Challenge Rules



1. Competition Description

The ZEW Data Purchasing Challenge 2022 is a competition on data valuation. In this competition, participants face data purchasing challenges in the context of an multi-label image classification task in a quality control setting. The images consist of synthetically generated images of painted metal sheets. A classifier is meant to predict whether the metal sheets have production damages and if so which ones. Participants have access to a set of images, a subset of which are labeled with respect to production damages. They have to decide which of the unlabeled images labels should be labeled.

2. Sponsors

The Competition is organized by AIcrowd SA, referred to as "Organizers'' collectively from here on. Third parties may provide sponsorship to cover running costs, prizes, and compute grants. These third parties will be known as "Sponsors".
