A Unified Geometric Framework
Krish Pandya & Vignesh Vembar
This presentation demonstrates how functional analysis provides a unified geometric language for understanding two seemingly different domains: signal processing and hyperbolic deep learning.
Establishes that image compression (DCT) and analytic signal theory (Hilbert transform, AM-FM decomposition) are instances of orthogonal projection onto closed subspaces of L²(𝕋).
Develops the Riemannian geometry of the Poincaré ball, proving that hyperbolic neural networks naturally encode hierarchical structure through their metric tensor.
