About Kaggle
Kaggle is a community platform for data science and machine learning, with public datasets, hosted notebooks and competitions. It is one of the best known places for people to practise data work against real problems.
What it does
You can browse datasets shared by others, open a notebook that runs in your browser and study other people's solutions. Competitions invite teams to build models for a stated problem, and the leaderboard ranks entries. The site also hosts benchmarks and leaderboards that compare models and tools, and it has discussion forums and free courses for learning.
Key features
- Public datasets for analysis and modelling
- Hosted notebooks that run in the browser
- Machine learning competitions with prizes
- Benchmarks and leaderboards for comparing models
- Free courses and community discussions
Who it's for
Students, data scientists and machine learning engineers who want to build skills, share work or test ideas against a common problem. It is also used by researchers who need public data and benchmarks.
Pricing and good to know
Kaggle is free to use, including its notebooks and datasets. Competitions follow their own rules about data, team size and submissions, so read each one before entering. Some hosted resources have usage limits, and the community content varies in quality, so check how well a notebook is maintained before you rely on it.
