Conjecture

Exploration in active inference is a designed quantity, not a consequence of the principle. The expected free energy of a course of action can be rearranged into an expected-value term and an expected-information-gain term, so an agent minimising it is drawn to sample where it would learn most and weighs exploration against exploitation in one quantity; this answers the dark-room worry that action can only make sensations more predictable. Three limits keep that from being a law. The split is derived from the assumption that a thing's fluctuations are small, so built-in curiosity is a result for precise particles, not for everything with a Markov blanket. Unlike variational free energy, expected free energy is not a bound on surprise, so minimising it guarantees nothing about surprise. And the objective can be factored in several ways, with working agents weighting its terms differently (for instance down-weighting exploration to converge faster), so how much an agent explores is fixed by the designer's factoring and weights.

  • groundsSource document

    we can express expected free energy in terms of *expected value* and *expected information gain*

  • groundsSource document

    Expected free energy has a specific form that inherits from the assumption that the amplitude of particular fluctuations is small

  • groundsSource document

    variational free energy is a bound on surprisal, while expected free energy is not a bound

  • groundsSource document

    While this aspect of active inference has been the target of critics

  • groundsSource document

    weighting could lead to different behaviors that might come in use for practical purposes

Expected free energy splits into expected value and expected information gain, so active inference does not bolt exploration on: it is half of the objective.

Why. Merge S-MXX3C9G61W: the decomposition, its precise-particle derivation and its non-unique weighting are one claim about the status of exploration.

Expected free energy, and with it built-in curiosity, is derived only for precise particles, and unlike variational free energy it is not a bound on surprise.

Why. Merge S-MXX3C9G61W: the decomposition, its precise-particle derivation and its non-unique weighting are one claim about the status of exploration.

Expected free energy is a family of tunable objectives; the designer's weights, not the principle, fix the behaviour.

Why. Merge S-MXX3C9G61W: the decomposition, its precise-particle derivation and its non-unique weighting are one claim about the status of exploration.
