On Asymptotics of Optimal Stopping Times
Mathematics, 2022 We consider optimal stopping problems, in which a sequence of independent random variables is drawn from a known continuous density. The objective of such problems is to find a procedure which maximizes the expected reward.

Automatic Evaluation of Neural Network Training Results
Computers, 2023 This article is dedicated to solving the problem of an insufficient degree of automation of artificial neural network training. Despite the availability of a large number of libraries for training neural networks, machine learning engineers often have to

Multi-modal analysis of aerosol robotic network size distributions for remote sensing applications: dominant aerosol type cases [PDF]
Atmospheric Measurement Techniques, 2014 To date, size distributions obtained from the aerosol robotic network (AERONET) have been fit with bi-lognormals defined by six secondary microphysical parameters: the volume concentration, effective radius, and the variance of fine and coarse particle ...

Stop-loss and leverage in optimal statistical arbitrage with an application to energy market [PDF]
Energy Economics, 2019 In this paper we develop a statistical arbitrage trading strategy with two key elements in hi-frequency trading: stop-loss and leverage. We consider, as in Bertram (2009), a mean-reverting process for the security price with proportional transaction costs; we show how to introduce stop-loss and leverage in an optimal trading strategy.

Anisotropic Diffusion Based Multiplicative Speckle Noise Removal
Sensors, 2019 Multiplicative speckle noise removal is a challenging task in image processing. Motivated by the performance of anisotropic diffusion in additive noise removal and the structure of the standard deviation of a compressed speckle noisy image, we address ...

Density-Based Multiscale Analysis for Clustering in Strong Noise Settings With Varying Densities
IEEE Access, 2018 Finding meaningful clustering patterns in data can be very challenging when the clusters are of arbitrary shapes, different sizes, or densities, and especially when the data set contains high percentage (e.g., 80%) of noise.
