Classification: CPC A  G | IPC A  G

Claim 10:
11. An apparatus for estimating a concentration of an analyte, the apparatus comprising:
a processor configured to:
obtain a plurality of in vivo estimation spectra;
generate a plurality of noise detection models by varying a number of principal components from among the plurality of in vivo estimation spectra;
compare the generated plurality of noise detection models with a plurality of concentration estimation models for each number of principal components, wherein each of the plurality of concentration estimation models uses a different number of principal components than another of the concentration estimation models;
extract a noise spectrum and a concentration estimation model for use in estimating the concentration of the analyte based on the comparison;
update the extracted concentration estimation model based on the extracted noise spectrum; and
estimate the concentration of the analyte by using the updated concentration estimation model and an in vivo estimation spectrum from among the plurality of in vivo estimation spectra,
wherein the processor is configured to:
determine a correlation coefficient for each number of principal components by comparing the generated plurality of noise detection models with the plurality of concentration estimation models for each number of principal components.
