First Claim
1. A method for identifying at least one of a physico-chemical property or composition of a target fluid using a set of vectors representing known residue patterns for a two or more fluids including said target fluid, comprising:
- acquiring one or more digital measurements of residue for said target fluid;
extracting one or more descriptive features from at least one of said measurements; and
processing one or more of said descriptive features to identify said at least one physico-chemical property or composition of said target fluid from said at least one of said measurements;
wherein said processing includes using a matching algorithm or a machine learning algorithm trained with data linking residue patterns to fluid composition or physico-chemical properties.

Abstract
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.

10. A method for identifying fluid composition data, comprising:
-
acquiring one or more digital measurements of liquid residue; extracting one or more descriptive features from at least one of said measurements; and processing one or more of said descriptive features to classify said at least one measurement; wherein said processing includes using an unsupervised and trained machine learning technique, and identifying patterns common to several measurements in a residue dataset, if any, and grouping similar residues into clusters without labeled data, such that each cluster, and each of the similar residues grouped therein, corresponds to a distinct visual pattern. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. A system for identifying at least one of a composition or a property of a target fluid using a set of vectors representing known residue patterns for a two or more fluids including said target fluid, comprising:
-
one or more memories storing multimedia data; one or more processors coupled to said one or more memories; a detection device configured to capture a measurement of residue for said target fluid on a substrate, coupled to said one or more processors and said one or more memories so as to store said measurement in said one or more memories; and a computer readable medium containing digital information coupled to said one or more processors, said digital information comprising a machine learning algorithm trained with data linking residue morphology to fluid composition or physico-chemical properties, where when executed said digital information causes said one or more processors to; extract descriptive features from said measurement obtained from said detection device, determine a distance between a vector representing said one or more descriptive features and said set of vectors representing known residue patterns, and assign the fluid residue to one or more of the known residue patterns that minimizes said distance. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28)
