With pre-trained template models plus fine-tuning optimization, very high accuracies can be attained for many meaningful applications — like this recent study on medical images, which attains 99.7% …Clustering17 min readClustering17 min read
Published in Bioeconomy.XYZ·Nov 25, 2022The Wearable Biosensor OpportunityA Unified Design of Consumer Electronics and Biological Assays — What do you get when you cross-fertilize a Fitbit™ step counter with ELISA? A wearable biosensor. I expect that for most readers, the stuff of biological engineering — DNA polymers, proteins, monosaccharides, cells — are rarely thought of in combination with the stuff of electronics engineering — capacitors, serial ports, MOSFETs, accelerometers. And for good reasons.Fundamentals20 min readFundamentals20 min read
