Installation

Binaries

wildboar is available through pip and can be installed with:

pip install wildboar

Universal binaries are compiled for Python 3.8, 3.9, 3.10 and 3.11 running on GNU/Linux, Windows and macOS.

Compilation

If you already have a working installation of numpy, scikit-learn, scipy and cython, compiling and installing wildboar is as simple as:

pip install .

To install the requirements, use:

pip install -r requirements.txt

For complete instructions see the documentation

Usage

from wildboar.ensemble import ShapeletForestClassifier
from wildboar.datasets import load_dataset
x_train, x_test, y_train, y_test = load_dataset("GunPoint", merge_train_test=False)
c = ShapeletForestClassifier()
c.fit(x_train, y_train)
c.score(x_test, y_test)

The User guide includes more detailed usage instructions.
