Model training method and device, storage medium and electronic equipment

The invention discloses a model training method and apparatus, a storage medium and an electronic device. The method comprises the steps of obtaining a first sample and a first label category to which a transaction intention category corresponding to the first sample belongs under each preset classification level; and inputting the first samples into a plurality of coding layers to obtain first coding results. According to a sequence of classification levels from top to bottom, for each classification level, coding results of coding layers corresponding to all superior classification levels of the classification level and coding results of the coding layers corresponding to the classification level are input into a first decoding layer corresponding to the classification level, and the coding results of the coding layers corresponding to the classification level are input into a second decoding layer corresponding to the classification level; and obtaining a decoding result of the first decoding layer corresp
