generalized three dimensional Pauli operators, we present a set of Bell inequalities which classifies ...

Killing Tensor and Carter Constant for Painlevé–Gullstrand Form of Lense–Thirring Spacetime
Universe, 2021 Recently, the authors have formulated and explored a novel Painlevé–Gullstrand variant of the Lense–Thirring spacetime, which has some particularly elegant features, including unit-lapse, intrinsically flat spatial 3-slices, and some particularly simple ...

An Operational Characterization of Soft Topologies by Crisp Topologies
Mathematics, 2021 This paper contributes to the expanding literature on soft topology. We first prove that soft topologies can be characterized by crisp topologies. This takes advantage of two connected constructions that produce soft topologies from crisp topologies and ...
