但這還不夠,科學家總是能想到更奇葩的需求:未來,你的手機也有機會變身「大麻檢測器」了!羅格斯大學健康暨健康政策與高齡研究所(Rutgers Institute for Health, Health Care Policy and Aging Research)研究團隊,調查大麻使用者的「嗨度」,並將其與機器學習技術做結合,試圖打造能準確判斷大麻中毒程度的日常小工具。
註 1:該研究所使用的技術為「Light Gradient Boosting Machine」,是微軟公司以「決策數演算法」(decision tree algorithms)為基礎,於二〇一七年釋出 LightGBM 演算法,用於排序、分類和其它機器學習的任務。
