Classical Models Match or Exceed Shallow Variational Quantum Circuits on Vision Benchmarks
Christopher Fulton, Irene Tsapara, Lawrence Fulton
Quaternion-valued neural networks and variational quantum circuits (VQCs) both derive local transformations from geometry, yet their performance on classical super…

Hypercubes, Hyperplanes, and Constraint-Induced Complexity Collapse in Atomic Concept Learning
Irene Tsapara
We revisit higher-arity atomic concept learning through the geometry of hypercubes and hyperplanes of ground instances. Our starting point is the observation that the ambient r-dim…

Beyond Lipschitz Continuity and Monotonicity: Fractal and Chaotic Activation Functions in Echo State Networks
Rae Chipera, Jenny Du, Irene Tsapara
Contemporary reservoir computing relies heavily on smooth, globally Lipschitz continuous activation functions, limiting applications in defense, disaster response, and pharmaceutic…
