Selecting between ANN, MPLS or LOCAL calibrations

 

What is the best algorithm to analyze pH in soil. I try with MPLS, ANN and LOCAL. Models had been developed with a training set and we check the performance with a test set.

We can see that the performance is almost similar for ANN and LOCAL vs. the MPLS model.

LOCAL models have the advantage that we get the GH and NH values, so we can recalculate removing the high GHs values, that will be marked in red if the test samples would be analyzed in routine.

Sorry for some black cuts in the video.
