A team led by George Dahl, a graduate student from University of Toronto won the Kaggle’s Merck Drug Discovery Challenge. Machine Learning algorithm that they have used to won the challenge is using an ensemble of supervised learning algorithms. But the most important part of this algorithm is the deep neural network that they have used with a recent training trick called droputs .
