[P] I would like to add a feature to my model that contains data that is in a tree like structure. • r/MachineLearning

This is an interesting problem I have not had before to do with a project I am working on. So far the data structures of my features have been basic discrete or continuous numbers or categories. Now I find myself needing to add a feature that has a treelike data structure. Googling to try and find out about how to input a tree like data structure as a feature to my model just has things come up to do with a decision tree model type, but not answering my question. Does any have any experience/insight on how to use tree like data as a feature to their existing model that already has categorical and continous numerical features?
