SAMBA: Toward a Long-Context EEG Foundation Model via Spatial Embedding and Differential Mamba
Jiazhen Hong, Geoffrey Mackellar, Soheila Ghane
Long-sequence electroencephalogram (EEG) modeling is essential for developing generalizable EEG representation models. This need arises from the high sampling rate of EEG data and…
EEG-X: Device-Agnostic and Noise-Robust Foundation Model for EEG
Navid Mohammadi Foumani, Soheila Ghane, Nam Nguyen +3
Foundation models for EEG analysis are still in their infancy, limited by two key challenges: (1) variability across datasets caused by differences in recording devices and configu…
SpellerSSL: Self-Supervised Learning with P300 Aggregation for Speller BCIs
Jiazhen Hong, Geoff Mackellar, Soheila Ghane
Electroencephalogram (EEG)-based P300 speller brain-computer interfaces (BCIs) face three main challenges: low signal-to-noise ratio (SNR), poor generalization, and time-consuming…
A Differentially Private Algorithm for Range Queries on Trajectories
Soheila Ghane, Lars Kulik, Kotagiri Ramamohanarao
We propose a novel algorithm to ensure -differential privacy for answering range queries on trajectory data. In order to guarantee privacy, differential privacy mechanisms add n…
