A novel link prediction algorithm for reconstructing protein–protein interaction networks by topological similarity

TL;DR: A novel algorithm to reduce the noise present in PPI networks and find that the edges in the reconstructed network have higher biological relevance than in the original network, assessed by multiple types of information.

Tag-aware recommender systems: a state-of-the-art survey

TL;DR: This article summarizes recent progress about tag-aware recommender systems, emphasizing on the contributions from three mainstream perspectives and approaches: network-based methods, tensor- based methods, and the topic-based Methods.

Assessing interbank contagion using simulated networks

TL;DR: A new approach to randomly generate interbank networks while overcoming shortcomings in the availability of bank-by-bank bilateral exposures is presented and a simplified measure—a so-called Systemic Probability Index—that also captures the likelihood of contagion from the failure of a given bank to honour its interbank payment obligations is proposed.

Generating Synthetic Decentralized Social Graphs with Local Differential Privacy

TL;DR: This paper proposes LDPGen, a novel multi-phase technique that incrementally clusters users based on their connections to different partitions of the whole population, and derives optimal parameters in this process to cluster structurally-similar users together.

Predicting semantically linkable knowledge in developer online forums via convolutional neural network

TL;DR: This paper forms the problem of predicting semantically linkable knowledge units as a multiclass classification problem, and solves the problem using deep learning techniques, and adopts neural language model (word embeddings) and convolutional neural network (CNN) to capture word- and document-level semantics of knowledge units.

Collective dynamics of small-world networks

TL;DR: Simple models of networks that can be tuned through this middle ground: regular networks ‘rewired’ to introduce increasing amounts of disorder are explored, finding that these systems can be highly clustered, like regular lattices, yet have small characteristic path lengths, like random graphs.

Equation of state calculations by fast computing machines

TL;DR: In this article, a modified Monte Carlo integration over configuration space is used to investigate the properties of a two-dimensional rigid-sphere system with a set of interacting individual molecules, and the results are compared to free volume equations of state and a four-term virial coefficient expansion.

Emergence of Scaling in Random Networks

TL;DR: A model based on these two ingredients reproduces the observed stationary scale-free distributions, which indicates that the development of large networks is governed by robust self-organizing phenomena that go beyond the particulars of the individual systems.

The meaning and use of the area under a receiver operating characteristic (ROC) curve.

James A. Hanley, +1 more
- 01 Apr 1982 - 
TL;DR: A representation and interpretation of the area under a receiver operating characteristic (ROC) curve obtained by the "rating" method, or by mathematical predictions based on patient characteristics, is presented and it is shown that in such a setting the area represents the probability that a randomly chosen diseased subject is (correctly) rated or ranked with greater suspicion than a random chosen non-diseased subject.

Statistical mechanics of complex networks

TL;DR: In this paper, a simple model based on the power-law degree distribution of real networks was proposed, which was able to reproduce the power law degree distribution in real networks and to capture the evolution of networks, not just their static topology.
