Matrix Orthogonalization Technique Boosts Associative Recall in Recurrent Neural Networks
By
at2005
Summary
This article discusses a technique called Matrix Orthogonalization to improve associative recall (AR) in recurrent neural networks (RNNs), aiming to close the gap with transformers on this capability. The work is motivated by domains like long-horizon reinforcement learning where transformers' quadratic attention overhead is prohibitive. The approach focuses on making RNNs competitive for tasks requiring associative recall without sacrificing the efficiency benefits of recurrence.

· 3 pulledTransformers exhibit remarkable associative recall (AR) abilities: attention provides each token direct access to those preceding it, a mechanism that has been hard for other architectures, like recurrent neural networks (RNNs), to match.
But for some domains, we can't afford the quadratic-attention overhead of transformers.
For these kinds of applications, we need to make recurrent neural networks work, but don't want to give up on associative recall.
