Pretraining Recurrent Networks without Recurrence

Researchers propose Supervised Memory Training (SMT), a novel method for training recurrent neural networks that replaces sequential backpropagation through time with parallel, supervised learning on memory state transitions. By leveraging a Transformer encoder to generate training labels, SMT achieves stable gradient propagation and improved performance on language and sequence modeling tasks without the parallelism constraints of traditional RNN training.
