Caroline Strömberg and Tim Gallaher developed a machine learning and computer vision (ML&CV) tool for automatically identifying grass silica short cell phytoliths (GSSCP). To make this tool better than a human at identifying GSSCP, they asked phytolith researchers to take a test. You can still take this ~10-minute anonymous survey to try to identify 14 […]
