Rethinking the Fully Hyperbolic Vision Transformer in Polar Coordinates
Ahmad Bdeir, Niels Landwehr
Hyperbolic space can embed intrinsic hierarchies in data with low distortion due to the exponential growth of volume with distance from the origin. However, current Lorentz transfo…
LAtte: Hyperbolic Lorentz Attention for Cross-Subject EEG Classification
Ahmad Bdeir, Johannes Burchert, Tom Hanika +2
Electroencephalogram (EEG) classification plays a key role in medical diagnosis and brain-computer interfaces, but remains challenging due to low signal-to-noise ratios and high in…
HexFormer: Hyperbolic Vision Transformer with Exponential Map Aggregation
Haya Alyoussef, Ahmad Bdeir, Diego Coello de Portugal Mecke +3
Data across modalities such as images, text, and graphs often contains hierarchical and relational structures, which are challenging to model within Euclidean geometry. Hyperbolic…
