Table 2 Performance of the CNN models for all data

From: P-wave first-motion polarity determination of waveform data in western Japan using deep learning

	250 Hz		100 Hz
	U_CNN	D_CNN	U_CNN	D_CNN
U_human	56.3%	1.1%	56.2%	2.4%
D_human	1.0%	41.7%	2.2%	39.3%
Accuracy	97.9%		95.4%

“U” and “D” indicate Up and Down, respectively, of the P-wave first-motion polarity determined by the CNN models or human experts (e.g., U_CNN means the CNN models determine the polarity to be Up). The number of test data is 12,720 for 250 Hz and 4017 for 100 Hz
