Deterministic Annealing PCH-EM Algorithm

Initialization-Robust PCH-EM Algorithm for Characterization of DSERN Pixels

Deterministic annealing extension of the PCH-EM algorithm (DA-PCH-EM).

annealing_demo.m - Generates a synthetic dataset and runs DA-PCH-EM for 10^4 randomized starting points. Demo code recreates Figure 2 in arXiv pre-print:
