I quite often draw this parallel, so this paper may be useful to me. It's nice he sees the parallels. But to me he is just fitting a formalism to an underlying observation that cognition and our perception of physics have parallels. Cognition behaves in many ways like quantum mechanics. It's been observed before. Though it is true that this is not yet embraced or understood, and I would identify that as the key problem holding AI back. This is just another formalism to express that. There are others. To me the underlying insight is just the surprising complexity you get from emergent structure. However, if Friston brings more focus to this, it may be the path for the field to understand and embrace it. Which will be good. Though I think the essential insights can get buried in his formalism. Crucially I think non-linearity of combinations gets lost (in his generative models.) For instance I'm not sure if the linear simplification of Markov blankets is justified. Assuming relationships are linear so the maths can be tractable strikes me as a key failing in most Active Inference work. -Rob ------------------------------------------ Artificial General Intelligence List: AGI Permalink: https://agi.topicbox.com/groups/agi/T903bb1e5785b431f-M0e39373793808d2012b0328e Delivery options: https://agi.topicbox.com/groups/agi/subscription
