Bridge Seismic Damage Assessment Model Applying Artificial Neural Networks and the Random Forest Algorithm

Table 6

The comparison between the ANN models and the linear regression models of the girder bridges and arch bridges (%). The results demonstrate the difference between the prediction value and the actual value of level zero, level one, and the other levels.

Differences	ANN model		Linear regression model
	Girder bridges	Arch bridges	Girder bridges	Arch bridges
Equal	92.3	88.5	71.9	71.5
One level	5.6	8.2	26.4	27.6
≥two levels	2.1	3.3	1.7	0.9
