Kaplan-Meier type survival curves for COVID-19: a health data based decision-making tool
J. M. Calabuig, L. M. García-Raffi, A. García-Valiente +1
Countries are recording health information on the global spread of COVID-19 using different methods, sometimes changing the rules after a few days. They are all publishing the numb…
Dreaming machine learning: Lipschitz extensions for reinforcement learning on financial markets
J. M. Calabuig, H. Falciani, E. A. Sánchez-Pérez
We consider a quasi-metric topological structure for the construction of a new reinforcement learning model in the framework of financial markets. It is based on a Lipschitz type e…
Graph distances for determining entities relationships: a topological approach to fraud detection
J. M. Calabuig, H. Falciani, A. Ferrer-Sapena +2
Given a set and a proximity function , we define a new metric for by considering a path distance in , that is considered as a complete graph…
Equivalent Norms in a Banach Function Space and the Subsequence Property
Jose M. Calabuig, Maite Fernández Unzueta, Fernando Galaz-Fontes +1
Given a finite measure space , we show that any Banach space consisting of (equivalence classes of) real measurable functions defined on such that $f χ_A \in X(…
