Survival analysis of volcanic eruption duration • Build first general model of eruption duration with survival (time-to-event) analysis using machine learning methods (e.g., Random Survival Forests) • Mine data from >10k scraped narrative descriptions of eruptions using NLP Clustering analysis of crystal cargo • Train, test, and optimize clustering models (e.g., GMM) for multidimensional datasets that constrain physical and chemical properties of magmatic domains New method for processing infrared spectra • Increase accuracy and uncertainty estimations during analysis of spectral data by Principal Component Analysis of background spectra
