To evaluate the performance of a classifier, you should always test the model on invisible data. The eNose company aims to utilize the aeoNose, a portable breath analyzer, to overcome any obstacle that has thus far prevented early detection of lung cancer. Elevated glycolysis leads to increases in lactate and fumarate metabolites resulting in altered VOC abundances in exhaled breath. Answer: Early diagnosis saves lives. Recent research has also shown that a person’s breath could also indicate the presence of cancer. Using 15 (or 21) different compounds for distinction, sensitivity was 71% (80%) with a specificity of 100%.
