The embodiments of the invention disclose an information processing method and device. The method includes the following steps: determining a processing result of input information processed by a machine learning model, wherein the processing result is a classification predicted value or a regression predicted value; determining variables involved in the processing result among variables in the machine learning model; calculating the contribution of the variables involved in the processing result to the processing result; and outputting interpretation information of the processing result according to the variables involved in the processing result and the contribution. White box interpretation can be carried out on the processing result of the machine learning model by using the information processing method and device. Therefore, the method and device can improve the interpretability of the machine learning model, thereby helping to correctly guide model optimization direction and helping to reduce the waste of processing resources required by model optimization.
Description
technical field [0001] The present application relates to the technical field of computer software, in particular to an information processing method and device. Background technique [0002] With the rapid development of computer technology and Internet technology, many transactions can be conducted online, which brings convenience to users, but also brings more risks to users' accounts. [0003] At present, the logistic regression model is generally used to describe account risk. This model is highly interpretable, but it is only suitable for training small-scale features, and its accuracy and coverage cannot meet the needs of many businesses. [0004] In response to this problem, in the prior art, a machine learning model has been tried for large-scale features, and the accuracy and coverage have been improved. However, due to the poor interpretability of the machine learning model, it is difficult to interpret the model processing results. , which in turn may lead to a ...
