Yesterday a paper by Mason Porter, Hiroki Sayama and myself was published in Frontiers for Young Minds. It attempts to present network centrality to the Frozen generation. In the spirit of data sharing, you can find the raw data below. It is the undirected network of who talks to whom and how many lines they […]
Reproducing computational studies in general and general network dismantling in particular
June 21, that authors of the General Network Dismantling paper sent me a reply with their comments to this blog post. You can read it here. I will comment on it later. This post is about some recent experiences and thoughts of reproducing computational results of a paper. Thoughts about computational reproducibility Reproducibility of […]
Firsts in network science
This post is revised after comments from Urska Demsar, Travis Gibson, Des Higham, Mason Porter, Jan Peter Schäfermeyer, Johan Ugander, and Jean-Gabriel Young. Thanks! Our field is interdisciplinary and many smart people have been thinking about similar things. No wonder things get reinvented and rediscovered many times. I don’t think science is a competition to […]
The importance of being earnest about the importance of nodes
One of the problems network science sets out to solve is to find important nodes. Of course, what is important depends on the context, but an applied scientist coming to network science for an answer probably has a clear idea what it means in her study system. There is no shortage of methods in the […]
Steak-pun networks: The state of affairs
This is a comment on the recent arxiv by Voitalov, van der Hoorn, van der Hofstad and Krioukov titled Scale-free networks well done, and the ongoing debate of scale-free networks. As usual, I take a laid-back spectator position—no papers, no research of my own, just another blog post of my own reading of this contribution […]
Community detection: A consumer’s voice
In one of my first network projects, as a student, I studied how networks break down when you remove edges in order of their betweenness. Simultaneously, Girvan and Newman used exactly the same approach to make the first modern community detection algorithm. This was before authors used to make their code publicly available, so when […]
Hierarchies and networks
We scientists love the word “hierarchy”. In every professor, it evokes a picture of us chalking up a pyramid on the black board and confidently explaining “at the top, we have the …” Hierarchies are systematic and meaningful orderings. They are the successful ends of research projects; bringers of peace to our curious minds. They […]
