Accelerating Feedstock Optimization Using Computer Vision, Machine Learning, and Data Analytic Techniques

Thomas Han | 19-SI-001

Executive Summary

We are using computer vision, machine learning, and data analysis approaches to identify critical attributes of manufacturing feedstock materials, including those for advanced manufacturing, and then correlating those attributes to component performance to develop a system for predicting the performance of batches of materials. This new capability will significantly shorten feedstock-optimization cycles and accelerate the overall qualification and deployment process.
