## The Network Paradigm

In this video we look at what we call the network paradigm, a paradigm is the set of methods and assumptions underlying a particular scientific domain as such it constitutes a whole way seeing...

## Network Paradigm

Network Paradigm All models and theories are like windows onto the world. None of them are perfect. They all enable us to see some things but also inhibit us from seeing others, and more...

## Network Science

Network Science Network science is the area of science and mathematics that tries to analyze and interpret networks based upon data and the use of computer software. Network science is supported...

## Graph Theory

Graph Theory In the formal language of mathematics, a network is called a graph, and graph theory is the area of mathematics that studies these objects called graphs. Graph theory is a relatively...

## Degree of Connectivity

Degree of Connectivity The degree of connectivity to a node in a network is a measure of the number of in and out links the node has to other nodes. This degree of connectivity can be interpreted...

## Network Topology

Network Topology Network topology refers to the overall make-up and structure to a network, with the word topology meaning the way in which constituent parts are interrelated or arranged. Within...

## Network Connectivity

Network Connectivity One of the defining features of a network is its overall degree of connectivity, which might qualify as the defining feature. Going from a system with a low degree of...

## Network Diameter

Network Diameter The size of a network is important not so much because of the sheer quantity of elements we are dealing with, but more because it sets the context for how close or far on average...

## Network Degree Distribution

Network Degree Distribution A key parameter to the make-up of any network is the network’s degree distribution. Degree distribution tries to capture the difference in the degree of connectivity...

## Network Clustering

Network Clustering The way in which a network is connected plays a large part in how we analyze and interpret it. When analyzing connectedness and clustering, we are asking how integrated or...

## Network Dynamics

Network Dynamics The study of how networks form, grow and change over time is a relatively new area of research, but it is critical to understand how to foster the development of some types of...

## Network Robustness

Network Robustness Robustness & resilience are often thought of in terms of a system’s capacity to maintain functionality in the face of external perturbations. We see some...

## Network Diffusion & Contagion

Network Diffusion & Contagion How something spreads across a network is a key question of interest when analyzing many different networks, the classical example of this being the diffusion of...

## Centralized & Power Law Networks

Centralized & Power Law Networks Centralized networks represent networks with a very high degree distribution, meaning in this type of network structure there will be very many nodes with a...

## Decentralized & Small World Networks

Decentralized & Small World Networks A decentralized network is one without any overall dominant central hub. But instead, a network that has some nodes with a higher degree of connectivity...

## Random & Distributed Networks

Random & Distributed Networks A random network is more formally termed the Erdős–Rényi random graph model, so named after two mathematicians who first introduced a set of models for random...

## Network Centrality

Network Centrality Centrality is a measure that tells us how influential or significant a node is within the overall network. This concept of significance will have different meanings depending...

## Complex Contagion

Complex Contagion Complex contagion is the phenomenon in social networks in which multiple sources of exposure to some alteration are required before an individual adopts the change of behavior....

## Network Effects

Network Effects The network effect arises when users gain value from others using the same network. The more people that join the more value for everyone else, this dynamic is driven by positive...

## Multiplex Networks

Multiplex Networks A multiplex network is a network model composed of a multiplicity of overlapping networks that capture the different types of connections between nodes within the network. When...
