Thank you for your work. I have two small questions regarding the dataset: <img width="1353" height="206" alt="Image" src="https://github.com/user-attachments/assets/da3366b9-ceb1-40bf-b199-dcede55e933b" /> 1. What do meta_result and meta_mask mean? <img width="474" height="470" alt="Image" src="https://github.com/user-attachments/assets/2e04ceb9-8523-41f0-80ca-34ea3f3b1e08" /> 2. Which part of the dataset does the score variable(paper Sec.2.2 , Eq.1) in the training data correspond to?
