Note: This package supports Python 3.6 or newer.
This is a Python implementation of Continuous k-Nearest Neighbors(CkNN) proposed in the paper 'Consistent Manifold Representation for Topological Data Analysis' (https://arxiv.org/pdf/1606.02353.pdf)
This package only depends on numpy and
scipy. The package can be installed via pip:
$ pip install git+https://github.com/chlorochrule/cknn
X is a data matrix. A simple example is like:
from cknn import cknneighbors_graph
ckng = cknneighbors_graph(X, n_neighbors=5, delta=1.0)MIT
