Hedge Fund Analysts Use Deep Learning To Diagnose Heart's Condition

Two quantitative analysts using artificial intelligence in an online data science competition showed they could diagnose heart disease about as accurately as doctors. Qi Liu and Tencia Lee, hedge fund analysts and self-described "quants," built the winning algorithm in the competition, which could find indicators of heart disease. The online data contest challenged participants to develop machine algorithms that could measure cardiac volumes from MRIs provided by the National Heart, Lung and Blood Institute. Mr. Liu and Ms. Lee didn't know each other before they won the competition, beating out more than 1,390 algorithms. They met each other in a forum on the Kaggle site, where the competition was hosted over a three-month period.
