赛马被视为机器学习排名问题,涉及118万匹赛马

一个名为Hoofs的个人项目被开发出来,旨在将赛马视为一个机器学习排名问题,重点关注英国和爱尔兰的比赛。该项目汇编了大约118万条历史赛马记录以及每匹赛马约1700个潜在信号的特征库。模型估计胜率和名次概率,并通过前向验证按时间顺序进行评估,以防止未来信息泄露。虽然仅模型获胜的AUC约为0.729,但市场基准显示出更强的AUC,约为0.790,这凸显了提取未反映在市场价格中的信息的挑战。 AI

影响 展示了机器学习排名和前向验证在复杂、现实预测问题中的应用。

排序理由 该项目描述了一个将机器学习技术应用于特定领域(赛马)的个人项目,并展示了结果,符合研究类别。[lever_c_demoted from research: ic=1 ai=0.7]
