Rules

For your submitted solution to the HYPERVIEW2 challenge to be eligible, the following rules need to be adhered to:

Participants

Participants from all over the world can participate in the challenge. However, please refer to the Prizes section to verify whether you are eligible to receive a prize in your current location. You must be of legal age in your jurisdiction to participate.

Teams

Each participating team is required to appoint a team leader. This team leader will be the main contact point between the organisers and the team.

Any participant may only be competing in and be part of one participating team during the HYPERVIEW2 Challenge. Teams are not allowed to create a second or duplicated entity.

To ensure fairness and transparency, we kindly ask that participants from the same public organisation or private company form a single team for the challenge. If multiple teams from the same entity appear to be working together, the Φ-Lab Challenges organising team may require them to merge into one team. This helps avoid any unfair advantage and ensures a level playing field for all participants.

If you plan to join the challenge with colleagues from your workplace or academic institution, please coordinate to register as one unified team per entity.

Note: Due to the size of the institutions and potential challenge partners, university students are exempt from this rule.

The Φ-Lab Challenges organising team may request you to delete any duplicate applications or submissions.

Creating and submitting a solution

For the challenge, you have access to the training and test datasets and a range of tools in the form of a Jupyter Notebook (Starter Pack). All usable data is hosted on the EOTDL. No other datasets might be used for the development of your solution. However, pre-trained models are allowed.

Participants are allowed to upload their solutions every 12 hours (to avoid overload and unfair behaviours). The final submission of your solution must be uploaded latest by 14 September 2025 (16:00 CEST / 4 PM CEST). Each valid submission must consist of the predictions of all soil parameters, over all test examples. For more details on the submission format, see the Jupyter notebook (Starter Pack).

Challenge evaluation

The scoring of submitted solutions is performed directly by the platform. A public leaderboard lets you see and compare your current points in relation to other teams’ submissions. A private leaderboard will be disclosed at the end of the competition, to be used for the final ranking. Please note that, if the solution turns out to be not reproducible, or if any concerns about its validity arises, the organisers reserve the right to contact the team leader of the corresponding team to resolve such issues. If the issues cannot be resolved, the team will not be eligible to receive prizes.

The final evaluation is based on the quantitative evaluation based on the HYPERVIEW Score and the quality of the XAI analysis developed by the participants.

Solution presentation

The winners of the Φ-Lab HYPERVIEW2 Challenge will be publicly awarded during the EASi Workshop held at the 28th European Conference on Artificial Intelligence (ECAI) on 25/26 October 2025 in Bologna, Italy. To offer the winners the chance to present their great solutions and to ensure full transparency of the products, the winning teams are expected to present their respective solutions in a pitch-style manner of ca. 10 minutes per team with the use of a short pitch-deck (for example in the form of a PowerPoint presentation).
