If you&#039;ve ever trained a machine learning model from physical data, you know that acquiring calibration samples may be costly and laborious. If you have a cheaper proxy, for instance optical or near-infrared #spectroscopy as a not-so-random example, you can use that proxy to pre-select the samples to be used for calibration.And if you already have all of your samples, you can still use this method to select the training set.The algorithm was proposed by G Puchwein many years ago.
