Classical shadows of local observables combined with unsupervised ML distinguish phases in the axial next-nearest-neighbor Ising model and Kitaev-Heisenberg ladder, with sample complexity scaling logarithmically in the number of features.
This corresponds to a narrow region around the pure Kitaev limit at ϕ = π 2 , where J = 0 and K = 1

Distinguishing Ordered Phases using Machine Learning and Classical Shadows
