“…This work paves the way for using and developing new alternative methods to improve the learning (e.g new estimator of mu-tual information (Colombo et al, 2021a), Wasserstein Barycenters (Colombo et al, 2021b), Data Depths (Staerman et al, 2021), Extreme Value Theory (Jalalzai et al, 2020)). A future line of research involves using this methods for emotion (Colombo et al, 2019;Witon et al, 2018) and dialog act (Chapuis et al, 2021(Chapuis et al, , 2020a classification with pretrained model tailored for spoken language (Dinkar et al, 2020).…”
