Embodiment Construction
[0080] In order to better explain the present invention and facilitate understanding, the present invention will be described in detail below through specific embodiments in conjunction with the accompanying drawings.
[0081] The main design idea of the present invention is as follows:
[0082] The present invention uses multi-channel sensors to acquire the proportions of different chemical groups in the air at each time period as variables. The data is then preprocessed to get the input of the regressor. The whole regressor is divided into two parts: training and testing. In the training phase, each training sample and the corresponding label will obtain the corresponding number of regression coefficients and auxiliary parameters through several iterations; while in the testing phase, the parameters and regression coefficients obtained from the training are directly used to realize the air quality after multiple superpositions. estimate.
[0083] The air quality detecti...
