The invention belongs to off-line reinforcement learning, and particularly relates to an off-line reinforcement learning method combining generalized advantage estimation and modal decomposition interaction. In order to solve the problems of insufficient track splicing capability and intra-modal interaction and inter-modal interaction of multi-modal information in a track in an off-line reinforcement learning method based on TransFormer, the track splicing capability of a model in an off-line data set is improved by adopting generalized advantage estimation, a modal decomposition interaction module utilizes an encoder-decoder structure, and a mode decomposition interaction module utilizes an encoder-decoder structure, so that the track splicing capability of the model in the off-line data set is improved. And the encoder effectively processes time sequence information in a single mode by utilizing modal internal interaction based on ConvFormer. Relative to this, the correlation between the state and the action is captured based on the interaction between the modes of the TransFormer, so that the characterization capability of the model on the state and action sequence is enhanced. The decoder further fuses multi-modal information by using convolution and cross-attention mechanisms, thereby realizing more accurate motion prediction.
