Abstract Scope |
In view of the paradigm shift towards data-driven research in materials science and engineering, handling large amounts of data becomes increasingly important. The applying FAIR data principles emphasize the importance of metadata describing datasets. We propose a novel data processing and machine learning pipeline to extract metadata from micrograph image files, then combine image data and their metadata for microstructure classification with a deep learning approach compared to a classic machine learning approach. The pipeline consists of a metadata extractor followed by transfer of both metadata and TIF image files into readable formats and an encoding step for the metadata. Image data is processed using a feature extractor such as ResNet50 or VGG16 as a backbone, followed by several dense layers, and then combined with processed metadata in a concatenating layer. In this use case, the impact of metadata strongly depends on the machine leaning approach and the model hyperparameters. |
