About Workshop:
This intensive 3-day workshop explores the cutting edge of AI-driven brain–computer interfaces, focusing on Transformer architectures for EEG motor imagery decoding. Participants will learn how to clean and structure noisy brainwave signals using MNE-Python, translate attention-based Transformer models from NLP into time-series neural decoding, and train deep learning pipelines that classify left vs right motor imagery commands.
Designed for researchers, neuroscientists, and AI practitioners, the workshop blends neurophysiology with modern deep learning—delivering a complete workflow from raw EEG recordings to interpretable attention-based BCI outputs.
Aim: To equip participants with hands-on skills to preprocess EEG data, build Transformer-based deep learning models, and simulate motor imagery brain–computer interface (BCI) classification workflows.
Workshop Objectives:
-
Understand the physiological basis of motor imagery and why EEG signals are challenging for AI.
-
Preprocess raw EEG data using filtering, epoching, and artifact removal (ICA).
-
Implement Transformer Encoder architectures for multi-channel EEG time-series data.
-
Train deep learning models for motor imagery classification tasks.
-
Interpret attention maps to extract neurophysiological insight from model decisions.
-
Build an end-to-end EEG-to-command simulation pipeline for BCI research.
