Overview
On June 21st, 2021, Active Inference Lab ( activeinference.org/ ) hosted its first Applied Active Inference Symposium, featuring Professor Karl Friston. The Symposium was structured in three sections, corresponding to the Organizational Units of the Active Inference Lab: Education, Communication, and Tools. This publication reflects an edited and enriched transcript of the proceedings of the Symposium.

Findings and contributions
- Friston recommends toy simulations as the best way to demystify Active Inference for learners in an academic setting.
- Friston stresses that getting the generative model right is central: if it is apt for the target system, everything else usually follows.
- Friston distinguishes Active Inference from predictive coding: minimizing variational free energy is only half the game, with expected free energy needed for future-oriented action.
- On tools, Friston argues anything can be written as a generative model and hence as a variational free-energy-minimizing message-passing scheme, citing ForneyLab.
- Friston describes epidemic modeling with PCR incidence and mobility data, using Bayesian optimal design to judge whether including a data source is worth the complexity.
Methods
- Edited transcript of a three-session moderated symposium — Records the first Applied Active Inference Symposium with Karl Friston, organized into .edu, .comms and .tools sessions mirroring the lab's organizational units.
- Prepared question slides posed by lab participants to Friston — Lab members developed questions in weekly meetings and presented them as slides; Friston answered and moderators gave recaps.
- Presentation of the lab's Active Inference terms list and ontology work — The .edu session presented the lab's terms list and working ontology, developed within the SUMO ontology framework as a backbone for education.
