Title:
MODEL UPDATING METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2018/028326
Kind Code:
A1
Abstract:
A model updating method and apparatus, relating to the technical field of computers and used to at least solve the problem of a waste of resources caused by the poor significance or even insignificance of a later model update in two model updates triggered by two adjacent updating triggering points, due to the fact that changes between data features of newly-added data of two adjacent updating triggering points and data features of previous data are non-obvious. The method comprises: acquiring first online service data received within a window where a triggering point to be detected is located; according to the data features of the first online service data, constructing a first feature sequence; determining an association relationship between the first feature sequence and at least one representative slice, wherein the representative slice is a slice of a feature sequence constructed according to the data feature of historical service data; if the association relationship between the first feature sequence and the at least one representative slice satisfies a pre-set condition, updating the current model.
