RxSci operators for Scikit River.
Evaluate and train a Hoeffding Tree Classifier from a stream of events:
import rx
import rxsci_river as rsr
from river import synth
from river.tree import HoeffdingTreeClassifier
gen = synth.Agrawal(classification_function=0, seed=42)
rx.from_(gen.take(1000)).pipe(
rsr.evaluate.prequential(
model=HoeffdingTreeClassifier(
grace_period=100,
split_confidence=1e-5,
nominal_attributes=['elevel', 'car', 'zipcode'],
),
pretrain_size=100),
).subscribe(
on_next=print,
)See the Maki Nage documentation for more information.
RxSci River is available on PyPi and can be installed with pip:
