SZ4D
Machine Learning & Artificial Intelligence
Virtual Workshop

August 2-4, 2023 (9am-11:30am PDT, 12-2:30pm ET-Chile Time) 

Workshop Objectives

To get community input, buy-in, and feedback regarding what AI/ML approaches are most promising, and what specific steps are needed, to achieve SZ4D goals: 1) Connect useful techniques across domains to enable multi-disciplinary science, 2) Determine and prioritize focus areas for future proposals; and 3) Understand community needs for ML/AI training and community software.

Motivation from the SZ4D Implementation Plan

“Given that the initial planning phase of the MCS RCN was focused primarily on physics-based modeling, it will be important to carry out similar efforts for data-driven computational science applications like ML in the next phase of SZ4D  Workshops and other community-building activities are needed to identify community needs, opportunities for open-source software development, and training and educational activities.”

The SZ4D Virtual Workshop on Machine Learning and Artificial Intelligence (ML/AI) will take place August 2-4, 2023, with three sessions focused on different themes. Each session will have three invited speakers (1hr), focused breakouts (1hr), & report back/synthesis (0.5hr). More details about each session and link t register in advance below.
