WebMethods: Model updating by adding new typical samples based on SPXY algorithm and absorbance modification were adopted to improve the model applicability of Huangpi cattle. Results: For model updating, the model correlation coefficient of Enshi buffalo increased from 0.021 to 0.919, with the RMSEP from 8.347 to 2.182. WebThis suggests the proposed algorithm provides a new option to obtain a representative calibration set. Sample subset partition is widely considered in machine learning modeling. An improved sample subset partition method based on a hybrid correlation and diversity x-y distance (HSPXY) is proposed in the framework of SPXY.

SPXY Sample Classification Method and Successive Projections …
WebThe aim of this study is to enhance the classification performance of the back-propagation-artificial neural network (BP-ANN) algorithm for NaCl, NaOH, β-phenylethylamine (PEA), and their mixture, as well as to avoid the defects of the artificial bee colony (ABC) algorithm such as prematurity and local optimization. In this paper, a method that combined an improved … http://www.gpxygpfx.com/CN/abstract/abstract13233.shtml WebThe SPXY algorithm was used to divide the calibration set, and prediction set samples in a 3∶1 ratio. The peroxide value analysis models based on refractive index and absorption coefficient were established by the principal component regression algorithm and partial least square algorithm. thunderbolt legion rome
