Mellon is a non-parametric cell-state density estimator based on a
nearest-neighbors-distance distribution. It uses a sparse gaussian process
to produce a differntiable density function that can be evaluated out of sample.

Installation
============

To install Mellon using **pip** you can run:

.. code-block:: bash

   pip install mellon

or to install using **conda** you can run:

.. code-block:: bash

   conda install -c conda-forge mellon

or to install using **mamba** you can run:

.. code-block:: bash

   mamba install -c conda-forge mellon

Any of these calls should install Mellon and its dependencies within less than 1 minute.
If the dependency jax is not autimatically installed, please refer to https://github.com/google/jax.

Documentation
=============

Please read the
`documentation <https://mellon.readthedocs.io/en/latest/index.html>`_
or use this
`basic tutorial notebook <https://github.com/settylab/Mellon/blob/main/notebooks/basic_tutorial.ipynb>`_.


Basic Usage
===========

.. code-block:: python

    import mellon
    import numpy as np

    X = np.random.rand(100, 10)  # 10-dimensional state representation for 100 cells
    Y = np.random.rand(100, 10)  # arbitrary test data

    model = mellon.DensityEstimator()
    log_density_x = model.fit_predict(X)
    log_density_y = model.predict(Y)
