Motif and Hypergraph Correlation Clustering

no code implementations5 Nov 2018 Pan Li, Gregory J. Puleo, Olgica Milenkovic

Our contributions are as follows: We first introduce several variants of motif correlation clustering and then show that these clustering problems are NP-hard.

A new correlation clustering method for cancer mutation analysis

no code implementations25 Jan 2016 Jack P. Hou, Amin Emad, Gregory J. Puleo, Jian Ma, Olgica Milenkovic

To test $C^3$, we performed a detailed analysis on TCGA breast cancer and glioblastoma data and showed that our algorithm outperforms the state-of-the-art CoMEt method in terms of discovering mutually exclusive gene modules and identifying driver genes.

Correlation Clustering and Biclustering with Locally Bounded Errors

no code implementations26 Jun 2015 Gregory J. Puleo, Olgica Milenkovic

We consider a generalized version of the correlation clustering problem, defined as follows.

Correlation Clustering with Constrained Cluster Sizes and Extended Weights Bounds

no code implementations3 Nov 2014 Gregory J. Puleo, Olgica Milenkovic

We consider the problem of correlation clustering on graphs with constraints on both the cluster sizes and the positive and negative weights of edges.
