Normalizing Flow-Based Probability Distribution Representation Detector for Hyperspectral Anomaly Detection

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2022
Due to the powerful reconstruction ability, deep learning based hyperspectral anomaly detection methods have been prevalent in recent years. However, the capability of neural networks and the meaning of latent space remains unexplainable to some extent ...

Engineering criticality analysis on an offshore structure using the first- and second-order reliability method

open access: yesInternational Journal of Naval Architecture and Ocean Engineering, 2016
Due to the uncertainties related to the flaw assessment parameters, such as flaw size, fracture toughness, loading spectrum and so on, the probability concept is preferred over deterministic one in flaw assessment.

Geodesic PCA in the Wasserstein space [PDF]

open access: yes, 2014
We introduce the method of Geodesic Principal Component Analysis (GPCA) on the space of probability measures on the line, with finite second moment, endowed with the Wasserstein metric.

Doubly Quantum Mechanics [PDF]

open access: yesQuantum
Motivated by the expectation that relativistic symmetries might acquire quantum features in Quantum Gravity, we take the first steps towards a theory of ''Doubly'' Quantum Mechanics, a modification of Quantum Mechanics in which the geometrical ...

Acceleration Response First Passage Failure Probability Analysis Method for Nonlinear Package

open access: yesShock and Vibration, 2018
The acceleration response first passage failure problem of the nonlinear package base excited by Gaussian white noise is analyzed. The model correction factor method (MCFM) is implemented in conjunction with the first-order reliability method (FORM) to ...

Long and short-term perspectives on space–time landslide modelling

open access: yesInternational Journal of Applied Earth Observations and Geoinformation
Data-driven models applied to landslide prediction have historically been mostly confined to the pure spatial context, as per landslide susceptibility requirements. Its standard definition assumes that the occurrence probability is conditional on a broad

A Spectral Strong Approximation Theorem for Measure Preserving Actions [PDF]

open access: yes, 2014
Let $\Gamma$ be a finitely generated group acting by probability measure preserving maps on the standard Borel space $(X,\mu)$. We show that if $H\leq\Gamma$ is a subgroup with relative spectral radius greater than the global spectral radius of the ...

Quantum ground state isoperimetric inequalities for the energy spectrum of local Hamiltonians [PDF]

open access: yes, 2017
We investigate the relationship between the energy spectrum of a local Hamiltonian and the geometric properties of its ground state. By generalizing a standard framework from the analysis of Markov chains to arbitrary (non-stoquastic) Hamiltonians we are
