1. A method, comprising:
causing, by a device that includes a processor, one or more spectrometers to perform one or more spectroscopic measurements of an unknown sample;
determining, by the device and based on causing the one or more spectrometers to perform the one or more spectroscopic measurements of the unknown sample, that the unknown sample is an outlier sample by using an aggregated classification model;
determining, by the device, that one or more spectroscopic measurements are not performed accurately based on determining that the unknown sample is the outlier sample; and
causing, by the device, one or more actions based on determining the one or more spectroscopic measurements are not performed accurately.
