Before revision:  This iterative approach has a closed-form solution at convergence with desirable performanceproperties. We demonstrate the effectiveness of NE in denoising biological networks for several challenging yet important problems. Our experiments show that NE improves gene function prediction by denoising interaction networks from 22 human tissues.
After revision:  This iterative approach has a closed-form solution that increases spectral eigengap of the input network. As a result, NE removes weak edges, enhances real connections, and leads to better downstream performance. Experiments show that NE improves gene function prediction by denoising interaction networks from 22 human tissues.
