The Evolution of Intelligence and Learning Patterns
The podcast episode delves into the journey of intelligence evolution, revealing how creatures navigate their environments and develop learning patterns over time. It discusses the emergence of structures like the neocortex in mammals, highlighting the role of self-supervision and generative modeling in neural networks. The conversation explores how simpler creatures relied on reflexes, while mammals developed simulation abilities for adaptive behaviors.
Active Inference and Self-Modeling
The discussion transitions to active inference principles, emphasizing the neocortex's function in modeling an individual's behavior and intentions. Carl Fristen's concept of active inference AI is referenced, challenging the idea of behavior solely driven by rewards. The interaction between self-modeling and reward-based actions in mammalian brains is explored as a foundational aspect of cognition.
Language as a Cognitive Tool
Language's role as a cognitive tool for sharing mental simulations is elaborated upon, emphasizing its significance in collaborative planning and communication. The podcast episode emphasizes that while language enhances human thinking and enables idea refinement, its initial evolutionary purpose was rooted in facilitating coordinated actions and sharing plans.
Continual Learning Challenges in AI
The conversation navigates into the realm of continual learning challenges in artificial neural networks, addressing the need for systems to adapt and grow with new information. The debate between augmenting existing models with memory stores versus reimagining learning algorithms for true continual learning capabilities is explored as a prominent avenue of AI research.
Intersection of Biological and Artificial Intelligence
The podcast episode concludes by examining how biological intelligence intersects with advancements in artificial intelligence, particularly in the context of developing models that emulate human learning capacities. It touches on the quest to bridge the gap between established learning patterns in mammals and the ongoing efforts to embed similar mechanisms within AI systems for enhanced adaptability and intelligence.
Max Bennett is the author of 'A Brief History of Intelligence: Evolution, AI, and Five Breakthroughs That Made Our Brains.' In this episode Andrea Hiott and Max discuss his journey from working in AI technology commercialization to embarking on a five-year passion project that led to writing the book. He explains the motivation behind studying the discrepancies between human brain functionality and AI systems, resulting in several published papers and collaborations with neuroscientists. The discussion delves into intelligence before brains, as Max argues against the notion that intelligence is exclusive to brains, highlighting the evolutionary history and complexity of intelligence across different life forms. They cover various breakthroughs in understanding intelligence, including steering, reinforcement learning, and the emergence of language as a tool for sharing mental simulations. Their conversation touches upon the implications of language for human intelligence, its role in facilitating complex planning and cooperation, and the feedback loop it creates for refining thought processes. It also gets into the potential of AI in continuous learning and the challenges in achieving a system that learns in real time (like the human brain!)
