Abstract

The invention discloses an SHAP feature attribution method, device and equipment and a readable storage medium. The SHAP feature attribution method comprises the steps: obtaining data to be interpreted, distributing the to-be-interpreted data to an execution end associated with the driving end; broadcasting a preset to-be-interpreted model to the execution end, enabling the execution end to calculate marginal benefit expectations and label expected values corresponding to the sample features in the to-be-interpreted data in parallel based on the to-be-interpreted model; and receiving each marginal benefit expectation and the label expected value fed back by the execution end, and calculating an SHAP result corresponding to the to-be-interpreted data based on each marginal benefit expectation and the label expected value. The technical problem that the model interpretation efficiency based on the SHAP is low is solved.

Description

technical field [0001] The present application relates to the technical field of artificial intelligence of financial technology (Fintech), in particular to a SHAP feature attribution method, device, equipment and readable storage medium. Background technique [0002] With the continuous development of financial technology, especially Internet technology and finance, more and more technologies (such as distributed, blockchain, artificial intelligence, etc.) Requirements, such as the distribution of corresponding to-do items in the financial industry also have higher requirements. [0003] With the continuous development of computer software and artificial intelligence, the application of machine learning has become more and more extensive, and a series of high-performance machine learning models have also been developed, such as random forests, gradient boosting trees, deep learning, etc., but these The internal principles of machine learning models are difficult to underst...
