Hello Everyone,

I was reading a paper about DL for Symbolic Mathematics (https://arxiv.org/pdf/1912.01412.pdf). In Section C of the appendix, they have mentioned a few methods for generating mathematical equations:

I am not understanding what is the definition for K(e, n) in that section. Can someone help me in understanding it?
Any help would be appreciated :smile:

Thanks in advance.

PS: I am new to the community, please let me know if I had made a mistake.

Hey and welcome to the community. It’s seems like an interesting paper, but your question has nothing to do with Julia, so maybe “offtopic” would be a better category?

Thanks for the information. I have changed the topic accordingly. :smile:

You could write an email to the authors of the paper and ask them to clarify.

That’s a great idea! I’ll do that.

Reminds me of Group method of data handling - Wikipedia

A GMDH model with multiple inputs and one output is a subset of components of the base function (1):

Y(x_{1},ots ,x_{n})=a_{0}+um imits {{i=1}}^{m}a{i}f_{i}
where fi are elementary functions dependent on different sets of inputs, ai are coefficients and m is the number of the base function components.
