======================
Fast Multicore HDBSCAN
======================
Ahe ``fast_hdbscan`` library provides a simple implementation of the HDBSCAN clustering algorithm designed specifically
for high performance on multicore machine with low dimensional data. The algorithm runs in parallel and can make
effective use of as many cores as you wish to throw at a problem. It is thus ideal for large SMP systems, and even
modern multicore laptops.
This library provides a
re-implementation of a subset of the HDBSCAN algorithm that is compatible with the
`hdbscan <https://github.com/scikit-learn-contrib/hdbscan>`_ library for data that is Euclidean and
low dimensional. The primary advantages of this library over the standard ``hdbscan`` library are:
* this library can easily use all available cores to speed up computation;
* this library has much faster implementations of tree condensing and cluster extraction;
* this library is much simpler and more approachable for extending or using components from;
* this library is built on numba and has less issues with binaries and compilation.
This library does not support all the features and input formats available in the hdbscan library.
-----------
Basic Usage
-----------
The ``fast_hdbscan`` library follows the ``hdbscan`` library in using the sklearn API. You can use the ``fast_hdbscan``
class ``HDBSCAN`` exactly as you wuld that of the ``hdbscan`` library with the caveat that ``fast_hdbscan`` only
supports a subset of the parameters and options of ``hdbscan``. Nonetheless, if you have low-dimensional
Euclidean data (e.g. the output of UMAP), you can use this library as a straightforward drop in replacement for
``hdbscan``:
.. code:: python
import fast_hdbscan
from sklearn.datasets import make_blobs
data, _ = make_blobs(1000)
clusterer = fast_hdbscan.HDBSCAN(min_cluster_size=10)
cluster_labels = clusterer.fit_predict(data)
------------
Installation
------------
fast_hdbscan requires:
* numba
* numpy
* scikit-learn
fast_hdbscan can be installed via pip:
.. code:: bash
pip install fast-hdbscan
To manually install this package:
.. code:: bash
wget https://github.com/TutteInstitute/fast_hdbscan/archive/main.zip
unzip main.zip
rm main.zip
cd fast_hdbscan-main
python setup.py install
