Spectrum-based blood species identification instrument and identification method

Abstract

The present invention relates to a method for identifying a species from which blood is derived based on the spectrum data of the blood. The method can be used for fast identifying a species from which a blood sample is derived. According to the implementation steps of the method, a sample data set is divided into a plurality of data sets with relative independence; an identification model is trained for each data set; the capacities of the identification models of the data sets to predict other data sets are compared, so that samples contained in each data set are dynamically adjusted; by means of a circulative iterative process, feature distribution in the spectrum data of the blood sample is de-centralized, so that the wide-area distribution of spectrum feature information is ensured; and the capacity of an overall model to express the spectrum feature information of the blood sample based on the integration of the prediction capacities of the plurality of predictive identification models, and therefore, the accuracy of the prediction of the overall model can be improved.

Description

technical field [0001] The invention belongs to the technical field of pattern recognition, and relates to a method for identifying blood-derived species based on blood spectral data, which can be used for rapid identification of blood sample-derived species. Background technique [0002] With the rapid development of the internationalization of China's pharmaceutical industry, the demand for entry and exit of blood biomaterials is increasing. At present, the Customs judges the blood source species mainly based on two sources of information, one is the blood sample information provided by the declarer, and the other is the inspection results provided by the inspection agency. The authenticity of the former information is difficult to guarantee, while the latter inspection process is difficult It takes a lot of time, and the blood sample may be contaminated by the testing operation, or the blood sample itself may carry pathogenic factors, causing occupational exposure to the ...

Problems solved by technology

At present, the Customs judges the blood source species mainly based on two sources of information, one is the blood sample information provided by the declarer, and the other is the inspection results provided by the inspection agency. The authenticity of the former information is difficult to guarantee, while the latter inspection process is difficult It takes a lot of time, and the blood sample may be contaminated by the testing operation, or the blood sample itself may carry pathogenic factors, causing occupational exposure to the testing personnel

Therefore, although the biochemical method has high detection accuracy, it is inconvenient to be used in customs and other occasions. Therefore, it is necessary to propose a more convenient detection method. The relevant research results show that the spectral detection method has the potential to solve this problem.
