online_cvxNDL

This is the github repository of our Online Convex Network Dictionary Leanring algorithm (online cvxNDL).

Packages

The following packages are needed to run the code

python=3.8
pandas
matplotlib
ipdb
tqdm
scikit-learn
k-means-constrained
cvxpy
networkx
tensorly
psutil

To run the optimization algorithm

We provide synthetic data generated by the Stochastic Block Model (SBM) for quick verfication. For the full ChIA-Drop dataset, please refer to this link.

To run the example for the synthetic dataset

source run_example.sh

Note that we separate the MCMC sampling procedure from the iterative optimization procedure to improve the overall efficiency. The MCMC sampling procedure can be found in the folder sampling.

To view the results in Jupyter notebook

Please go to the folder jupyter_notebook and select the corresponding notebooks for detailed results.
