<![CDATA[This research aims to develop an analytical approach in classification statistics. The proposed approach is the use of machine learning combined with optimization effects. Considering the urgency of research related to exploring the best methods to apply to sports data. This study proposes a novel framework by combining the clustering results of random forest from the k-means method with the bat algorithm optimization to enhance performance prediction in the case of athlete prediction. The proposed method aims to explore data by comparing the quality of classification results in random forest machine learning, extremely randomized trees, and support vector classification methods. We conducted a case study on primary data with 200 respondents from Surabaya State University and the East Java National Sports Committee. The accuracy found in this study indicates that the best approach based on the performance evaluation metric of the proposed approach is the random forest clustering results from the k-means method with bat algorithm optimization, which provides the best accuracy value compared to other machine learning approaches at 81.25%. This research offers a novel machine-learning–optimization framework that significantly improves athlete performance prediction by integrating k-means clustering, random forest, and bat algorithm optimization. The approach provides higher accuracy than conventional classifiers, enabling more data-driven decision-making for talent identification and sports analytics in Indonesia.]]>
