ML4PSP Seminar May 2023
With a focus on laser-induced breakdown spectroscopy (LIBS) applications on Mars with ChemCam, I have studied various influences on elemental quantification in rocks using a suite of LIBS spectra from almost 3,000 geological standards. Rock spectra are notoriously complex and it is difficult to build robust and accurate predictive models for unknowns on remote surfaces. From this work I have discovered pros and cons of various machine learning methods, effects of data set size and diversity, and compared results to traditional methods. The moral of the story is: the more data, the better!
