BCIwiki (bciwiki.com) — Researchers have introduced EasyBCI, a two-phase large language model agent that plans and executes preprocessing pipelines for six signal types, according to a preprint posted to arXiv on July 31, 2026. The study is a preprint and has not been peer reviewed.
The authors say BCI preprocessing has remained manual, expert-dependent, and poorly reproducible. To address this, a Plan Agent profiles each recording into a text-only Data Fingerprint that never exposes raw data to the model and selects a literature-grounded operator sequence, while an Execution Agent generates, runs, and self-corrects code until quality criteria are met. A quality-gated experience system retains validated strategies as reusable skills, and a domain expert intervenes at two decision gates, retaining human judgement where undetected error can invalidate downstream analyses.
