Domain-specific D-optimal threshold quantizers

Boundary marker: “using determinant Fisher information to design a quantizer” is not itself new.

Several sensor/localization works optimize restricted quantizer thresholds or bit allocation by $\det I$ . Example: Jiang et al. (2026), Direct target localization in USNs with hybrid quantized multi-snapshot measurements: A geometric structure-aided approach.
