一篇新论文提出了前向-前向（FF）学习算法的似然比解释，认为其核心组成部分并非单纯的启发式方法。该研究认为，定义为激活值平方和的标量善意度量，是似然比检验的充分统计量。该框架扩展到各向异性和重尾分布，产生了广义的善意度量，并解释了除法归一化等现象。 AI
影响 为理解和潜在改进前向-前向学习算法提供了理论框架。

善意衡量什么？前向-前向学习的似然比解释
arXiv:2607.12501v1 Announce Type: cross Abstract: The Forward-Forward (FF) algorithm trains each layer locally, so that a scalar goodness - the sum of squared activations - is high on real inputs and low on contrastive ones, with activations normalized between layers. Both choice…
