Your bird sightings can influence more than just the birding and conservation worlds. eBird checklists are a quintessential example of ‘Big Data’—a massive dataset, chock full of patterns, that contains myriad opportunities to explore exciting questions in fields like statistics or machine learning. Giles Hooker, Associate Professor in the College of Agriculture and Life Sciences at Cornell University, has been using eBird data to understand inherent biases in predictive models that use large datasets. How do you control for as much bias as possible? How can you quantify uncertainty? Read more about how your eBird data are having impact here.
