SAN FRANCISCO--(BUSINESS WIRE)--In honor of its second anniversary, Kaggle, the premier platform for predictive modeling competitions, is releasing its first-ever global leaderboard of data scientists. Since its founding in April 2010, the Kaggle community has grown to include more than 33,000 data scientists who compete to develop the best solutions to some of the toughest predictive challenges. Each competition posted on the Kaggle site features a real-time public leaderboard, which serves to motivate the competitors to improve their solutions as much as — and sometimes more than — the cash prizes awarded to winners. As the top competitors leapfrog each other in the rankings, they push one another towards even greater accuracy in their algorithms, leading them to achieve breakthroughs across many industries, from forecasting insurance claims to furthering HIV research.
Below are details about each of the top ten data scientists active on Kaggle.
1. Alexander D’yakonov
An academic in the Faculty of Computational Mathematics and Cybernetics department at Moscow State University, Alexander modestly describes his favorite problem-solving technique as “luck.” Despite this, the 33-year-old Russian has earned a reputation for using methods known for their theoretical rigor and elegant simplicity. This helped him to win the dunnhumby Shopper Challenge, which asked competitors to predict the amount and timing of supermarket shoppers’ next spends.
2. Sergey Yurgenson
With a Ph.D. in physics from Leningrad (now St. Petersburg) State University and his current position as a research associate in neurobiology at Harvard Medical School, Sergey Yurgenson has combined both of his areas of expertise to develop computational algorithms inspired by biology. Favoring neural networks, a type of learning algorithm modeled on how brain cells work, the 50-year-old’s best finish came in NASA’s Mapping Dark Matter competition. To tackle the task of analyzing images of galaxies, Yurgenson combined several different kinds of neural networks.
3. Vivek Sharma
With a master’s degree in computer science from the University of Virginia, 32-year-old Vivek Sharma is now based in Delhi, where he has become one of Kaggle’s most consistent performers. His recent best results were in the credit scoring competition Give Me Some Credit and in the Algorithmic Trading Challenge.
4. Jose H. Solorzano
Jose H. Solorzano is a 42-year-old software engineer based in Quito, Ecuador. He has previously worked on open source projects, including the robotics software behind Lego Mindstorms. Solorzano’s software has been used to design a space junk collection system constructed entirely out of Lego pieces and put to test in orbit. His most notable Kaggle success was when he won Don’t Overfit!, a competition aimed at improving predictive algorithm strategies that attracted the attention of many of Kaggle’s most enthusiastic users.
5. Xavier Conort
Xavier Conort is a French actuary whose adventures have taken him to Brazil, China, and Singapore, where he is currently based. He is the founder of Gear Analytics, a consulting firm that helps insurance firms and other companies use predictive modeling. The 39-year-old’s affinity for American car culture helped him win the hotly contested Don’t Get Kicked! competition, which asked Kaggle contestants to develop a mathematical model that can work out which used cars are most likely to be bad buys, or “kicks.”
6. Tim Salimans
Tim Salimans is a 26-year-old Ph.D. candidate in econometrics at Erasmus University Rotterdam in the Netherlands. He triumphed in the World Chess Federation (FIDE)-sponsored Deloitte/FIDE Chess Rating Challenge on Kaggle. The task was to predict the outcomes of chess games, thus developing a better ratings system. Saliman’s trick was to create a modified version of the method used by Microsoft to rate Xbox players, a variant that ended up being better than standard ranking algorithm.
7. Vladimir Nikulin
Vladimir Nikulin has a Ph.D. in mathematical statistics from Moscow State University and has worked as an academic in Russia and Australia. A veteran of data mining competitions, the 52-year-old sees them as an essential part of the research process since they help researchers identify real from illusory progress in their methods. His best Kaggle finish was third place in the used car defect prediction challenge ‘Don’t Get Kicked!’.
8. David J. Slate
David J. Slate holds more than half a century’s experience in programming. He was building operating systems and cracking chess programs decades ago, winning the World Computer Chess Championship in 1977. A former academic at Northwestern University in Evanston, Ill., today he spends his retirement entering Kaggle competitions under the moniker “Old Dogs with New Tricks.” His best performance on Kaggle came when he won the R Package Recommendation Engine competition for recommending software packages to users in the programming language R.
9. Yannis Sismanis
Yannis Sismanis is a researcher at IBM’s Almaden Research Center in San Jose, Calif., where he works on data intensive analytics. Originally from Greece, his background is in electrical engineering and computer science. Sismanis won the first of two Kaggle competitions aimed at improving chess ratings systems, called Chess ratings - Elo versus the Rest of the World.
10. Jason Tigg
Jason Tigg grew up on the Isle of Thanet in southeast England and goes by the alias “PlanetThanet” on Kaggle. At age 14, he used assembly language to build a program that could play Othello. The 43-year-old now holds a Ph.D. in elementary particle physics from Oxford and is based in London, where he works in the finance sector. Tigg’s performances on Kaggle have been outstanding, notably in the Photo Quality Prediction competition and the Claim Prediction Challenge.
Kaggle is the global leader in running predictive modeling competitions. The company has run approximately 100 competitions with major enterprise, government, and academic customers, including Allstate Insurance, Boehringer Ingelheim, Dunnhumby, Ford, Heritage Health, Microsoft, NASA, Stanford, and Wikipedia. Over 33,000 data scientists worldwide have contributed to competitions that tackled the toughest predictive problems in the marketing, life sciences, insurance, financial services, travel, and science industries. Kaggle’s investors include Index Ventures and Khosla Ventures. It was founded in 2010 and is based in San Francisco, Calif.
