scikit-uplift: uplift modeling in scikit-learn style in python


scikit-uplift (sklift) is an uplift modeling python package that provides fast sklearn-style models implementation, evaluation metrics and visualization tools.

Uplift modeling estimates a causal effect of treatment and uses it to effectively target customers that are most likely to respond to a marketing campaign.

Use cases for uplift modeling:

  • Target customers in the marketing campaign. Quite useful in promotion of some popular product where there is a big part of customers who make a target action by themself without any influence. By modeling uplift you can find customers who are likely to make the target action (for instance, install an app) only when treated (for instance, received a push).

  • Combine a churn model and an uplift model to offer some bonus to a group of customers who are likely to churn.

  • Select a tiny group of customers in the campaign where a price per customer is high.

Why sklift

  • Сomfortable and intuitive scikit-learn-like API;

  • More uplift metrics than you have ever seen in one place! Include brilliants like Area Under Uplift Curve (AUUC) or Area Under Qini Curve (Qini coefficient) with ideal cases;

  • Supporting any estimator compatible with scikit-learn (e.g. Xgboost, LightGBM, Catboost, etc.);

  • All approaches can be used in the sklearn.pipeline. See the example of usage on the Tutorials page;

  • Also metrics are compatible with the classes from sklearn.model_selection. See the example of usage on the Tutorials page;

  • Almost all implemented approaches solve classification and regression problems;

  • Nice and useful viz for analysing a performance model.


Install the package by the following command from PyPI:

pip install scikit-uplift

Or install from source:

git clone
cd scikit-uplift
python install


The full documentation is available at

Or you can build the documentation locally using Sphinx 1.4 or later:

cd docs
pip install -r requirements.txt
make html

Quick Start

See the RetailHero tutorial notebook (EN Open In Colab1, RU Open In Colab2) for details.

Train and predict uplift model

Use the intuitive python API to train uplift models with sklift.models.

# import approaches
from sklift.models import SoloModel, ClassTransformation
# import any estimator adheres to scikit-learn conventions.
from lightgbm import LGBMClassifier

# define models
estimator = LGBMClassifier(n_estimators=10)

# define metamodel
slearner = SoloModel(estimator=estimator)

# fit model

# predict uplift
uplift_slearner = slearner.predict(X_val)

Evaluate your uplift model

Uplift model evaluation metrics are available in sklift.metrics.

# import metrics to evaluate your model
from sklift.metrics import (
    uplift_at_k, uplift_auc_score, qini_auc_score, weighted_average_uplift

# Uplift@30%
uplift_at_k = uplift_at_k(y_true=y_val, uplift=uplift_slearner,
                          strategy='overall', k=0.3)

# Area Under Qini Curve
qini_coef = qini_auc_score(y_true=y_val, uplift=uplift_slearner,

# Area Under Uplift Curve
uplift_auc = uplift_auc_score(y_true=y_val, uplift=uplift_slearner,

# Weighted average uplift
wau = weighted_average_uplift(y_true=y_val, uplift=uplift_slearner,

Vizualize the results

Visualize performance metrics with sklift.viz.

from sklift.viz import plot_qini_curve
import matplotlib.pyplot as plt

fig, ax = plt.subplots(1, 1)
ax.set_title('Qini curves')

    y_test, uplift_slearner, trmnt_test,
    perfect=True, name='Slearner', ax=ax

    y_test, uplift_revert, trmnt_test,
    perfect=False, name='Revert label', ax=ax
