Machine learning (ML) and artificial intelligence (AI) are critical instruments that can improve decision making and fasten the pace of research. They can help automate processes, identify novel patterns, and generate predictions. Although AI and ML are constantly evolving and improving, they have the potential to completely transform the technology landscape. At CTSEP, the AI/ML group is focused on leveraging the power of data to drive impactful solutions in the areas of clean energy transition, air quality, and climate action. We develop automated data pipelines to curate datasets and apply advanced data analytics and AI/ML algorithms to extract patterns and support key decisions in these domains.
