1. A method comprising:
generating a measurement model at surface prior to storing the measurement model in memory disposed within a downhole tool, wherein generating the measurement model includes building an uncompressed measurement model and compressing the uncompressed measurement model to generate a compressed measurement model for storage in the memory;
storing the compressed measurement model in the memory;
moving the downhole tool from a first subsurface location to a second subsurface location in a borehole defined by at least one formation;
accessing the compressed measurement model in the memory;
performing a first measurement using a sensor of the downhole tool operated according to a first parameter set while the sensor is positioned subsurface within the borehole;
determining, by a processor disposed within the downhole tool, an optimal parameter set for operating the sensor of the downhole tool using the compressed measurement model and the first measurement while each of the processor, the sensor, and the memory is positioned subsurface within the borehole, wherein the first parameter set and the optimal parameter set are different; and
performing a second measurement using the sensor of the downhole tool operated according to the optimal parameter set while each of the sensor, the processor, and the memory is positioned subsurface within the borehole.
