### **What's special about this challenge?** ⭐
As you would have noticed the challenge name is "Data Purchasing Challenge". Wonder why? 😉
This challenge features online evaluation in which your submissions don't only train & predict online. BUT go through **purchase phase** as well.
**What is a Purchase Phase?** 🤔
This challenge has subset of the dataset which is unlabelled. During the purchase phase, your model is provided with a fixed budget. Your model can use that budget and ask images to be labelled using `purchase_label` function.
In this sense, participants have to make a data purchasing decision.
