Multichannel Spectral Sensors Combined with Machine Learning for Rapid Identification of Coffee Varieties and Origins

Original Linkhttps://doi.org/10.1016/j.foodres.2025.116501AbstractThe rapid identification of coffee varieties and origins is crucial for ensuring quality control and authenticity in the coffee industry. This study explores the use of an affordable multichannel spectral sensor AS7265X (410 – 940 nm), combined with machine learning techniques, to achieve rapid, non-destructive, and accurate classification of coffee varieties and origins. Spectral … Read more

Renaissance in the Age of AI

A few years ago, people were still discussing whether AI would replace designers. It now seems that AI will indeed take over some repetitive, low-creative design tasks, but it will also bring unprecedented new opportunities. What we need to do is not just draw better than others, but think further, act faster, and reach wider … Read more

The World’s Most Popular Chip Turns 40

(Source: man)In April 1985, a small team at Acorn Computers in Cambridge, UK, began rethinking the concept of processors. Engineers Sophie Wilson and Steve Furber developed the ARM1 (which originally stood for Advanced RISC Machine), a modest chip that contained only 25,000 transistors. The ARM1 powered the BBC Micro, creating a 32-bit processor that emphasized … Read more
