What is recorded here?
Established an iterative transformation and inequality for maximizing likelihoods in a broad class of probabilistic functions of Markov chains, forming the core of the Baum–Welch estimation procedure.
Source-linked catalogue note. A detailed explanatory guide has not yet been prepared for this entry.
Scientific scope
The record is the exact 1970 Annals of Mathematical Statistics paper. Earlier Baum–Petrie hidden-Markov results, later speech-recognition applications, EM generalizations and software implementations remain separate.
