Along with well-annotated datasets, the platform provides users with in-depth tutorials on how to download, import, handle, and train various ML models. Many of the LC-IM-MS data types require certain, sometimes complicated, preprocessing steps in order to be fully compatible with ML frameworks. For this reason, we believe it to be crucial to provide guidelines on these processes to ultimately lower the entry barriers for new users to the field. Tutorials on ProteomicsML can be attribute-or dataset-specific, allowing new tutorial submissions to focus on the direct interactions with specific ML models or methodologies, or to focus on a certain aspect of data preprocessing.
