.. _sec_tabularinterpretability:

Interpretable rule-based modeling
=================================


*Note*: This addition was made through collaboration with `the Yu
Group <https://www.stat.berkeley.edu/~yugroup/>`__ of Statistics and
EECS from UC Berkeley.

**Tip**: Prior to reading this tutorial, it is recommended to have a
basic understanding of the TabularPredictor API covered in
:ref:`sec_tabularquick`.

In this tutorial, we will explain how to automatically use interpretable
models powered by integration with `🔍 the imodels
package <https://github.com/csinva/imodels>`__. This allows for
automatically learning models based on rules which are extremely concise
and can be useful for (1) understanding data or (2) building a
transparent predictive model.

*Note*: ``imodels`` must be installed for this tutorial. You can ensure
``imodels`` is installed via ``pip install autogluon.tabular[imodels]``.
``imodels`` is not installed by default.

Begin by loading in data to predict. Note: interpretable rule-based
modeling is currently only supported for binary classification.

.. code:: python

    from autogluon.tabular import TabularDataset, TabularPredictor
    train_data = TabularDataset('https://autogluon.s3.amazonaws.com/datasets/Inc/train.csv')
    subsample_size = 500  # subsample subset of data for faster demo, try setting this to much larger values
    train_data = train_data.sample(n=subsample_size, random_state=0)
    train_data.head()

Now, we create a predictor and fit it to the data. By specifying
``presets='interpretable'``, we tell the predictor to fit only
interpretable models.

.. code:: python

    predictor = TabularPredictor(label='class')
    predictor.fit(train_data, presets='interpretable')
    predictor.leaderboard()

    	Note: For your binary classification, AutoGluon arbitrarily selected which label-value represents positive ( >50K) vs negative ( <=50K) class.

The rule-based models take slightly different forms (see below), but all
try to optimize predictive performance using as few rules as possible.
See the `imodels package <https://github.com/csinva/imodels>`__ for more
details.

Specifically, the interpretable preset fits different hyperparameter
configurations of 5 models types: 1. Greedy CART decision tree - returns
a tree learned via greedy optimization
(`Description <https://scikit-learn.org/stable/modules/tree.html#tree>`__,
`Paper <https://www.taylorfrancis.com/books/mono/10.1201/9781315139470/classification-regression-trees-leo-breiman-jerome-friedman-richard-olshen-charles-stone>`__)
2. Hierarchical Shrinkage tree - returns regularized version of CART
decision tree
(`Description <https://csinva.io/imodels/shrinkage.html>`__,
`Paper <https://arxiv.org/abs/2202.00858>`__) 3. Fast interpretable
greedy-tree sum - returns a *sum* of trees, which are greedily grown
simultaneously (`Description <https://csinva.io/imodels/figs.html>`__,
`Paper <https://arxiv.org/abs/2202.00858>`__) 4. RuleFit - returns a set
of weighted rules, which are learned by a sparse linear model on rules
extracted from decision trees
(`Description <https://christophm.github.io/interpretable-ml-book/rulefit.html>`__,
`Paper <https://arxiv.org/abs/0811.1679>`__) 5. Boosted rule set -
returns a set of rules, which are learned sequentially via AdaBoost
(`Description <https://scikit-learn.org/stable/modules/ensemble.html#adaboost>`__,
`Paper <https://www.sciencedirect.com/science/article/pii/S002200009791504X>`__)

In addition to the usual functions in ``TabularPredictor``, this
predictor fitted with interpretable models has some additional
functionality. For example, we can now inspect the complexity of the
fitted models (i.e. how many rules they contain).

We can also explicitly inspect the rules of the best-performing model.

.. code:: python

    predictor.print_interpretable_rules() # can optionally specify a model name or complexity threshold


.. parsed-literal::
    :class: output

    BoostedRulesClassifier(n_estimators=5, random_state=0)


In some cases, these rules are sufficient to accurately make
predictions. In other cases, they may just be used to gain a better
understanding of the data before proceeding with more black-box models.
