BREAKING: Coronavirus update--Italy, Iran, Germany, France, Spain and US have large jumps in new domestic transmissions. South Korea has second day of decline. (Today's attached map uses worldometers numbers)

China new cases are the best since the lockdown on Jan 23.

Update: China just reported only 125 cases today. 114 in Hubei province, down from 195 yesterday. This additional dramatic drop shows the effectiveness of travel restrictions and lockdowns.
If you want to understand what’s going on with the #coronavirus, this is the most informative article I have seen yet Definitely worth reading.

Community detection with the Label Propagation Algorithm: A survey

https://www.sciencedirect.com/science/article/pii/S0378437119312026

Highlights
• The Label Propagation Algorithm (LPA) has caught attention for its advantages.
• Abundant literature finds LPA efficient, scalable, conceptually clear, and simple.
• We review LPA-related proposals, including enhancements and extensions.
• An empirical study of 13,834 variants of LPA is presented.
• Experiments indicate that most enhancements are beneficial in specific scenarios.

Abstract
Community detection aims at discovering the structure, behavior, dynamics, and organization of a complex network by finding cohesive groups where nodes (entities) are, in some sense, more similar within the group and groups are in some fashion separated from the other groups. The Label Propagation Algorithm (LPA), which mimics epidemic contagion by spreading labels, is a popular algorithm for this task. Its variants (enhancements, extensions, combinations) seek to improve or to adapt it while preserving the advantages of the original formulation. This survey gathers, classifies, and summarizes LPA-related advances from 2007 to mid 2019. We also experiment with combinations of numerous LPA “building blocks” on two types of small synthetic networks; essentially all of the 13,834 resulting LPA variants have their niche in terms of either higher solution quality or lower computational load with acceptable quality, but none is universally superior.
💰 We are training 120 #PhD students in four annual cohorts of 30 students across the five partner universities

💰#PhD Position: Networks of the Coast.

This project focuses on social data analysis, collective decision making and governance. Possible topics are to analyse coastal land use, marine traffic and decision making related to biodiversity conservation.

We use modern data analysis methods to both ecological and social data. In addition mathematical models will be used to explain phenomena seen in the data or to form new hypothesis that can be tested with data sets.

3.4% Mortality Rate estimate by the World Health Organization (WHO) as of March 3

“Globally, about 3.4% of reported COVID-19 cases have died. By comparison, seasonal flu generally kills far fewer than 1% of those infected.”

💰 We are seeking applicants for a #PhD 3-year scholarship for an interdisciplinary project funded by CNRS

This project seeks to combine the neuroscience and the economic methods to study how humans behave in strategic environments. Economics has developed different models of learning in repeated games. Recent advances in human reinforcement learning suggest systematic distortions in value update. The project will look for ways to intertwine these aspects from a theoretical, computational and experimental perspectives.

Applicants will have a strong quantitative background, a taste for game theory and experimental methods and be open to work with both neuro-scientists and economists. The successful candidate will be based at the Laboratoire de Neurosciences Cognitives et Computationelles (DEC) and the Paris School of Economics (PSE).

If you are interested, please address before March 31th an email (with detailed CV) to:
stefano.palmineteri@ens.fr and jean-marc.tallon@psemail.eu

Roughly a week ago, some very smart person* sat down, drew this graph, and saved lives.
