Why Machine Learning Models Often Fail to Learn: QuickTake Q&A

#artificialintelligence

Hedge funds have been in the doldrums and face mounting pressure to justify their fees. Will artificial intelligence come to the rescue? A growing number of hedge funds are putting money behind the idea that a branch of AI called machine learning could provide a way to get back on top. A software program that searches for patterns in more data than even the most sleep-deprived junior analyst could examine, and then tests its hypotheses against even more data. What can satellite shots of mall parking lots tell you when combined with in-store sales data?


Hedge funds test artificial intelligence

Anthony Ledford and his colleagues at Man AHL investment fund spent three painstaking years building a machine-learning model to do something mere mortals often can't: find fresh ideas in an avalanche of data. But even Ledford, chief scientist at the $19 billion Man AHL in London, rolls his eyes when he hears people say that machine learning, a type of artificial intelligence, is going to transform hedge funds tomorrow. To Ledford, a lot of the buzz smacks of hype. The technology is more robust than its predecessors but hardly revolutionary. "There is some real science here, but it's not the way it's been portrayed," said Ledford, who holds a doctorate in mathematics.
