“…In such situations, action model learning approaches that assume correct traces, such as (Yang, Wu, and Jang 2007;Cresswell and Gregory 2011;Cresswell, McCluskey, and West 2013;Stern and Juba 2017;Lamanna et al 2021), are not applicable. There are existing approaches designed for handling noisy traces (Rodrigues, Gérard, and Rouveirol 2011;Mourão et al 2012;Segura-Muros, Pérez, and Fernández-Olivares 2018;Grand, Pellier, and Fiorino 2020); however, we believe that the problem of action model learning from noisy plan traces cannot be considered fully addressed; especially when the noise level is particularly high, where current state-of-the-art approaches do not provide a satisfactory performance.…”
