<p>How do you answer a question like, “Is the particularly round robin that visits my bird feeder huge or just fluffy?” This talk documents Hugh's attempt to answer this question by building a smart bird feeder that tracks the weight of visiting birds, which, in combination with a custom computer vision model and a night-vision webcam, helped him build a dataset of all the visitors to his bird feeder and how that led to the creation of a large-scale data pipeline for citizen science ornithology.</p> <p>In this talk, Hugh will explore working with sensor data, data streaming, multimodal data analysis at scale, and the answer to the titular question, “How heavy is this robin?”</p>
