# Locality Preserving Projections in Python

This is a Python implementation of Locality Preserving Projections (LPP), compatible with scikit-learn.

## Installation and Use

This package is pure Python, and depends only on [numpy](http://numpy.org/), [scipy](http://scipy.org/), and [scikit-learn](http://scikit-learn.org/).

The released version can be installed via pip:

    $ pip install lpproj

A basic example of its use can be found in [Example.ipynb](Example.ipynb); the library follows scikit-learn's patterns for ``fit()``, ``transform()``, and ``fit_transform()``. The simplest example for a feature matrix ``X``:

```python

from lpproj import LocalityPreservingProjection 

lpp = LocalityPreservingProjection(n_components=2)

X_2D = lpp.fit_transform(X)

```

## More Information

For information on the LPP algorithm, see the paper, [Locality Preserving Projections (pdf)](http://papers.nips.cc/paper/2359-locality-preserving-projections.pdf).
