Hyperspectral Denoising Using Asymmetric Noise Modeling Deep Image Prior

open access: yesRemote Sensing, 2023
Deep image prior (DIP) is a powerful technique for image restoration that leverages an untrained network as a handcrafted prior. DIP can also be used for hyperspectral image (HSI) denoising tasks and has achieved impressive performance.

Some Generalizations of Weibull Distribution and Related Processes [PDF]

open access: yesJournal of Statistical Theory and Applications (JSTA), 2015
A new class of distributions containing Marshall-Olkin extended Weibull distribution is introduced. The role of this distribution in the study of minification process is established.

RECORD RANGES FOR SAMPLES FROM ASYMMETRICAL LAPLACE DISTRIBUTIONS [PDF]

open access: yesJournal of Statistical Theory and Applications, 2018
The representations of record ranges via sums of independent identically distributed exponential random variables are obtained for asymmetrical Laplace distributions. This result generalizes the corresponding relations for record values in the cases of exponential and negative exponential ...

Poissonian resetting of subdiffusion in a linear potential

open access: yesCondensed Matter Physics, 2023
Resetting a stochastic process is an important problem describing the evolution of physical, biological and other systems which are continually returned to their certain fixed point. We consider the motion of a subdiffusive particle with a constant drift

Mixtures of Shifted Asymmetric Laplace Distributions [PDF]

open access: yesIEEE Transactions on Pattern Analysis and Machine Intelligence, 2014
In this thesis we introduce a mixture of shifted asymmetric Laplace (SAL) distributions for model-based clustering and classification. The mixture of SAL distributions allows for the parameterization of skewness as well as location and scale. Furthermore, we extend the general SAL mixture by decomposing the component scale matrices; this results in two

Bayesian composite quantile regression for the single-index model.

open access: yesPLoS ONE, 2023
By using a Gaussian process prior and a location-scale mixture representation of the asymmetric Laplace distribution, we develop a Bayesian analysis for the composite quantile single-index regression model.

A Value-at-Risk forecastability indicator in the framework of a Generalized Autoregressive Score with “Asymmetric Laplace Distribution”

open access: yes, 2021
In the present paper we discuss the forecasting ability of the VaR model, within the context of a Generalized Autoregressive Score (GAS). The proposed method considers an Asymmetric Laplace Distribution (GAS-ALD) to describe the daily log-returns of the ...

Inference for grouped data with a truncated skew-Laplace distribution [PDF]

open access: yes, 2010
The skew-Laplace distribution has been used for modelling particle size with point observations. In reality, the observations are truncated and grouped (rounded).

A note on the multivariate generalized asymmetric Laplace motion [PDF]

open access: yes, 2020
In this note we use multivariate subordination to introduce a multivariate extension of the generalized asymmetric Laplace motion. The class introduced provides a unified framework for several multivariate extensions of the popular variance gamma ...
