Ranking in evolving complex networks

TL;DR: The aim of this review is to survey the existing ranking algorithms, both static and time-aware, and their applications to evolving networks and emphasize both the impact of network evolution on well-established static algorithms and the benefits from including the temporal dimension for tasks such as prediction of real network traffic, prediction of future links, and identification of highly-significant nodes.

Rate-optimal graphon estimation

TL;DR: This paper establishes optimal rate of convergence for graphon estimation in a H\"{o}lder class with smoothness $\alpha$, which is, to the surprise, identical to the classical nonparametric rate.

An Evolutionary Algorithm Approach to Link Prediction in Dynamic Social Networks

TL;DR: This work provides an approach to predicting future links by applying the Covariance Matrix Adaptation Evolution Strategy (CMA-ES) to optimize weights which are used in a linear combination of sixteen neighborhood and node similarity indices.

Hiding individuals and communities in a social network

TL;DR: It is shown that individuals and communities can disguise themselves from detection online by standard social network analysis tools through simple changes to their social network connections.

Who to follow and why: link prediction with explanations

TL;DR: WTFW ("Who to Follow and Why"), a stochastic topic model for link prediction over directed and nodes-attributed graphs, is proposed, which not only predicts links, but for each predicted link it decides whether it is a "topical" or a "social" link, and depending on this decision it produces a different type of explanation.

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

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.
