ZUNA1.1 pushes EEG AI with 380M parameters
New open-source EEG model handles 30s signals, 4x faster than spline interpolation...
A new arXiv paper introduces ZUNA1.1, a 380M-parameter diffusion autoencoder for flexible EEG signal reconstruction. It handles variable-length sequences up to 30 seconds, any number of EEG channels at arbitrary scalp locations, and can reconstruct arbitrary temporal intervals within channels as well as entire channels. The model performs at least on par with earlier ZUNA1 while being far more flexible across a wide range of reconstruction tasks, and continues to substantially outperform standard methods like spherical spline interpolation, widely used in MNE. ZUNA1.1 is released open source under the permissive Apache 2.0 license.
- ZUNA1.1 is a 380M-parameter diffusion autoencoder for EEG signal reconstruction
- Handles variable-length sequences up to 30s across arbitrary channels and temporal intervals
- Outperforms traditional methods like spherical spline interpolation (used in MNE package)
