Network Enhancement: a general method to denoise weighted biological networks

Project website: http://snap.stanford.edu/ne.

Overview

Networks are abundant in many areas of biology. These networks often entail non-trivial topological features and patterns critical to understanding interactions within the natural system. However, networks observed in real-world are typically noisy. The presence of high levels of noise can hamper discovery of structures and dynamics present in the network.

We propose Network Enhancement (NE), a novel method for improving the signal-to-noise ratio of a symmetric networks and thereby facilitating the downstream network analysis. NE leverages the transitive edges of a network by exploiting local structures to strengthen the signal within clusters and weaken the signal between clusters. At the same time NE also alleviates the corrupted links in the network by imposing a normalization that removes weak edges by enforcing sparsity. NE is supported by theoretical justifications for its convergence and performance in improving community detection outcomes.

The method provides theoretical guarantees as well as excellent empirical performance on many biological problems. The approach can be incorporated into any weighted network analysis pipeline and can lead to improved downstream analysis.
