RAG-based EEG-to-Text Translation Using Deep Learning and LLMs
A new study proposes a retrieval-augmented generation (RAG)-based method for translating EEG signals into text. This approach aims to improve sentence-level decoding, which has been challenging due to low signal-to-noise ratios in EEG recordings. The proposed pipeline shows a significant improvement over random baseline performance in experiments conducted on EEG data from silent reading.
- ▪The study introduces a RAG-based EEG-to-text decoding pipeline that combines an EEG encoder with semantic sentence embeddings.
- ▪Experiments were conducted using the Zurich Cognitive Language Processing Corpus, which includes single-trial EEG recordings.
- ▪The proposed method achieved a mean cosine similarity of 0.181, representing a 30.45% improvement over the random baseline.

In particular, sentence-level decoding from EEG is difficult due to the low signal-to-noise ratio of these recordings.
