Statistical Agnostic Regression: a machine learning method to validate regression models

no code implementations23 Feb 2024 Juan M Gorriz, J. Ramirez, F. Segovia, F. J. Martinez-Murcia, C. Jiménez-Mesa, J. Suckling

Regression analysis is a central topic in statistical modeling, aiming to estimate the relationships between a dependent variable, commonly referred to as the response variable, and one or more independent variables, i. e., explanatory variables.

Is K-fold cross validation the best model selection method for Machine Learning?

no code implementations29 Jan 2024 Juan M Gorriz, F Segovia, J Ramirez, A Ortiz, J. Suckling

A novel statistical test based on K-fold CV and the Upper Bound of the actual error (K-fold CUBV) is composed, where uncertain predictions of machine learning with CV are bounded by the \emph{worst case} through the evaluation of concentration inequalities.

Tiled sparse coding in eigenspaces for the COVID-19 diagnosis in chest X-ray images

no code implementations28 Jun 2021 Juan E. Arco, Andrés Ortiz, Javier Ramírez, Juan M Gorriz

In this work, we propose a classification framework based on sparse coding in order to identify the pneumonia patterns associated with different pathologies.
