Score Broadcast and Decorrelation: A General Framework for Broadcast-Based Credit Assignment
Researchers introduce Score Broadcast and Decorrelation (SBD), a theoretical framework that generalizes biologically plausible credit assignment mechanisms across diverse loss functions beyond MSE. The framework unifies error broadcast—an alternative to backpropagation that avoids weight transport—under a single orthogonality principle, with experimental validation showing improvements over existing broadcast approaches on image classification tasks.
