KLASIFIKASI TALENT SCOUTING RENANG MENGGUNAKAN HYBRID LOGISTIC REGRESSION DAN ALGORITMA GENETIKA
Talent identification (Talent Scouting) in swimming is a crucial stage in long-term athlete development; however, selection processes that rely on subjective judgment may lead to bias. This study aims to develop a more objective classification model for identifying potential swimming athletes using a Machine Learning approach. The dataset consists of 100 records with 13 variables, including anthropometric, biomotor, and target potential variables. The method applied is Logistic Regression optimized using Genetic Algorithm for feature selection. Logistic Regression without feature selection achieved 80% accuracy, while the hybrid approach improved accuracy to 90%. The best feature subset was [1 1 0 0 0 0 1 1 1 1 0 1] with a fitness value of 0.7, obtained using C = 10, liblinear solver, population size of 35, 30 generations, a crossover rate of 0.5, and a mutation rate of 0.04. This fitness value was obtained from one particular run and may vary in subsequent runs due to the stochastic nature of the Genetic Algorithm. Overall, feature selection optimization significantly improved classification performance in swimming talent identification.
