Abstract

The embodiment of the invention provides an object classification method and device, and relates to the technical field of data processing, and the method comprises the steps: obtaining various typesof features of all objects; for each type of characteristics, calculating the characteristic similarity between the types of characteristics of every two objects; performing fusion processing on the feature similarity corresponding to every two objects to obtain the object similarity between every two objects; clustering each object according to the obtained object similarity to obtain a clustering result; and for each category in the clustering result, determining the category of the category according to the attribute of the object contained in the category. When the scheme provided by the embodiment of the invention is applied to object classification, the accuracy of classification processing results of the objects can be improved.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to an object classification method and device. Background technique [0002] Since the same object has different characteristics when viewing the same object from different angles, when classifying objects based on the characteristics of the object, it is necessary to perform fusion processing on different characteristics of the object, and fuse the different characteristics of the same object into a total feature. Objects are then classified according to their general characteristics. [0003] In the prior art, each feature of an object can be represented by a feature vector. In this way, when performing fusion processing on each feature of an object, the feature vectors corresponding to each feature of the object are sequentially connected end to end to form a feature vector, which is used as the total of the above objects. The eigenvectors, that is, the eigenvectors corr...
