Analytic

Three kinds of surprise come apart; a redundant cue has zero Bayesian surprise but positive surprisal.

The claim

Three quantities called surprise come apart: the Rescorla-Wagner prediction error, Bayesian surprise (the complexity term, the shift from prior to posterior) and surprisal (negative log evidence). In the Anokhin et al. blocking model a redundant cue produces zero Bayesian surprise yet positive surprisal. "Prediction error" therefore names more than one thing, and a claim about it must say which.

    so a Bayesian surprise(complexity) will be zero

    However the agent will still be "surprised"

    T=4 L=95 above=Active inference scales in silico only by borrowing deep-learning machinery it did not originate. below=Reward prediction error is a by-product in active inference, not the driver, unless the rule is changed to make it one. | Follows from the decomposition and is shown in their simulation.
