Neuroscience · Theoretical Neuroscience · Active Inference · b. 1959 · British
One of the world's most-cited neuroscientists - architect of the free-energy principle and active inference, a unifying theory of brain and mind.
Biography
Karl Friston created Statistical Parametric Mapping (SPM), the standard software for fMRI analysis, then proposed the free-energy principle: that all self-organizing systems, including brains, act to minimize variational free energy. His active inference framework is increasingly applied to AI agent design.
