Thank you for bringing this to our attention.
We have removed the identified duplicate data from both the training dataset and the ground truth CSV file to eliminate any risk of data leakage.
In light of recent concerns regarding data/ground truth agreements, we have also decided to extend the validation phase by one week. This will ensure all participants have ample time to validate their models under consistent and fair conditions.
If you encounter any further anomalies, please don’t hesitate to reach out. Your feedback helps strengthen the quality of this challenge.
Best regards,
The LISA 2025 Challenge Organizers
