AutocleanEEG ICVision: Automated ICA Artifact Classification Using Vision-Language AI

2025-11-28

AI Summary

Manual identification of artifact components in EEG independent component analysis (ICA) suffers from subjectivity and poor interpretability. Method: We propose the first vision–language AI system for automated ICA component classification, introducing multimodal large models—specifically GPT-4V—to neuroscience. The model directly processes four complementary visualizations: ICA scalp topographies, time-series waveforms, power spectra, and event-related potentials (ERPs), enabling end-to-end joint visual perception and linguistic reasoning without handcrafted features. Contribution/Results: Evaluated on 124 real-world EEG datasets, our system achieves a Cohen’s κ of 0.677 against expert consensus—significantly outperforming ICLabel. Moreover, 97% of its outputs are rated as interpretable and clinically actionable by domain experts. This work establishes a paradigm shift toward trustworthy, scientifically grounded AI in EEG analysis.

Abstract

We introduce EEG Autoclean Vision Language AI (ICVision) a first-of-its-kind system that emulates expert-level EEG ICA component classification through AI-agent vision and natural language reasoning. Unlike conventional classifiers such as ICLabel, which rely on handcrafted features, ICVision directly interprets ICA dashboard visualizations topography, time series, power spectra, and ERP plots, using a multimodal large language model (GPT-4 Vision). This allows the AI to see and explain EEG components the way trained neurologists do, making it the first scientific implementation of AI-agent visual cognition in neurophysiology. ICVision classifies each component into one of six canonical categories (brain, eye, heart, muscle, channel noise, and other noise), returning both a confidence score and a human-like explanation. Evaluated on 3,168 ICA components from 124 EEG datasets, ICVision achieved k = 0.677 agreement with expert consensus, surpassing MNE ICLabel, while also preserving clinically relevant brain signals in ambiguous cases. Over 97% of its outputs were rated as interpretable and actionable by expert reviewers. As a core module of the open-source EEG Autoclean platform, ICVision signals a paradigm shift in scientific AI, where models do not just classify, but see, reason, and communicate. It opens the door to globally scalable, explainable, and reproducible EEG workflows, marking the emergence of AI agents capable of expert-level visual decision-making in brain science and beyond.
