arXiv:2606.29161v1 Announce Type: new Abstract: Predicting tandem mass spectra (MS/MS) from molecular structures represents a central task in analytical chemistry with direct relevance to clinical metabolomics, systems biology, and adjacent disciplines. In this work, we revisit the problem through the lens of object detection on molecular graphs. Molecular fragmentation, a central step in MS/MS prediction, can be approximated as detecting a set of subgraphs (i.e., fragments) and their associated spectral contributions. Existing fragment-based models follow a two-stage paradigm -- first generat
The application of advanced AI techniques, specifically object detection from computer vision, is now mature enough to be applied to complex analytical chemistry problems like mass spectrometry prediction.
Improved mass spectrum prediction can significantly accelerate drug discovery, biomarker identification, and understanding of biological systems, impacting various industries from healthcare to agriculture.
The approach to mass spectrum prediction shifts from traditional fragmentation models to a more robust, AI-driven 'object detection' paradigm, potentially increasing accuracy and efficiency.
