Similarity Measures of Mass Spectra in Hilbert Spaces

Abstract

Mass spectrometry (MS) is an analytic tool for measuring mass-to-charge ratios of molecules or molecular fragments. It is often used to identify and classify compounds. A mass spectrometer measures the mass of molecules and produces a signal proportional to the number detected fragments, thus, intensity can be interpreted as a function of mass-to-charge. One objective in mass spectrometry is distinguishing compounds using their measured mass spectra. In this technical report we describe the mathematical machinery required to compute a new similarity measure posed in a Hilbert space.
