What is Kaggle?
Kaggle is a free online data science and machine learning platform owned by Google. It hosts ML competitions with prize money, a large library of public datasets and pre-trained models, browser-based Python and R notebooks with free CPU, GPU and TPU compute, short Kaggle Learn courses, and benchmarks. It has more than 15 million users.
Learning machine learning is hard without real data, compute and feedback. Kaggle bundles all three: download a dataset, train a model in a hosted notebook on a free GPU, and submit to a competition leaderboard to see how you rank against others. Public notebooks and discussions show how top solutions work, and a progression system from Novice to Grandmaster rewards contributions, which many data scientists use as a public portfolio.
