Kaggle

Kaggle is a data science competition platform and online community of data scientists and machine learning practitioners under Google LLC. Kaggle enables users to find and publish datasets, explore and build models in a web-based data science environment, work with other data scientists and machine learning engineers, and enter competitions to solve data science challenges. Kaggle was founded by Anthony Goldbloom and Ben Hamner in 2010 with Nicholas Gruen as the founding chair. Equity was raised in 2011 valuing the company at $25.2 million. On 8 March 2017, Google announced it was acquiring Kaggle. In June 2017, Kaggle surpassed 1 million registered users and, as of 2021, over 8 million. The users are based in 194 countries. In March 2017, Fei-Fei Li, Chief Scientist at Google, announced that Google was acquiring Kaggle during her keynote at Google Next. In 2022, founders Goldbloom and Hamner stepped down from their positions and D. Sculley became the CEO. In February 2023, Kaggle introduced Models which allows users to discover and use pre-trained models through deep integrations with the rest of Kaggle’s platform. Many machine-learning competitions have been run on Kaggle since the company was founded. Notable competitions include one improving gesture recognition for Microsoft Kinect, making a football AI for Manchester City, coding a trading algorithm for Two Sigma Investments, and improving the search for the Higgs boson at CERN. The competition host prepares the data and a description of the problem; the host may choose whether it's going to be rewarded with money or be unpaid. Participants experiment with different techniques and compete against each other to produce the best models. Work is shared publicly through Kaggle Kernels to achieve a better benchmark and to inspire new ideas. Submissions can be made through Kaggle Kernels, through manual upload or using the Kaggle API. For most competitions, submissions are scored immediately (based on their predictive accuracy relative to a hidden solution file) and summarized on a live leaderboard.
