Model optimization method and device and computer program product

Abstract

The embodiment of the invention discloses a model optimization method and device and a computer program product, and the method comprises the steps: obtaining an image sample set, calling a to-be-optimized target perception model to carry out the image perception of each image sample in the image sample set according to a target image perception task, and obtaining a target perception result of each image sample; calling a reference perception model to perform image perception on each image sample according to the target image perception task to obtain a reference perception result of each image sample; performing differential processing on the target sensing result of each image sample and the corresponding reference sensing result to obtain a differential result of each image sample; according to the difference result of each image sample, carrying out difficult sample mining in the image sample set to obtain one or more difficult samples; and updating the target perception model according to optimization parameters of the target perception model determined through the one or more difficult sample. According to the embodiment of the invention, the sensing capability of the target sensing model can be improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a model optimization method, device and computer program product. Background technique [0002] At present, with the continuous development of computer technology, visual perception technology has been widely concerned; among them, visual perception technology can be understood as a technology that invokes a perception model to perform image perception on images in a scene. In visual perception technology, images in most scenes can be correctly perceived by the perception model, while images in some extreme and rare scenes are easily perceived by the perception model. It can be seen that the perception ability of the existing perception model poor. Based on this, how to optimize the perception model to improve the perception ability of the perception model has become a research hotspot.
