Transcutaneous Analyte Measuring Methods (TAMM), phase 2

The primary objectives of the first quarter of Phase 2 TAMM were the following: the design of a near infrared (NIR)-800 photodiode array spectrometer, two of which would be used in clinical testing during 1992; the development of advanced pattern recognition software for analyzing the data collected with the spectrometer; and the establishment of an ongoing, internal test program with the B1-102 infrared analyzer. The major effect during the first three months of the project was in developing the analytical software NETGEN. NETGEN is a set of analytical programs that combine the best features of neural networks and genetic algorithms. Artificial neural networks (ANNs) are a form of distributed parallel processing of information that attempts to simulate the human brain. For application in TAMM, ANNs are an alternative to previous pattern recognition methods used for predicting blood analyte concentrations from NIR spectra.
