Abstract
Investigators publish new report on Machine Learning. According to news reporting from Dunedin, New Zealand, by NewsRx journalists, research stated, “Coffee is a target for geographical origin fraud. More rapid, cost-effective, and sustainable traceability solutions are needed.” Financial support for this research came from University of Otago. The news correspondents obtained a quote from the research from the University of Otago, “The potential of hyperspectral imaging-near-infrared (HSI-NIR) and advanced machine learning models for rapid and non-destructive origin classification of coffee was explored for the first time (ⅰ) to understand the sensitivity of HSI-NIR for classification across various origin scales (continental, country, regional), and (ⅱ) to identify discriminant wavelength regions. HSI-NIR analysis was conducted on green coffee beans from three continents, eight countries, and 22 regions. The classification performance of four different machine learning models (PLS-DA, SVM, RBF-SVM, Random Forest) was compared. Linear SVM provided near- perfect classification performance at the continental, country, and regional levels, and enabled a feature selection opportunity.” According to the news reporters, the research concluded: “This study demonstrates the feasibility of using HSI-NIR with machine learning for rapid and nondestructive screening of coffee origin, eliminating the need for sample processing.”
