Sebastian Schelter is organizing the Bol.com Unwanted Product Detection Challenge 2021. In this challenge, the task is to automatically detect and classify wanted/unwanted products. This is a supervised learning task, where a training set is provided containing sample data of wanted/unwanted products. Based on this dataset, you should train a model to predict the labels for an unseen test dataset.
