Influence of muscle fatigue on the accuracy of gesture decoding. Class $a$ to Class $a$ means to use Class $a$ datasets as training and testing datasets, and the same goes for Class $b$ to Class $b$, while Class $a$ to Class $b$ means to use Class $a$ datasets as training datasets, Class $b$ as testing datasets, and the same goes for Class $b$ to Class $a$.
