Effective non-parametric density estimation is a key challenge in high-dimensional multivariate data analysis. In this paper,we propose a novel approach that builds upon tensor factorization tools. Any multivariate density can
Learning Compact Physics-Aware Delayed Photocurrent Models Using Dynamic Mode Decomposition. (arXiv:2008.12319v1 [physics.comp-ph])
Radiation-induced photocurrent in semiconductor devices can be simulated using complex physics-based models, which are accurate, but computationally expensive. This presents a challenge for implementing device characteristics in high-level circuit simulations
The Impact of Discretization Method on the Detection of Six Types of Anomalies in Datasets. (arXiv:2008.12330v1 [cs.DB])
Anomaly detection is the process of identifying cases, or groups of cases, that are in some way unusual and do not fit the general patterns present in the dataset. Numerous
Certainty Equivalent Perception-Based Control. (arXiv:2008.12332v1 [cs.LG])
In order to certify performance and safety, feedback control requires precise characterization of sensor errors. In this paper, we provide guarantees on such feedback systems when sensors are characterized by
Theoretical formulations on thermodynamics of quantum impurity systems. (arXiv:2008.12301v1 [quant-ph])
In this work, we put forward the theoretical foundation toward thermodynamics of quantum impurity systems measurable in experiments. The theoretical developments involve the identifications on two types of thermodynamic entanglement
Destabilization of the U(1) Dirac spin liquid phase on the triangular lattice by quenched disorder. (arXiv:2008.12307v1 [cond-mat.str-el])
It has been recently demonstrated [Song et al., Nature Comm. 10, 4254 (2019), Iqbal et al., Phys. Rev. B 93, 144411 (2016)] that the staggered $\pi$-flux Dirac spin liquid phase
Short- and medium-range orders in Al90Tb10 glass and their relation to the structures of competing crystalline phases. (arXiv:2008.12316v1 [cond-mat.mtrl-sci])
Molecular dynamics simulations using an interatomic potential developed by artificial neural network deep machine learning are performed to study the local structural order in Al90Tb10 metallic glass. We show that
Analytic solutions of scalar perturbations induced by scalar perturbations. (arXiv:2008.12300v1 [gr-qc])
We study scalar perturbations induced by scalar perturbations through the non-linear interaction appearing at second order in perturbations. We derive analytic solutions of the induced scalar perturbations in a perfect
The Importance of Priors on LIGO-Virgo Parameter Estimation: the Case of Primordial Black Holes. (arXiv:2008.12320v1 [astro-ph.CO])
The black holes detected by current and future interferometers can have diverse origins. Their expected mass and spin distributions depend on the specifics of the formation mechanisms. When a physically
Black Hole versus Naked Singularity via Axial Perturbation. (arXiv:2008.12327v1 [gr-qc])
We differentiate non-extremal black hole, \emph{extremal} black hole and \emph{naked singularity} via metric perturbations for Reissner-Nordstr\”{o}m spacetime. First we study the axial perturbations for \emph{extremal} Reissner-Nordstr\”{o}m black hole and compute
