I want to use the "label propagation algorithm" in APOC or other algorithm components to automatically calculate the labels of prediction nodes. Could you tell me how to realize this idea? Thank you.
Label propagation is not part of APOC; it's an algorithm available in our GDS library.
To access the library you can download it from our download center (it's a plug in that you can add to your database); for more details, our docs cover installation.
