阈值线性联想网络局部学习规则的有效性

Efficiency of local learning rules in threshold-linear associative networks

Francesca Schönsberg, Yasser Roudi, Alessandro Treves

摘要:

我们推导出阈值线性单元的关联网络的加德纳存储容量,并表明,与赫布学习,他们可以操作更接近这样的加德纳界比二进制networks.This的,甚至超越它在很大程度上是通过稀疏化检索到的模式,我们分析的理论和经验的活动分布。由于通过非局部学习规则(如反向传播)达到最佳容量需要缓慢且神经上难以置信的训练过程,因此我们的研究结果表明,一次性自组织Hebbian学习同样有效。

英文摘要:

We derive the Gardner storage capacity for associative networks of threshold linear units, and show that with Hebbian learning they can operate closer to such Gardner bound than binary networks, and even surpass it. This is largely achieved through a sparsification of the retrieved patterns, which we analyze for theoretical and empirical distributions of activity. As reaching the optimal capacity via non-local learning rules like backpropagation requires slow and neurally implausible training procedures, our results indicate that one-shot self-organized Hebbian learning can be just as efficient.
