Interactive modeling method and device for decision tree model, equipment and storage medium

Abstract

The invention discloses an interactive modeling method and device for a decision tree model, equipment and a storage medium. The method comprises the steps of acquiring the decision tree model to be operated and an operation task for operating the decision tree model; operating the decision tree model according to the operation task, and determining model information to be calculated according tothe operated decision tree model; distributing the calculation task of the model information to each distributed execution machine connected with the local equipment, so that each distributed execution machine executes the calculation task according to respective local data; and obtaining model information according to the calculation result of each distributed execution machine, and visually outputting the operated decision tree model and the model information. According to the invention, the interactive modeling of the decision tree model is carried out by combining the plurality of distributed actuators storing the training data of the decision tree model, so that the problem that the interactive modeling mode based on a single machine cannot carry out modeling by utilizing massive training data stored in a distributed manner is solved.

Description

technical field [0001] The invention relates to the field of artificial intelligence, in particular to an interactive modeling method, device, equipment and storage medium of a decision tree model. Background technique [0002] Due to the good interpretability of the decision tree model, the decision tree model is widely used in many fields. For example, financial institutions use the decision tree model for risk credit modeling. Usually, the modeling method is not simply to use machine learning training to generate a decision tree, but to use interactive model building to visualize the modeling process of the decision tree model. The node splitting rules can be manually set, so that The decision tree grows according to predetermined rules, and the modeler repeatedly interacts and observes the effect until a decision tree model that meets expectations is obtained. [0003] At present, common interactive modeling tools are based on single-machine operation, such as the widel...
