A New Stacking Method For Winning A Gold Medal In Zillow Prize Competition: The Triad Method
The Zillow Prize challenge on Kaggle was one of the most popular competitions with more than 4,000 participants. Our team at Prizmi were among the participants and won two medals. To win those competitions, we invented and implemented a novel approach to combine the predictions of several models. We are happy to announce that Leaner now supports this method. In this article, we introduce the Triad method and show how it can be done using Leaner without writing any code.
