Shedding Light on the Ageing of Extra Virgin Olive Oil: Probing the Impact of Temperature with Fluorescence Spectroscopy and Machine Learning Techniques

no code implementations21 Sep 2023 Francesca Venturini, Silvan Fluri, Manas Mejari, Michael Baumgartner, Dario Piga, Umberto Michelucci

This work systematically investigates the oxidation of extra virgin olive oil (EVOO) under accelerated storage conditions with UV absorption and total fluorescence spectroscopy.

Dataset of Fluorescence Spectra and Chemical Parameters of Olive Oils

no code implementations10 Jan 2023 Francesca Venturini, Michela Sperti, Umberto Michelucci, Arnaud Gucciardi, Vanessa M. Martos, Marco A. Deriu

The dataset includes the values of the following chemical parameters for each olive oil sample: acidity, peroxide value, K270, K232, ethyl esters, and the quality of the samples (EVOO, VOO, or LOO).

On the High Symmetry of Neural Network Functions

no code implementations12 Nov 2022 Umberto Michelucci

This work shows how the neural network function has a number of equivalent minima, in other words minima that give the same value for the loss function and the same exact output, that grows factorially with the number of neurons in each layer for feed forward neural network or with the number of filters in a convolutional neural networks.

New Metric Formulas that Include Measurement Errors in Machine Learning for Natural Sciences

no code implementations30 Sep 2022 Umberto Michelucci, Francesca Venturini

This paper addresses this deficiency by deriving formulas for commonly used metrics (both for regression and classification problems) that take into account measurement errors of target variables.

A Model-Agnostic Algorithm for Bayes Error Determination in Binary Classification

no code implementations24 Jul 2021 Umberto Michelucci, Michela Sperti, Dario Piga, Francesca Venturini, Marco A. Deriu

This paper presents the intrinsic limit determination algorithm (ILD Algorithm), a novel technique to determine the best possible performance, measured in terms of the AUC (area under the ROC curve) and accuracy, that can be obtained from a specific dataset in a binary classification problem with categorical features {\sl regardless} of the model used.

Optical oxygen sensing with artificial intelligence

no code implementations27 Jul 2020 Umberto Michelucci, Michael Baumgartner, Francesca Venturini

In the classical approach, this change is related to an oxygen concentration using the Stern-Volmer equation.
