Using Reflectance Spectroscopy and Artificial Neural Network to Assess Water Infiltration Rate into the Soil Profile

Figure 3

(a) Measured versus predicted values of logarithmically transformed infiltration rates (IR). Results of cross-validation modeling run on the calibration set (53 samples, second derivative of absorbance run on 48 wavelengths). (b) 10 measured versus predicted IRs of the external test set ( = 11 samples).
