Researchers develop sample selection method to streamline machine learning training. It reduces costly data collection using cheaper proxy options.
Researchers at NIRPY have highlighted the Puchwein algorithm as a sample selection method that can also be used for training and test splitting in machine learning models. This is particularly useful when acquiring calibration samples from physical data is costly and laborious. The Puchwein algorithm works by iteratively eliminating similar samples using the Mahalanobis distance, allowing for the selection of representative calibration samples.
This development matters because it can help improve the efficiency and accuracy of machine learning models, especially in fields where data collection is expensive or time-consuming. By using a cheaper proxy, such as optical or near-infrared data, researchers can reduce the burden of calibration sample collection.
As the use of the Puchwein algorithm becomes more widespread, it will be interesting to watch how it compares to other sample selection methods, such as Honigs sampling or genetic algorithms. Further research may also explore the application of this algorithm in various fields, including chemometrics and spectroscopy.
