Kaggle is a website for data science and machine learning where people enter competitions, share and download datasets, and run notebooks.
In plain words
Kaggle brings three things together: competitions, where people work on the same data problem; datasets that anyone can search and download; and notebooks and scripts, which Kaggle calls kernels. An official command-line tool lets you download data and take part in competitions from your own computer.
A quick example
Imagine you want to practise predicting house prices. You find a public dataset on Kaggle, download it with the command-line tool, build a model in a notebook, and compare your approach with notebooks other people shared.
Where you'll meet it
- Learning and practising machine learning.
- Finding public datasets.
