Predicting athletes' performance has relied mostly on statistical data. Besides the traditional data, various types of data, including video, have become available. However, it is challenging to use them for deep learning, especially when the size of the athletes' dataset is small. This research proposes a feature-selection strategy based on the criteria used by insightful people, which could improve ML performance. Our ML model employs features selected by people who correctly evaluated the athletes' future performance. We tested out a strategy to predict the LPGA players' next day performance using their interview video. We asked study participants to predict the players' next day score after watching the interviews and asked why. Using combined features of the facial landmarks' movements, derived from the participants, and meta-data showed a better F1-score than using each feature separately. This study suggests that the human-in-the-loop model could improve algorithms' performance with small-dataset.

预测运动员表现主要依赖于统计数据。除了传统数据,视频等各种类型的数据也变得越来越可用。然而,在大小较小的运动员数据集上使用它们进行深度学习是具有挑战性的。本研究提出了一种基于洞察力人员使用的标准的特征选择策略,可以提高ML的性能。我们的ML模型采用了由能够正确评估运动员未来表现的人选择的特征。我们尝试了一种策略,使用选手面试视频来预测LPGA选手的下一天表现。我们要求研究参与者观看视频后预测选手的下一天得分,并解释原因。 使用反映参与者观察到的面部关键点变化的特征和元数据的组合要比分别使用每种特征具有更好的F1得分。 本研究表明,循环模型可以通过小数据集提高算法性能。
