Pretraining Recurrent Networks without Recurrence

arXiv:2606.06479v1 Announce Type: new Abstract: Training recurrent neural networks (RNNs) requires assigning credit across long sequences of computations. Standard backpropagation through time (BPTT) addresses this problem poorly: it is sequential in time, limiting parallelism, and suffers from vanishing or exploding gradients, making long-range associations difficult to learn. We propose Supervised Memory Training (SMT), a method for training nonlinear RNNs that sidesteps recurrent credit propagation entirely by reducing RNN training to supervised learning on one-step memory transition labels

Why this matters
Why now

The continuous drive for more efficient and scalable AI training methods pushes research towards overcoming limitations of existing techniques like BPTT.

Why it’s important

This development proposes a significant technical improvement in training recurrent neural networks, potentially accelerating the development of more advanced AI capabilities.

What changes

The proposed Supervised Memory Training (SMT) could make RNNs more parallelizable and better at handling long-range dependencies, fundamentally altering how they are developed and deployed.
