Learning in the Recurrent State: Gradient Descent with Linear Recurrent Networks

arXiv:2410.11687v3 Announce Type: replace-cross Abstract: Linear recurrent networks (LRNNs) offer linear-time sequence modeling, but standard recurrent updates do not directly expose the supervised products needed for in-context gradient descent. We propose a sufficient constructive inductive bias for LRNNs: equip a diagonal recurrent state with multiplicative readout and a short sliding-window cross-product self-attention update. The resulting architecture, Gradient-based Recurrent In-context Learner (GRIL), can implement minibatch gradient descent on a task-specific linear predictor during a

Why this matters
Why now

The continuous drive for more efficient and interpretable AI learning architectures, especially for sequential data, is leading researchers to explore novel recurrent network designs.

Why it’s important

This development could lead to more robust and resource-efficient AI models capable of in-context learning, impacting the development and deployment of advanced AI systems.

What changes

The proposed GRIL architecture offers a potential pathway to implement gradient descent more directly within recurrent networks, enhancing their learning capabilities without relying on traditional backpropagation through time.
