scikit-uplift
===============

**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.

Read more about uplift modeling problem in `User Guide `__.

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.

Installation
-------------

**Install** the package by the following command from PyPI:

.. code-block:: bash

pip install scikit-uplift

Or install from source:

.. code-block:: bash

git clone https://github.com/maks-sh/scikit-uplift.git
cd scikit-uplift
python setup.py install

Documentation
--------------

The full documentation is available at `uplift-modeling.com`_.

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

.. code-block:: bash

cd docs
pip install -r requirements.txt
make html

And if you now point your browser to ``_build/html/index.html``, you should see a documentation site.

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 `__.

.. code-block:: python

# 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
slearner.fit(
X=X_tr,
y=y_tr,
treatment=trmnt_tr,
)

# predict uplift
uplift_slearner = slearner.predict(X_val)

**Evaluate your uplift model**

Uplift model evaluation metrics are available in `sklift.metrics `__.

.. code-block:: python

# 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,
treatment=trmnt_val,
strategy='overall', k=0.3)

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

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

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

**Vizualize the results**

Visualize performance metrics with `sklift.viz `__.

.. code-block:: python

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

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

plot_qini_curve(
y_test, uplift_slearner, trmnt_test,
perfect=True, name='Slearner', ax=ax
);

plot_qini_curve(
y_test, uplift_revert, trmnt_test,
perfect=False, name='Revert label', ax=ax
);
