Abstract

The embodiment of the invention provides a data category attribute determination method and device, a storage medium and an electronic device.The method comprises the steps: inputting target data into a target network model, and obtaining a first feature and a second feature of the target data output by the target network model, wherein the first feature is used for representing the feature mean value of the target data, and the second feature is used for representing the feature variance of the target data; determining a target data category to which the target data belongs and a probability that the target data belongs to the target data category by using the first feature and the second feature; and determining the category attribute of the target data based on the target data category to which the target data belongs and the probability that the target data belongs to the target data category. Through the method and the device, the problem of inaccurate classification of external data in related technologies can be solved, and the effect of accurately classifying the data is achieved.

Description

Technical field [0001] Embodiments of the present invention relate to the field of data processing, in particular, to a method and apparatus for determining a data category attribute, a storage medium, an electronic device. Background technique [0002] In the real world, almost all classification models will face a problem when practical use, need to handle external data that is not a known category, the general classification method will force data to one of the known categories. middle. [0003] Open-set problem not only contains 0 ~ 9 digital categories, but also unknown categories such as A ~ Z, but these unknown categories have no labels, the classifier cannot know these unknown categories The specific category of the image, such as: Whether it is a, these many different category images together constitute a category: unknown category, in the test, we call the background category (Background), and open a classification question: distinguish these 10 Category and reject othe...
