Resource Description

A semi-supervised machine learning approach for improving the analysis of tandem mass spectrometry data of peptides. Percolator uses a machine learning technique call a support vector machine to dynamically discriminate between correct and decoy spectrum identifications obtained by database searching. By using our approach, we are able to identify approximately 50% more peptides from a given µLC-MS/MS dataset.
