Extracting symbolic activation functions

[WJiangH]

Hi,

I have a question about extracting symbolic activation functions after fixed symbolic for each activation functions in KAN models. The tutorial shows how to get the activation function values and I am wondering is there built-in functions for output the symbolic formula for each activation function.

Thanks, JJ
