Stabilization of affine approximations across comparable scales
- theorem
OAI.PolycyclicRecognition.affine_scale_labels_and_offsetsline 16Source documentation
Mixed concentration and the exact chart transition stabilize the finite labels. The offsets are compared in the physical source-scale normalization.
