A Leave-One-Out Influence Statistic for Density-Based Outlier Detection
Aurélien Nicosia, Thierry Duchesne, Michel Carbon
We propose a density-based leave-one-out influence score for unsupervised outlier detection. The motivation is that outliers are naturally associated with regions of very small pro…

A generalized angular regression model with a circular random intercept and a scalar random slope
Aurélien Nicosia
Clustered circular responses arise in repeated orientation experiments, movement ecology, and sensor studies, where both directionality and within-cluster dependence matter. We pro…

Tropical Viterbi Tubes for Decoding Uncertainty in Hidden Markov Models
Aurélien Nicosia
Hidden Markov models are widely used to infer latent state sequences from sequential data, but Viterbi decoding reports only one most likely complete path. When decoded states carr…
