1. A system for estimating blood analyte concentration comprising:

  • a sensor comprising;

    a plurality of light sources configured to operate at different wavelengths; and

    a detector configured to generate signals based on light from the plurality of light sources; and

    a monitor coupled to the sensor configured to;

    receive the signals generated by the detector;

    determine the different wavelengths at which the plurality of light sources operate;

    select a support vector regression function for the different wavelengths at which the plurality of light sources operate;

    estimate blood analyte concentration using the selected support vector regression function in a support vector regression analysis of the received signals; and

    output the estimated blood analyte concentration.
