Expand description

Reconstruction error ‖x − z·m(t)‖ of an encoded coordinate t — the criterion the certified encode minimizes over its candidate charts to pick the GLOBAL basin. m(t) = Bᵀ Φ(t) is the amplitude-1 reconstruction; z is the amplitude. A non-finite reconstruction returns +∞ so it never wins.
