A Linear Temporal Logic of Frequencies on Series of Events
Melissa Antonelli, Leonardo Ceragioli, Alessandro Giuseppe Buda +1
This paper introduces LTLF, a temporal logic designed to express the frequency properties of event series in a natural but rigorous manner. By introducing novel, measure-sensitive…
Counting Worlds Branching Time Semantics for post-hoc Bias Mitigation in generative AI
Alessandro G. Buda, Giuseppe Primiero, Leonardo Ceragioli +1
Generative AI systems are known to amplify biases present in their training data. While several inference-time mitigation strategies have been proposed, they remain largely empiric…
A Proof System with Causal Labels (Part II): checking Counterfactual Fairness
Leonardo Ceragioli, Giuseppe Primiero
In this article we propose an extension to the typed natural deduction calculus TNDPQ to model verification of counterfactual fairness in probabilistic classifiers. This is obtaine…
A Proof System with Causal Labels (Part I): checking Individual Fairness and Intersectionality
Leonardo Ceragioli, Giuseppe Primiero
In this article we propose an extension to the typed natural deduction calculus TNDPQ to model verification of individual fairness and intersectionality in probabilistic classifier…
Trustworthiness Preservation by Copies of Machine Learning Systems
Leonardo Ceragioli, Giuseppe Primiero
A common practice of ML systems development concerns the training of the same model under different data sets, and the use of the same (training and test) sets for different learni…
