Monte Carlo comparison of estimation methods for the two-parameter lognormal distribution

open access: yesMATEC Web of Conferences, 2019
In the paper we compare performance of estimation methods for the two-parameter lognormal distribution via the Monte Carlo simulation. The comparison of performances is made with respect to their biases, variances, root mean square error. The methods are

A moment-distance hybrid method for estimating a mixture of two symmetric densities

open access: yesModern Stochastics: Theory and Applications, 2018
In clustering of high-dimensional data a variable selection is commonly applied to obtain an accurate grouping of the samples. For two-class problems this selection may be carried out by fitting a mixture distribution to each variable.

The zero inflated negative binomial – Crack distribution: some properties and parameter estimation [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2015
The zero inflated negative binomial-Crack (ZINB-CR) distribution is a mixture of Bernoulli distribution and negative binomial-Crack (NB-CR) distribution, which is an alternative distribution for the excessive zero counts and overdispersion.

Surface Profile Recovery from Electromagnetic Fields with Physics-Informed Neural Networks

open access: yesRemote Sensing
Physics-informed neural networks (PINN) have shown their potential in solving both direct and inverse problems of partial differential equations. In this paper, we introduce a PINN-based deep learning approach to reconstruct one-dimensional rough ...
