Open Multivariate Adaptive Regression

omar

WIP (name conflict see https://github.com/pypi/support/issues/6159)

omar (Open Multivariate Adaptive Regression) is a Python package for discovering localised, linear structure in complex, high-dimensional datasets. It implements a modernized version of the Multivariate Adaptive Regression Splines (MARS) algorithm with improved numerical efficiency, based on modern rank-one update strategies and optional Fortran acceleration.

Installation

From PyPI (coming soon)

pip install omar

From Source

See the Getting Started wiki page.

Quick Example

import numpy as np
from omar import OMAR

np.random.seed(0)

x = np.random.normal(2, 1, size=(1000, 3))
noise = np.random.normal(size=1000)
y = ((x[:, 0] + np.maximum(0, (x[:, 0] - 1)) +
      np.maximum(0, (x[:, 0] - 1)) * x[:, 1] +
      np.maximum(0, (x[:, 0] - 1)) * np.maximum(0, (x[:, 1] - 0.8))) +
     0.12 * noise)
model = OMAR(max_nbases=11)
model.find_bases(X, y)
print(model)
