Abstract

The invention relates to the field of block storage systems and artificial intelligence, and discloses a risk prediction model training method and a related device, and the method comprises the steps:obtaining a first financial data set which comprises M pieces of first financial data corresponding to a plurality of first fields; for the first financial data set, vectorizing a plurality of piecesof first financial data associated with each of the plurality of first fields to obtain a plurality of first vectors; determining the correlation between every two first vectors in the plurality of vectors by adopting a preset feature selection algorithm; determining a second financial data set from the first financial data set according to the correlation between every two first vectors; and training a risk prediction model by adopting the second financial data set. By implementing the embodiment of the invention, the training period of the risk prediction model is shortened, and the training complexity is reduced.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular, to a training method and related apparatus for a risk prediction model. Background technique [0002] With the rapid development of emerging technologies, various industries have begun to use deep learning, neural networks, etc. to achieve risk prediction. For example, a risk prediction model can be used to predict corporate default risk. Generally speaking, before realizing the prediction of enterprise default risk through the risk prediction model, the training of the risk prediction model is required. In the prior art, when training a risk prediction model, financial data sets are often used directly. Due to the large amount of data in financial datasets, the training period of the risk prediction model is long and the training complexity is high. SUMMARY OF THE INVENTION [0003] The embodiments of the present application provide a training method and a rel...
