Kaggle is an online platform created by Anthony Goldbloom in 2010 and now owned by Google. It is the world’s largest data science and machine-learning community, with over 19 million users from 194 countries. The site hosts thousands of public datasets that can be copied and executed in browser-based Jupyter notebooks, and it offers 16,000+ competitions in which participants build models to solve real-world problems posted by companies, governments, and researchers. Competitions award cash prizes, ranking points, and medals that appear on public profiles. Kaggle also provides 1,000+ free micro-courses and curated learning paths covering Python, pandas, computer vision, NLP, and Generative AI; each course contains short video lectures, code notebooks, and mastery-based quizzes. Users can publish notebooks that receive upvotes, join discussion forums, and follow granular career tags. The platform’s Models section lets developers share and download pretrained models, while Datasets supports version-controlled repositories with rich metadata. Overall, Kaggle combines open data, cloud compute, gamified learning, and a meritocratic leaderboard to create a collaborative ecosystem for beginners and experts alike.
