LBMamba: Locally Bi-directional Mamba
Published in Transactions on Machine Learning Research (TMLR), 2025

We present LBMamba, a locally bi-directional State Space Model block that integrates a lightweight, register-level backward scan within the forward scan to restore a full receptive field without the computational overhead of a secondary global backward pass.
