We are happy to announce and welcome you this year to an online seminar in place for the BiGmax workshop on Big-Data-Driven Materials Science. We were enlightened by your interest in the workshop back then in April. With the global Covid19 pandemic now, the online workshop will be slightly shorter. Currently, two topical sessions are planned with a half-day online seminar for each. One session will be on machine learning and image processing for materials science data. The other session will be on machine learning for and on the development of ab-initio methods. Each session will contain live talks and posters presentations. Aligned with the mission of BiGmax, the workshop will connect materials scientists with physicists, and experts for machine learning, scientific computing, and data science.We will contact all participants who had originally planned to join and contribute to the workshop. We will send an email invitation to every single one of you with the program and the details on how to participate. With that we hope to reconvene online this year and are very much looking forward to hearing, discussing, and learning from your contributions.
