boostsrl 0.4.0

Getting Started

Prerequisites:

• Java 1.8

• Python (3.6, 3.7)

Installation

pip install boostsrl

Basic Usage

The general setup should be similar to scikit-learn. But there are a few extra requirements in terms of setting background knowledge and formatting the data.

A minimal working example (using the Toy-Cancer data set imported with ‘example_data’) is:

>>> from boostsrl.rdn import RDN
>>> from boostsrl import Background
>>> from boostsrl import example_data
>>> bk = Background(
...     modes=example_data.train.modes,
... )
>>> clf = RDN(
...     background=bk,
...     target='cancer',
...     max_tree_depth=2,
...     node_size=1,
... )
>>> clf.fit(example_data.train)
>>> clf.predict_proba(example_data.test)
array([0.88079619, 0.88079619, 0.88079619, 0.3075821 , 0.3075821 ])
>>> clf.classes_
array([1., 1., 1., 0., 0.])

example_data.train and example_data.test are each boostsrl.Database objects, so this hides some of the complexity behind the scenes.

This example abstracts away some complexity in exchange for compactness. For more thorough examples, see the ‘docs/examples/’ directory.
