And Vlad Mnih (one of Hinton's students) used deep neural networks to win a competition hosted by Adzuna. This helped show the power of deep neural networks and 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 taken over from Random Forest as one of the main methods used to win Kaggle competitions.
