Using operator learning if dimension of input function is more than 1

[sibyjackgrove]

The examples given for DeepOnet use data sets with only one input function. What should I modify to use more than one input function? Also is there an example for MIOnet?

Thanks, I tried this out using the implementation in https://github.com/lu-group/mionet/blob/main/training/MIONet_training.py. However, MIONetCartesianProd can only take two input functions. Is there an implementation for more than 2 input functions?

You can modify the code. It is straightforward.
