Abstract

The invention discloses a model training method and device, a prediction method and device, a data processing device and a medium. The network model training method comprises the following steps: acquiring original data information of a historical sample; carrying out feature extraction on the original data information to obtain historical features, and carrying out transformation processing on the historical features to obtain historical feature vectors; utilizing the historical feature vector to generate a simulation feature; combining the simulation features with historical features to serve as a training feature set, and training a deep neural network model after feature transformation; simulation data is generated through the deep learning model by utilizing real historical data, theproblem of lack of samples is solved, the deep neural network model is trained by combining the historical data and the simulation data so as to predict the data, and the accuracy of data prediction can be effectively improved.

Description

technical field [0001] The present invention relates to data processing technology, in particular to a model training method and equipment, a prediction method and equipment, data processing equipment, and a medium. Background technique [0002] At present, data prediction technology is more and more widely used. [0003] However, in the case of too few historical samples, how to train a suitable deep neural network model for accurate data prediction is an urgent technical problem to be solved. [0004] For example, the movie box office prediction technology used to predict the movie box office before the movie is released is also gradually developed to provide reference and support for video companies in the purchase of movie copyrights, so as to facilitate the estimation of the rate of return and effectively control the investment. In addition, it can also provide reference and support for the marketing and promotion of the film market. For example, different ways of adve...
