How did you choose loss weights in the 2D steady and time dependent example?

Hi everyone,

Thank you so much for sharing your research.

I just wanted to know how you chose the loss weight values in the 2D examples?

Best regards,

Hello,

We started by setting the weights of the PDE initially to 1 / (OOM of E / OOM of u). The data losses were kept at 1 for simplicity. This was an initial start point, and we did some manual tuning to improve predictions by lowering the overall loss.
