Are training instances stored or purged post training?

[royr2]

Hi!
Came across this library and played around with it a little bit - love how easy it is to get started with it. I am trying to figure out if any training instances are stored for future use somewhere within the model object? For my specific use case, I cannot store any data once it has been used to incrementally train the model (for legal reasons).

Thanks!

Hi @royr2. Most of River's learning models only keep data statistics. There are, however, cases where a window of recent examples is kept. This includes, for instance, k Nearest Neighbors Classifier/Regressor.

Appreciate the response @smastelini!
