Embodiment Construction
[0021] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0022] Such as figure 1 and 2 As shown, the present invention provides a kind of adaboost-based foodborne pathogen Raman spectrum classification model training method, comprising:
[0023] Step S1, smoothing and denoising the Raman spectrum data stream of food-borne pathogens, while keeping the shape and width of the signal in the Raman spectrum data stream of food-borne pathogens after smoothing and denoising unchanged;
[0024] Step S2: Sampling the Raman spectral data stream of food-borne pathogenic bacteria after smoothing and denoising, normalizing, and then performing PCA dimensionality reduction, and calculating each feature in the Raman spectral data stream of food-borne pathogenic bacteria The correlation coefficient re...
