Uncertainty-Aware Fairness-Adaptive Classification Trees
Anna Gottard, Vanessa Verrina, Sabrina Giordano
In an era where artificial intelligence and machine learning algorithms increasingly impact human life, it is crucial to develop models that account for potential discrimination in…
Hidden Markov Models for Longitudinal Rating Data with Dynamic Response Styles
R. Colombi, S. Giordano, M. Kateri
This work deals with the analysis of longitudinal ordinal responses. The novelty of the proposed approach is in modeling simultaneously the temporal dynamics of a latent trait of i…
Modelling Ordinal Responses with Uncertainty: a Hierarchical Marginal Model with Latent Uncertainty components
Roberto Colombi, Sabrina Giordano, Anna Gottard +1
In responding to rating questions, an individual may give answers either according to his/her knowledge/awareness or to his/her level of indecision/uncertainty, typically driven by…
Multiple Hidden Markov Models for Categorical Time Series
Roberto Colombi, Sabrina Giordano
We introduce multiple hidden Markov models (MHMMs) where an observed multivariate categorical time series depends on an unobservable multivariate Mar- kov chain. MHMMs provide an e…
