Utile Distinction Hidden Markov Models
... As noted before, including the utility in the observation is only done during model learning. During trial execution (model solving), returns are not available yet, since they depend on future events. Therefore, online belief updates are done ignoring the utility information. It should be noted that ...

The results from the corrected data produce more reasonable results (see Appendix C). With the outlier deleted ...
