  • Although Millidge's mathematics uses a POMDP formalism, the code implements a fully observable MDP without an encoder/decoder architecture.

    “Although the mathematics in the paper are based on the formalism of a partially observable Markov decision process (POMDP), the code does not implement an encoder/decoder architecture, that is, the code implements a fully observable decision process, i.e., MDP.”

    From Deconstructing Deep Active Inference: A Contrarian Information Gatherer (2024) · cites this paper as Millidge (2020)

  • The DAI_VPG implementation is a mixture of POMDP and MDP settings, with an MDP generative model and expected free energy adapted from the POMDP setting.

    “Thus, (as it stands) the implementation of the DAI V P G agent is a mixture between the POMDP and MDP setting, where the generative model corresponds to an MDP, and the expected free energy is adapted from the POMDP setting.”

  • The DAI_VPG agent is able to solve the CartPole environment.

    “DAI V P G is able to solve the CartPole environment.”

    From Deconstructing Deep Active Inference: A Contrarian Information Gatherer (2024) · cites this paper as Millidge (2020)

  • The DAI_VPG implementation has no hidden states, which raises uncertainty about how the intrinsic value is computed.

    “Now, remember that in the implementation, there is no encoder Q(s τ ) and no decoder P (o τ |s τ ).In other words, there are no hidden states s τ , raising some uncertainty about how the intrinsic value is computed.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
