The authors assess how decoder confusion patterns affect sequential goal identification. Their method treats a confusion matrix as a communication channel, measures pairwise distinguishability, and computes Uid, a cumulative identification envelope. Under stated assumptions, distinct rows yield bounded identification error, while identical rows imply linear regret growth. In EEG reaching replay, equally accurate decoders had 9.6× different held-out regret; deployment remains untested.
