Abstract: The present disclosure provides a retrieval and push method based on a fine art image tag, including the following steps: establishing a tag model database: training different tag contents with training samples of different subjects and different categories, and categorizing the training samples in the database according to knowledge point tags to obtain the tag model database; retrieval and push: uploading fine art work image samples to the trained tag model database, then extracting knowledge point tags of the fine art work image samples, retrieving associated fine art works, and then pushing the associated fine art works; real-time updating: recording knowledge point tags of input fine art work image samples by the tag model database in real time, and establishing a common tag and a model, and subsequently increasingly pushing contents relevant to the common tag; and generating a user portrait.

Abstract: Provided are the compound shown in general formula (I) or a stereoisomer, a deuterated compound, a solvate, a prodrug, a metabolite, a pharmaceutically acceptable salt, or co-crystal thereof, an intermediate thereof, and a use thereof in EGFR-related diseases such as cancer.

Abstract: Some embodiments of the present disclosure provide methods, devices, computer-readable storage mediums for detecting a signal light. The method may include obtaining a first image and a second image previous to the first image in time sequence, wherein both the first image and the second image include a same target signal light; determining, based on the first image, a first state of the target signal light in the first image; determining, based on the second image and the first image, a second state of the target signal light in the first image; and determining, based on the first state and the second state, a target state of the target signal light at a time point when the first image is captured.
