HMM is closely related to earlier work on the optimal nonlinear filtering problem by Ruslan L. Stratonovich, who was the first to describe the forward-backward procedure.
هذا النموذج يرتبط ارتباطا وثيقا بعمل سابق على "optimal nonlinear filtering problem by Ruslan L. Stratonovich" الذي كان أول من وصف "forward-backward procedure."
