Goodness of fit by Neyman-Pearson testing

1 code implementation23 May 2023 Gaia Grosso, Marco Letizia, Maurizio Pierini, Andrea Wulzer

The Neyman-Pearson strategy for hypothesis testing can be employed for goodness of fit if the alternative hypothesis is selected from data by exploring a rich parametrised family of models, while controlling the impact of statistical fluctuations.

Comparative Study of Coupling and Autoregressive Flows through Robust Statistical Tests

1 code implementation23 Feb 2023 Andrea Coccaro, Marco Letizia, Humberto Reyes-Gonzalez, Riccardo Torre

Normalizing Flows have emerged as a powerful brand of generative models, as they not only allow for efficient sampling of complicated target distributions, but also deliver density estimation by construction.

Efficient Unsupervised Learning for Plankton Images

no code implementations14 Sep 2022 Paolo Didier Alfano, Marco Rando, Marco Letizia, Francesca Odone, Lorenzo Rosasco, Vito Paolo Pastore

We compare our method with state-of-the-art unsupervised approaches, where a set of pre-defined hand-crafted features is used for clustering of plankton images.
