The rate-distortion infimum is attained for lower semi-continuous distortions on locally compact Polish alphabets via one-point compactification for bounded distortions and concentration-compactness for unbounded coercive distortions.
EM's monotonicity and local rate are unified by the spectral operator G = I - DT that equals the missing-information ratio and observed-likelihood Hessian, enabling accelerated local updates.
