Methods and systems for polymeric fingerprint analysis and identification

Abstract

An example method includes receiving training data for training of a machine learning model. The training data includes a plurality of pairs of datasets. Each of the pairs of datasets includes a reference dataset and a sample dataset. The reference dataset is indicative of first results of a first plastic sample analysis and the sample dataset is indicative of second results of a second plastic sample analysis. Each of the pairs of datasets further includes an indication, for each of the pairs of datasets, that features of the sample dataset and the reference dataset are a match. The method further includes training a machine learning model based on the training data to determine matches between datasets. The method further includes receiving a new sample dataset. The method further includes determining, using the trained machine learning model, that the new sample dataset matches another dataset.
