Matrix Orthogonalization Improves Memory in Recurrent Models

Transformers 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. One example is long-horizon RL, in the style of Dreamer. For ...
