  • Publication number: 20240029397
    Abstract: The present application discloses a few-shot image recognition method and apparatus, a device, and a storage medium. The method includes: obtaining to-be-recognized images, and constructing an image episode according to the to-be-recognized image, the image episode including a support set and a query set; inputting the image episode into a pre-trained image recognition model, the image recognition model being a few-shot image recognition model based on hard episode training; and calculating a similarity between an image in the query set and each class in the support set according to the image recognition model, and determining the class of to-be-recognized images in the query set according to the similarity.

  • Patent number: 10829715
    Abstract: A high-efficiency supercritical oil extraction method is provided. According to the method, in an early extraction stage, extraction is performed using an extractant along an extraction kettle from top to bottom; in a middle extraction stage, the extraction kettle is longitudinally flipped by 180 degrees, extraction is still performed using an extractant along the extraction kettle from top to bottom; in a later extraction stage, extraction is performed using a conventional extractant along the extraction kettle from bottom to top. Thus, the pressure effect and the critical extraction effect of the critical extractant are simultaneously exerted, thereby greatly improving the extraction efficiency of supercritical oil extraction, shortening the extraction time, and reducing the dosage of extractant, so as to achieve high-efficiency and low-cost oil extraction.
