Contests are usually applied in the academic environment to simulate real professional situations that require from the participants a more pro-active attitude than the one shown in conventional coursework.

We build a tractable structural model to study the dynamic participation incentives in online competitions. We estimate the model using publicly available data from 17 prediction contests hosted by the website Kaggle.com. We study how participants’ incentives are shaped by the contest design in a series of counterfactual exercises. Specifically, we study how disclosing a leaderboard, awarding d...

In this work, we describe the main features of IFS-CoCo, a coevolutionary method performing instance and feature selection for nearest neighbor classifiers. The coevolutionary model and several related background topics are revised, in order to present the method to the ICPR’10 contest “Classifier domains of competence: The Landscape contest”. The results obtained show that our proposal is a ve...
