2. Abstract
In this talk, a badminton stroke classification system utilizing wearable devices, mobile platforms, and machine learning techniques will be introduced. The system has two key modules, stroke detection and stroke classification. In the stroke detection module, an algorithm was proposed to detect stroke events and their happening times based on voiceprint features. The accuracy of event detection is 100% in our experiments. To have better classification performance, four classifiers, including the random forest, SMO with Polynomial Kernel, SMO with RBF Kernel, and Naïve Bayes, were evaluated to classify six stroke types based on IMU data. Our results showed that SMO with Polynomial Kernel reaches an average accuracy rate 96.83% and outperforms the other three classifiers.
