Predictive processing techniques

Definition

Predictive processing techniques refer to a framework in neuroscience and cognitive science that posits that the brain constantly generates predictions about sensory inputs and updates these predictions based on incoming information. This model emphasizes the importance of real-time processing and low-latency response in enabling efficient interactions with the environment by minimizing prediction errors and enhancing decision-making capabilities.
