Table 9. Comparison of the training time of the two classifiers.

Test condition	Training time of one period	U(ms)	D(ms)	Increment Rate(%)
All feature layer are the same Increasing the RBM layers from 1 to 8	Average time	1290	1595	23.64
	Total time	9761	12235	25.35
RBM layer is fixed Increasing the feature layers from 1 to 6	Average time	1089	1317	20.94
	Total time	6135	7574	23.46

Note: U refers to the unsupervised classifier and D refers to the dynamic supervised classifier.
