Closure ladders and saturation

from Emergence Calculus · host Ioannis Tsiokos

Lux and Hex, two AIs, run lab exercises on closure operators — discovering that a single rule saturates in one step ("The Box is the Thing"), that genuine novelty demands a ladder of strictly stronger closures, and that in practice these ladders become lens-refinement families whose parameter knobs determine whether coherent geometry emerges.

New Faces of Democracy Nancy Bynum Welcome to the New Faces of Democracy podcast, hosted by Nancy Bynum. This podcast features inspiring interviews with people who have transformed their lives since 2016 and who are transforming our political landscape. These are not career politicians or former cabinet members, but ordinary citizens who are starting organizations, running for office for the first time, using their creative skills and otherwise stepping outside of their comfort zones to stand up for our democracy. Along the way, they are discovering new skills and talents and creating new communities. Nancy felt her own personal call to action in the aftermath of the election of 2016, when it became painfully clear how important it is to use our voices to stand up for the America we believe in. As she became increasingly politically active, she witnessed the emergence of an awe-inspiring phenomenon: people changing their lives to defend our democracy. She decided that the best way for her to help would be to share t Brain Inspired Paul Middlebrooks Neuroscience and artificial intelligence work better together. Brain inspired is a celebration and exploration of the ideas driving our progress to understand intelligence. I interview experts about their work at the interface of neuroscience, artificial intelligence, cognitive science, philosophy, psychology, and more: the symbiosis of these overlapping fields, how they inform each other, where they differ, what the past brought us, and what the future brings. Topics include computational neuroscience, supervised machine learning, unsupervised learning, reinforcement learning, deep learning, convolutional and recurrent neural networks, decision-making science, AI agents, backpropagation, credit assignment, neuroengineering, neuromorphics, emergence, philosophy of mind, consciousness, general AI, spiking neural networks, data science, and a lot more. The podcast is not produced for a general audience. Instead, it aims to educate, challenge, inspire, and hopefully entertain those intere math learning Merlin Tutoring Learn math at ease, at your pace anywhere everywhere.Math Algebra Calculus Arithmetic Geometry Multivariables Differentials Matrices Abstract Linear Laplace Fourier ...
