Brain-CLIPLM: Semantic Compression for EEG-to-Text Decoding

Gang Pan, Huiyuan Tian, Jianyu Zhang, Shijian Li, Xiaoli Yang, Yurui Li

EEG signals encode compressed semantic anchors rather than full sentence structure, making direct reconstruction overparameterized.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

EEG signals encode a compressed set of semantic anchors rather than full linguistic structure, making direct sentence reconstruction overparameterized relative to EEG information capacity; Brain-CLIPLM achieves 67.55% top-5 and 85.00% top-25 sentence retrieval accuracy on the Zurich Cognitive Language Processing Corpus via granularity matching.

C2weakest assumption

The semantic compression hypothesis that EEG encodes only compressed semantic anchors under realistic information constraints, and that the two-stage contrastive-plus-LLM framework aligns decoding complexity with neural capacity without losing essential information.

C3one line summary

Brain-CLIPLM recovers compressed semantic anchors from EEG via contrastive learning and uses retrieval-grounded LLM reasoning to achieve 67.55% top-5 and 85% top-25 sentence retrieval accuracy, supporting the view that EEG encodes semantic content rather than full linguistic structure.
