  1. Mdl-Based Band Selection and Adaptive Penalties for Hyperspectral Image Segmentation

    … minimize the error rate if the scene has certain weak symmetry properties. For example, all boundaries must be equally rough. This is not always satisfied in practice, so we also introduce an MRF with class-pair-conditional (CP) boundary penalties. We segment both synthetic and real images to …

  2. Quantum Trajectories: Metastability, Gauge Freedom and Weak Symmetries

    … under which the trajectory dynamics exhibit a weak unitary symmetry. We then consider under what conditions the joint state of the system and environment exhibit symmetric dynamics, including under various levels of dephasing. We find that the joint dynamics always features a separable symmetry …
