Reconstructed EEG windows from BCI Competition IV Dataset 1 using EEGReXferNet

This dataset provides reconstructed EEG windows from BCI Competition IV Dataset 1, created using EEGReXferNet, a lightweight AI framework for EEG subspace reconstruction via cross-subject transfer learning and channel-aware embedding.
The repository for the framework is available on GitHub: https://github.com/ShanSarkar75/EEGReXferNet/

Each subject-specific folder contains reconstructed EEG windows in .npz format.Files are organized by subject, model type (A, B, C, D), and window type:Clean windowsNoisy windows (> ±3.5 σ)Note: Due to GitHub file size limitations, reconstructed EEG windows are shared via FigShare. Users are encouraged to download the relevant files before performing model/data analysis or validation.
