TargetMinMaxScaler

Applies min-max scaling to the target.

Parameters

• regressor

  Type → base.Regressor

  Regression model to wrap.

Examples

from river import datasets
from river import evaluate
from river import linear_model
from river import metrics
from river import preprocessing

dataset = datasets.TrumpApproval()
model = (
    preprocessing.StandardScaler() |
    preprocessing.TargetMinMaxScaler(
        regressor=linear_model.LinearRegression(intercept_lr=0.15)
    )
)
metric = metrics.MSE()

evaluate.progressive_val_score(dataset, model, metric)

MSE: 2.018905
