What is machine learning? How is it transforming our lives and workplaces? What might the future hold? Pedro Domingos of the University of Washington and author of The Master Algorithm talks with EconTalk host Russ Roberts about the present and future of machine learning. Domingos stresses the iterative and ever-improving nature of machine learning. He is fundamentally an optimist about the potential of machine learning with ever-larger amounts of data to transform the human experience.
