298. Perception: Chaos and Order | Dr. Karl Friston

Dr. Peterson's extensive catalog is available now on DailyWire+: https://utm.io/ueSXh Dr. Jordan B. Peterson and Dr. Karl Friston discuss the world as we perceive it through micro narratives, how those narratives exist within a structured hierarchy, and how we can manipulate the system, and thus change our own mindsets. Dr. Karl Friston is a renowned neuroscientist, and one of the leading researchers in brain imagery. He is credited for inventing statistical parametric mapping, an international standard for the analysis of imaging data. His work also pertains to the free energy principle, and predictive coding theory. Currently, he works as a professor of neuroscience at the University College London. — Sponsors  — Hallow: Try Hallow for 3 months FREE: https://hallow.com/jordan Invest in art today with Masterworks at http://masterworks.art/jbp.See important disclosures at https://masterworks.com/cd. — Chapters — (0:00) Coming up(1:04) Intro(2:43) The binding of entropy(5:25) Motivation and Fantasy(15:00) Hierarchy of micro narratives(29:30) Frans de Waal, the paradox in prediction(37:50) Inference and assuming the story(46:15) Dopamine and diatic narratives(54:33) Serotonin, the depressive mindset(1:07:31) Acetylcholine(1:10:29) The need to minimize free energy(1:16:48) The left and right hemisphere(1:22:20) Psychedelics and functional narratives  // SUPPORT THIS CHANNEL //Newsletter: https://mailchi.mp/jordanbpeterson.com/youtubesignupDonations: https://jordanbpeterson.com/donate // COURSES //Discovering Personality: https://jordanbpeterson.com/personalitySelf Authoring Suite: https://selfauthoring.comUnderstand Myself (personality test): https://understandmyself.com // BOOKS //Beyond Order: 12 More Rules for Life: https://jordanbpeterson.com/Beyond-Order12 Rules for Life: An Antidote to Chaos: https://jordanbpeterson.com/12-rules-for-lifeMaps of Meaning: The Architecture of Belief: https://jordanbpeterson.com/maps-of-meaning // LINKS //Website: https://jordanbpeterson.comEvents: https://jordanbpeterson.com/eventsBlog: https://jordanbpeterson.com/blogPodcast: https://jordanbpeterson.com/podcast // SOCIAL //Twitter: https://twitter.com/jordanbpetersonInstagram: https://instagram.com/jordan.b.petersonFacebook: https://facebook.com/drjordanpetersonTelegram: https://t.me/DrJordanPetersonAll socials: https://linktr.ee/drjordanbpeterson #JordanPeterson #JordanBPeterson #DrJordanPeterson #DrJordanBPeterson #DailyWirePlus

How Free Energy Constructs Our Reality | Michael Levin and Karl Friston

Curt Jaimungal is joined by Michael Levin, a regenerative biology expert known for creating anthrobots, and Karl Friston, a leading neuroscientist who formulated the free energy principle. They delve into how self-organization shapes our reality through entropy and noise. The conversation highlights the adaptability of biological systems and the role of creativity in evolution, examining the intersections of noise and identity. They also discuss psychological patterns and how our understanding of selfhood affects perceptions of existence and consciousness.

Karl Friston ~ Active Inference Insights 001 ~ Free Energy, Time, Consciousness

In this episode, Darius Parvizi-Wayne interviews Karl Friston, the chief architect of active inference. They discuss the free energy principle, boundary states, and the mark of blanket. They explore the difference between a 'whats governor' and a human, minimizing expected surprise, and the role of priors. The conversation also covers beliefs and temporal depth in generative models, the free energy principle and the statistical manifold, and dynamics and flows in a random dynamical system. They touch on strange loops, the holographic principle, free will, and consciousness. The podcast ends with discussions on self-destructive behavior, imperatives and optimization in the free energy principle, and the philosophical debate on whether life is inherently good.

#033 Prof. Karl Friston - The Free Energy Principle

This week Dr. Tim Scarfe, Dr. Keith Duggar and Connor Leahy chat with Prof. Karl Friston. Professor Friston is a British neuroscientist at University College London and an authority on brain imaging. In 2016 he was ranked the most influential neuroscientist on Semantic Scholar.  His main contribution to theoretical neurobiology is the variational Free energy principle, also known as active inference in the Bayesian brain. The FEP is a formal statement that the existential imperative for any system which survives in the changing world can be cast as an inference problem. Bayesian Brain Hypothesis states that the brain is confronted with ambiguous sensory evidence, which it interprets by making inferences about the hidden states which caused the sensory data. So is the brain an inference engine? The key concept separating Friston's idea from traditional stochastic reinforcement learning methods and even Bayesian reinforcement learning is moving away from goal-directed optimisation.
