When Suzy Welch walked into the first meeting of the first university course she had ever taught, in the fall of 2022, she looked out onto 20 students. She and the dean of New York University’s Stern ...

Abstract: We derive an algorithm similar to the well-known Baum-Welch (1970) algorithm for estimating the parameters of a hidden Markov model (HMM). The new algorithm allows the observation PDF of ...
