Our work on the trajectories of scientists in the knowledge space has been published in EPJ Data Science @epj_ds! We show that tools for studying human mobility can be applied to the mobility within scientific knowledge.🧵

New paper from the team just published in Physica A! We propose a novel fitting method for rank-size distributions beyond Zipf's law, and apply it to the case of commit distributions of open-source repositories in Github.

People ask me, "Hey unfashionable Bayesian man, how can I fit those rad generative network models from your course?" Well with @danielj_redhead @mindismoving we wrote a package to make it easy. Easier. Okay it's possible now. Open access and open source. besjournals.onlinelibrary.wi…

Now out: "Contagion dynamics on higher-order networks" (arxiv.org/abs/2402.14938). This is a focused review of the topic that also proposes a unified formalism covering most of the functional forms used for the spreading dynamics and discusses a roadmap for empirical validation.

Yes, wow. A visualization library that omits data (!). Is this the only paper affected by this? It is always a good idea to look at the data directly
Wow. A bug in the Seaborn data visualization software hid many CD=1 papers, leading Park et al to incorrectly conclude that disruption in science and technology is declining (top histogram), while it is not ( bottom histogram). @VincentGinis
Collectively, these trajectories form mobility flows that follow a gravity model, favouring jumps in high-density areas and making long-distance moves less likely.
This work opens up the possibility of using this space to quantify how interventions (such as funding) modify trajectories and the structure of the space.
Collaborative work with @chakresh_iitgn @luyibov Fabrice Lecuyer and @m_starnini. And thanks to the comments on our preprint in this previous thread for helping us improve the work!

In our last @arxiv preprint, we studied mobility patterns in the knowledge landscape made of... @arxiv preprints!
We show that scientific trajectories of researchers in a low-dimensional embedding of 1.5M arxiv papers closely resemble physical mobility.

Using low-dimensional embedding techniques, we created a knowledge space composed of 1.5 million articles in physics, computer science, and mathematics. The analysis of individual publication histories reveals patterns of knowledge mobility similar to physical mobility.
