Hyperspherical Contrastive Representations Unlock Planning and Exploration
Jonghae Park, Sungil Son, Jonghun Shin +3
We develop a self-supervised reinforcement learning algorithm that learns to build towers of up to eight cubes from scratch, without prior data, rewards, demonstrations, or pretrai…
Moments of polynomial processes under affine resetting
Johannes Assefa, Martin Keller-Ressel, Zbigniew Palmowski
We consider polynomial processes, i.e., continuous-time Markov processes that preserve polynomials without increasing degree, and augment them with resetting. Resetting means that…
Early predicting of hospital admission using machine learning algorithms: Priority queues approach
Jakub Antczak, James Montgomery, Małgorzata O'Reilly +2
Emergency Department overcrowding is a critical issue that compromises patient safety and operational efficiency, necessitating accurate demand forecasting for effective resource a…
Hitting the blinking target under stochastic resetting
Bartosz Zbik, Bartłomiej Dybiec, Karol Capała +2
The first hitting times of a stochastic process, i.e., the first time a process reaches a particular level, are of significant interest across various scientific disciplines, inclu…
Finite-Time Ruin for the Compound Markov Binomial Risk Model
Zbigniew Palmowski, Lewis Ramsden, Apostolos D. Papaioannou
In this paper, we study finite-time ruin probabilities for the compound Markov binomial risk model - a discrete-time model where claim sizes are modulated by a finite-state ergodic…
Partial versus total resetting for Lévy flights in d dimensions: similarities and discrepancies
Costantino Di Bello, Aleksei Chechkin, Tomasz Grzywny +3
While stochastic resetting (or total resetting) is less young and more established concept in stochastic processes, partial stochastic resetting (PSR) is a relatively new field. PS…
Stationary states for stable processes with partial resetting
Tomasz Grzywny, Karol Szczypkowski, Zbigniew Palmowski +1
We study a -dimensional stochastic process which arises from a Lévy process by partial resetting, that is the position of the process at a…
Stable random walks in cones
Wojciech Cygan, Denis Denisov, Zbigniew Palmowski +1
In this paper we consider a multidimensional random walk killed on leaving a right circular cone with a distribution of increments belonging to the normal domain of attraction of a…
Branching random walk and log-slowly varying tails
Ayan Bhattacharya, Piotr Dyszewski, Nina Gantert +1
We study a branching random walk with independent and identically distributed, heavy tailed displacements. The offspring law is supercritical and satisfies the Kesten-Stigum condit…
