Workshop: Learning Meaningful Representations of Life (LMRL)

Jennifer Wei - Machine Learning for Chemical Sensing


I will present two applications of machine learning for molecular sensing: mass spectrometry and olfaction.

Mass spectrometry is a method that chemists use to identify unknown molecules. Spectra from unknown samples are compared against existing libraries of mass spectra; highly matching spectra are considered candidates for the identity of the molecule. I will discuss some work in using machine learning models to predict mass spectra to expand the coverage of libraries to improve the ability of identifying spectra through mass spectrometry.

The second project will discuss a more natural form of molecular sensing: olfaction. I will discuss some work my team has done in predicting human odor labels for individual molecules, and some of the resulting consequences
