Abstract

The invention discloses a data processing method and system. The method comprises the following steps: acquiring acquired data; processing the collected data by using a deployed data processing model to obtain a processing result of the collected data, the data processing model being used for inputting the collected data into a feature extraction model to obtain a target feature, and inputting the target feature into an adaptive model to obtain a processing result; under the condition that the processing result meets the preset processing condition, updating parameters of the self-adaptive model based on the collected data, and keeping the parameters of the feature extraction model unchanged. According to the method and the device, the technical problem that the processing effect is reduced due to model degradation of a data processing model after online deployment as time goes by in related technologies is solved.

Description

technical field [0001] The present application relates to the field of data processing, and in particular, to a data processing method and system. Background technique [0002] In the field of traffic intelligent perception, vehicle target recognition, tracking and abnormal event discovery can be carried out based on deep learning methods. However, due to the common existence of concept drift in the field of machine learning and deep learning, the model after going online will degenerate over time. , the model effect gradually decreases. [0003] For the above problems, no effective solution has been proposed yet. Contents of the invention [0004] The embodiment of the present application provides a data processing method and system to at least solve the technical problem in the related art that the data processing model after online deployment degenerates over time, resulting in a decline in processing effect. [0005] According to an aspect of the embodiment of the pr...
