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.
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.
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>
_.
.. 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)
