Veinasa-TS Soil humidity sensor (transducer) is a soil moisture measuring instrument of high precision and high sensitivity. The sensor adopts the principle of electromagnetic pulse to measure the apparent dielectric constant of the soil, resulting i...
The principle of variable selection in the SPA is that among the remaining variables, the next variable selected should have the highest projected value onto the orthogonal subspace created by the previously selected variables. The maximum wavelength variable of the projection vector was selected as ...
The SPA is a positive characteristic variable selection method designed to find a representative set of spectral variables with a minimum of collinearity [36,37]. The principle of variable selection in the SPA is that among the remaining variables, the next variable selected should have the highest...
