SYSTEMS AND METHODS FOR IDENTIFICATION OF FLUID AND SUBSTRATE COMPOSITION OR PHYSICO-CHEMICAL PROPERTIES

摘要

Techniques for identifying a composition of a target fluid using a set of vectors representing known residue patterns for a two or more fluids including said target fluid is provided. An exemplary method includes storing one or more digital measurements of residue for the target fluid, extracting one or more descriptive features from the measurements; and processing descriptive features to identify the composition of the target fluid. The processing includes using a machine learning algorithm trained with data linking residue morphology to fluid composition. A distance between a vector representing said one or more descriptive features and said set of vectors representing known residue patterns is determined, and a residue is assigned to one or more of the known residue patterns.
