The machine learning algorithm has four choices: NBL, MSL, TDLL, and ODLL. The feature representation (FP) has six options: A, B, C, D, E, and F, where A, B, C, and E have five different window sizes 2, 4, 6, 8, and 10. The 95% confidence interval for each precision value (p) in the table is p ± 0.5∼1.5%.
