Understanding the Brain's Predictive Processing and Cognitive Architecture
Exploring the fascinating realm of brain function and cognition, this content delves into topics like deep learning systems, big data implications, the predictive nature of the brain, cortical hierarchy, active inference, generative models, and cognitive architectures explaining various mental conditions such as schizophrenia, autism, depression, and more. It emphasizes the brain's role as a prediction engine and its constant attempt to anticipate and interpret internal and external stimuli, shedding light on the complex mechanisms underlying human cognition.
