This is a Poster for the NSF CSSI PIs meeting, February 12-13, 2020 in Seattle, WA. The poster describes our project "Machine Learning Innovation Infrastructure", which seeks to support rapid development of machine learning applications in Materials Science and Engineering through (i) easy access to data, (ii) cloud-based tools for application of machine learning, and (iii) support for human and machine accessible and sustainable access to disseminated machine learning models.
