Abstract: A FCN-based MTS data classification method is disclosed, comprising: generating input conditions according to a parameter of a multivariate Gaussian model and the MTS data; establishing correspondence between the input conditions and data categories of the MTS data via learning ability of an artificial intelligence model; determining at least one corresponding current input conditions according to current MTS of a target object; and determining current data categories corresponding to the current input conditions through the correspondence, and determining data categories corresponding to the input conditions identical to the current input conditions in the correspondence as the current data categories. The parameters of the multivariate Gaussian model corresponding to the MTS data are served as the input conditions, so that the accuracy is guaranteed, while a training speed of an artificial intelligence model is greatly improved, and the higher the data set dimension, the more significant the improvement.
