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. [1]
Kaggle was founded by Anthony Goldbloom and Ben Hamner in April 2010. [2] Jeremy Howard, one of the first Kaggle users, joined in November 2010 and served as the President and Chief Scientist. [3] Also on the team was Nicholas Gruen serving as the founding chair. [4] In 2011, the company raised $12.5 million and Max Levchin became the chairman. [5] On 8 March 2017, Fei-Fei Li, Chief Scientist at Google, announced that Google was acquiring Kaggle. [6]
In June 2017, Kaggle surpassed 1 million registered users, and as of October 2023, it has over 15 million users in 194 countries. [7] [8] [9]
In 2022, founders Goldbloom and Hamner stepped down from their positions and D. Sculley became the CEO. [10]
In February 2023, Kaggle introduced Models which allowed users to discover and use pre-trained models through deep integrations with the rest of Kaggle’s platform. [11]
Many machine-learning competitions have been run on Kaggle since the company was founded. Notable competitions include gesture recognition for Microsoft Kinect, [12] making a football AI for Manchester City, coding a trading algorithm for Two Sigma Investments, [13] and improving the search for the Higgs boson at CERN. [14]
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, via 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. After the deadline passes, the competition host pays the prize money in exchange for "a worldwide, perpetual, irrevocable and royalty-free license [...] to use the winning Entry", i.e. the algorithm, software and related intellectual property developed, which is "non-exclusive unless otherwise specified". [15]
Alongside its public competitions, Kaggle also offers private competitions, which are limited to Kaggle's top participants. Kaggle offers a free tool for data science teachers to run academic machine-learning competitions. [16] Kaggle also hosts recruiting competitions in which data scientists compete for a chance to interview at leading data science companies like Facebook, Winton Capital, and Walmart.
Kaggle's competitions have resulted in successful projects such as furthering HIV research, [17] chess ratings [18] and traffic forecasting. [19] Geoffrey Hinton and George Dahl used deep neural networks to win a competition hosted by Merck.[ citation needed ] Vlad Mnih (one of Hinton's students) used deep neural networks to win a competition hosted by Adzuna.[ citation needed ] This resulted in the technique being taken up by others in the Kaggle community. Tianqi Chen from the University of Washington also used Kaggle to show the power of XGBoost, which has since replaced Random Forest as one of the main methods used to win Kaggle competitions.[ citation needed ]
Several academic papers have been published on the basis of findings made in Kaggle competitions. [20] A contributor to this is the live leaderboard, which encourages participants to continue innovating beyond existing best practices. [21] The winning methods are frequently written on the Kaggle Winner's Blog.

Kaggle has implemented a progression system to recognize and reward users based on their contributions and achievements within the platform. This system consists of five tiers: Novice, Contributor, Expert, Master, and Grandmaster. Each tier is achieved by meeting specific criteria in competitions, datasets, kernels (code-sharing), and discussions. [22]
The highest and most prestigious tier, Kaggle Grandmaster, is awarded to users who demonstrate exceptional skills in data science and machine learning. Achieving this status is extremely challenging. As of April 4, 2023, out of 12 million Kaggle users, only 2,331 (about 1 out of every 5500 users) have reached the Master level.
Among these Masters, only 472 (approximately 1 out of every 5 Masters) have achieved the coveted Kaggle Grandmaster status. [23]
The other tiers in the progression system include:
The progression system serves to motivate users to continuously improve their skills and contribute to the Kaggle community.
Maksymilian Rafailovych "Max" Levchin is a Ukrainian-American software engineer and businessman. In 1998, he co-founded the company that eventually became PayPal. Levchin made contributions to PayPal's anti-fraud efforts and was the co-creator of the Gausebeck-Levchin test, one of the first commercial implementations of a CAPTCHA challenge response human test.

There are a number of competitions and prizes to promote research in artificial intelligence.
Cloud computing is the on-demand availability of computer system resources, especially data storage and computing power, without direct active management by the user. Large clouds often have functions distributed over multiple locations, each of which is a data center. Cloud computing relies on sharing of resources to achieve coherence and typically uses a pay-as-you-go model, which can help in reducing capital expenses but may also lead to unexpected operating expenses for users.
Figure Eight was a human-in-the-loop machine learning and artificial intelligence company based in San Francisco.
Andrew Yan-Tak Ng is a British-American computer scientist and technology entrepreneur focusing on machine learning and artificial intelligence (AI). Ng was a cofounder and head of Google Brain and was the former Chief Scientist at Baidu, building the company's Artificial Intelligence Group into a team of several thousand people.
Anthony John Goldbloom is the founder and former CEO of Kaggle, a data science competition platform which has used predictive modelling competitions to solve data problems for companies, such as NASA, Wikipedia, Ford and Deloitte. Kaggle has operated across a range of fields, including mapping dark matter and HIV/AIDS research. Kaggle has received considerable media attention following news that it had received $11.25 million in Series A funding from a round led by Khosla Ventures and Index Ventures.

Learning Engineering is the systematic application of evidence-based principles and methods from educational technology and the learning sciences to create engaging and effective learning experiences, support the difficulties and challenges of learners as they learn, and come to better understand learners and learning. It emphasizes the use of a human-centered design approach in conjunction with analyses of rich data sets to iteratively develop and improve those designs to address specific learning needs, opportunities, and problems, often with the help of technology. Working with subject-matter and other experts, the Learning Engineer deftly combines knowledge, tools, and techniques from a variety of technical, pedagogical, empirical, and design-based disciplines to create effective and engaging learning experiences and environments and to evaluate the resulting outcomes. While doing so, the Learning Engineer strives to generate processes and theories that afford generalization of best practices, along with new tools and infrastructures that empower others to create their own learning designs based on those best practices.
