Fei-Fei Li is a Stanford computer scientist and the former chief scientist of artificial intelligence/machine learning at Google Cloud. When Li entered the field of AI in the 2000s, researchers were making slow progress, optimizing algorithms to incrementally improve outcomes. Li saw that the problem wasn’t the algorithm, but the size of the datasets being used. So she built a massive database of images called ImageNet. It was a huge breakthrough, and helped lead the emergence of modern AI.
