TV Professional Baseball Commentary Using Machine Learning



We are working on a project to challenge Japanese Professional Baseball commentary using deep learning and data mining.

Phase 1 involved the learning of data that included in excess of 3 million pitches recorded in official professional baseball pitching data from 2004 to develop a digital sports commentator called Mr. ZUNO.

This system predicts the combination of deliveries, victory (or defeat) and ranking etc. using deep learning, and utilizes data mining to analyze pitching according to player tendencies and the state of play which human commentators have been unable to determine to date.

Looking towards the future, we will adapt this system to sports other than baseball and tackle the development of ways to enjoy sports from a variety of perspectives.
