qubithubkernel-alignment

Optimizes quantum kernel parameters to maximize centered kernel-target alignment (CKA) — a principled score measuring how well a kernel matrix matches label structure. Uses a parameterized encoding with data-dependent and trainable rotations, optimized via Adam with PennyLane autograd.
