GRU models outperform Mamba for brain-to-text decoding

By PulseAugur Editorial · [1 sources] ·

Researchers have investigated the effectiveness of different model architectures and target representations for intracortical brain-to-text systems. The study compared gated recurrent units (GRUs) with selective state-space models (Mamba) and evaluated both phonetic and character-level targets on the Brain-to-Text '25 benchmark. Results indicated that GRUs performed best, with phonetic targets achieving 12.62% PER and character targets reaching 13.39% CER after language model rescoring. The Mamba hybrid models were competitive but did not outperform the GRU baselines. AI

IMPACT This research contributes to the understanding of optimal model architectures and data representations for brain-computer interfaces, potentially improving future assistive technologies.

    Phoneme- vs. Character-Level Targets and Selective State-Space Models for Intracortical Brain-to-Text

    arXiv:2607.26751v1 Announce Type: new Abstract: State-of-the-art intracortical brain-to-text systems pair a neural-sequence phone decoder with an external language model. Two design axes remain underexplored: whether selective state-space models (Mamba) improve on recurrent decod…
