Machine learning is not as easy to apply to finance as it is to a domain that has a lot of structure in it, Vasant Dhar, SCT Capital founder, professor at NYU's Stern School of Business, and director of the PhD program in the Center for Data Science at NYU, told Real Vision's The Interview. He thinks machine learning has been somewhat oversold in that sense. "It's not like you just put in data and magic appears at the other end," he said. "There's a lot of care that has to go into how you formulate the problem, how you create the data, whether you have a process in place." However, he did say that the technology is perfect for higher-frequency trading.
