Topological data analysis of contagion maps for examining spreading processes on networks

Topological data analysis of contagion maps for examining spreading processes on networks | networks and network weaving | Scoop.it

Social and biological contagions are influenced by the spatial embeddedness of networks. Historically, many epidemics spread as a wave across part of the Earth’s surface; however, in modern contagions long-range edges—for example, due to airline transportation or communication media—allow clusters of a contagion to appear in distant locations. Here we study the spread of contagions on networks through a methodology grounded in topological data analysis and nonlinear dimension reduction. We construct ‘contagion maps’ that use multiple contagions on a network to map the nodes as a point cloud. By analysing the topology, geometry and dimensionality of manifold structure in such point clouds, we reveal insights to aid in the modelling, forecast and control of spreading processes. Our approach highlights contagion maps also as a viable tool for inferring low-dimensional structure in networks.

The Parable of Reddit or How Traditional Business Models Fail Communities

If you work in the community or digital space, it's been impossible not to follow the turmoil at Reddit during the last week. It is cause for a lot of anxiety in the community space because until this turmoil hit, Reddit was viewed as community success story - growing geometrically over the years.

Jigsaw percolation: What social networks can collaboratively solve a puzzle?

Jigsaw percolation: What social networks can collaboratively solve a puzzle? | networks and network weaving | Scoop.it

We introduce a new kind of percolation on finite graphs called jigsaw percolation. This model attempts to capture networks of people who innovate by merging ideas and who solve problems by piecing together solutions. Each person in a social network has a unique piece of a jigsaw puzzle. Acquainted people with compatible puzzle pieces merge their puzzle pieces. More generally, groups of people with merged puzzle pieces merge if the groups know one another and have a pair of compatible puzzle pieces. The social network solves the puzzle if it eventually merges all the puzzle pieces. For an Erdős–Rényi social network with n vertices and edge probability p_n, we define the critical value p_c(n) for a connected puzzle graph to be the p_n for which the chance of solving the puzzle equals 1/2. We prove that for the n-cycle (ring) puzzle, p_c(n)=Θ(1/log n), and for an arbitrary connected puzzle graph with bounded maximum degree, p_c(n)=O(1/log n) and ω(1/n^b)for any b>0. Surprisingly, with probability tending to 1 as the network size increases to infinity, social networks with a power-law degree distribution cannot solve any bounded-degree puzzle. This model suggests a mechanism for recent empirical claims that innovation increases with social density, and it might begin to show what social networks stifle creativity and what networks collectively innovate.

Fractal and Small-World Networks Formed by Self-Organized Critical Dynamics

Fractal and Small-World Networks Formed by Self-Organized Critical Dynamics | networks and network weaving | Scoop.it

We propose a dynamical model in which a network structure evolves in a self-organized critical (SOC) manner and explain a possible origin of the emergence of fractal and small-world networks. Our model combines a network growth and its decay by failures of nodes. The decay mechanism reflects the instability of large functional networks against cascading overload failures. It is demonstrated that the dynamical system surely exhibits SOC characteristics, such as power-law forms of the avalanche size distribution, the cluster size distribution, and the distribution of the time interval between intermittent avalanches. During the network evolution, fractal networks are spontaneously generated when networks experience critical cascades of failures that lead to a percolation transition. In contrast, networks far from criticality have small-world structures. We also observe the crossover behavior from fractal to small-world structure in the network evolution.
