An automated mineral classifier using Raman spectra

A spectroscopic mineral classifier was built using an artificial neural network. Minerals were selected for compositional characterization of igneous rocks. We used two sources of spectral data to ensure the robustness of our classifier. The classifier learned differences in spectra that are hard to perceive by humans.
