Cash flow prediction model construction method and cash flow prediction method

Abstract

The invention discloses a cash flow prediction model construction method and a cash flow prediction method, and the method comprises the steps: obtaining the original sample data of at least one dimension, and enabling the original sample data of each dimension to be a factor affecting the cash flow; preprocessing the original sample, and constructing a multivariate time sequence based on the original sample to obtain a training sample; and performing training at least one preset machine learning model based on the training sample, and fusing the trained machine learning models to obtain a cash flow prediction model. Therefore, automatic prediction of the cash flow is realized, data of at least one dimension is adopted, a multivariate time sequence is constructed for the data, the complexity of the sample is improved, and the accuracy of model prediction is further improved. In addition, a plurality of trained models are fused, the advantages of all the models are combined, and the prediction accuracy of the cash flow prediction model is further improved.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a method for constructing a cash flow model and a method and device for predicting cash flow. Background technique [0002] The cash stock management of bank outlets is the basis for carrying out cash business. The more cash in bank outlets, the stronger the liquidity, and the worse the profitability; insufficient cash in inventory will lead to the inability to meet the withdrawal needs of customers. Therefore, how to control the inventory of bank outlets Keeping the amount within a reasonable range is a basic problem faced by banks in cash operation and management. [0003] In the prior art, the manual estimation method is usually used to estimate the cash flow. This method has strong subjectivity, relies heavily on the forecaster's own experience, and has low accuracy and efficiency. Contents of the invention [0004] In view of this, the embodiment of the present invention di...
