Model training improvement method and device

The invention discloses a model training improvement method and device, and the method comprises the steps: obtaining and for a plurality of pieces of to-be-trained data, filling the to-be-trained data into a multi-dimensional data space of a matrix space in a matrix manner, and obtaining a plurality of information regions; inputting the plurality of information areas into the model to obtain a training result of each information area; the training result of each information area is stored in a target area of a matrix space in a matrix mode; generating a model change report based on all the target areas and all the information areas; and determining a related direction of model training according to the model change report, and training the model. The correlation direction of model training is determined through the model change report, the model is trained through the to-be-trained data in the correlation direction of model training, the model does not need to be trained according to the data type of the to-
