It only makes sense train a tree on a subset as part of an ensembl method,
and in that case you can train a set of trees by training each one on a
subset of the data (be sure to randomly choose the subset though).
It's true that ensembl methods like RandomForest don't have partial_fit,
but you could still train the model on subsets and combine them.
