Predictive coding shows higher sample efficiency than backpropagation

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new metric called "target alignment" to theoretically understand why predictive coding (PC) is more sample-efficient than backpropagation (BP) in neural networks. Their analysis, particularly in deep linear networks, shows that PC learning is more efficient, especially in deep, narrow, and pre-trained models. The study provides analytical expressions and experimental validation, offering insights into optimizing PC for effective learning. AI

IMPACT Provides theoretical understanding for optimizing sample efficiency in neural network training.

    Understanding Sample Efficiency in Predictive Coding

    arXiv:2605.11911v2 Announce Type: replace Abstract: Predictive Coding (PC) is an influential account of cortical learning. Much of recent work has focused on comparing PC to Backpropagation (BP) to find whether PC offers any advantages. Small scale experiments show that PC enable…
