We are now discussing about this matter and the decision is not easy to take.

Sharing data from 2018 competition would be highly appreciated.<br class="">However our question is a little bit wider. The data shared from 2017 and before editions are so called training and evaluation data. Training data contain Wi-Fi and other sensor readings plus true locations. That’s fine. The evaluation data don’t contain locations because the location should be estimated by the competing algorithm. That’s obvious. Our question was, could you please share the true locations for the evaluation data for 2018 and before editions?.
