Embodiment Construction

[0064] The present invention will be further described below in conjunction with specific embodiments.

[0065] The present invention selects , , , , ,,,,,,,,,,,,,,, There are more than 800 kinds of standards, and each standard generates 1,000 marks as simulation data. The weights of the two features of matching times and feasible standard size are both 0.4, and the number of standards and the length of marks after length screening The standard weight is 0.05, and the weight of the feature length of the function rule is 0.1, that is, the weight vector is (0.4, 0.05, 0.05, 0.1, 0.4). The number of clusters is chosen to be 5. After the analysis of the logo recognition system, the five characteristics of each logo are obtained: matching times, logo length, length-filtered set, function rule byte length, and feasible standard set. The maximum and minimum values ​​of each standard are counted, as shown in Table 1. Use min-max normalization to normalize the training set to the [...

Abstract

The invention discloses a high-efficiency internet of things identifier code division method. The method comprises the steps that 1) multiple features used for internet identifier code division are selected, and a weight value is set for each feature; 2) normalization processing is performed on the selected features; 3) the selected code identifier samples are clustered, and the weight value acts as the coefficient of a measure component in a measure function of the selected clustering algorithm; 4) weighted calculation is performed on the features of each clustering center so that the score of the corresponding cluster is obtained; and 5) multiple features which are the same with those of the step 1) are extracted from the code identifier as for the code identifier to be divided, then similarity with each clustering center in the step 4) is calculated, and the code identifier to be divided is allocated to the most similar category. Code division speed is substantially enhanced under the condition of guaranteeing certain accuracy.

Description

technical field [0001] The invention relates to an efficient identification code division method of the Internet of Things, belonging to the technical field of computer networks. Background technique [0002] In recent years, IoT-related technologies have become the strategic commanding heights of the world's economic and technological development. Various standard agencies and organizations have released various IoT logo standards, resulting in a chaotic IoT logo system and uneven logo quality. [0003] At present, the algorithms for identifying various IoT logos have a relatively high recognition speed. After research, it is found that standard conflicts are often unavoidable in the logo recognition process; for organizations with standards, the generation of high-quality logos is crucial to the promotion of such standards. At the same time, for countries that manage many standards, an evaluation system is needed to identify excellent signs in a standard. If the proporti...
