Complexity matters: the fiftieth anniversary of Philip Anderson’s landmark essay ‘More is Different’.
https://www.nature.com/articles/s41567-022-01734-5
The point of More is Different is that a reductionist approach does not imply a ‘constructionist’ one. One cannot use the laws learned at a certain scale as building blocks to directly explain the emergent properties at higher scales. Reality is a collection of layers of emergence, and all the laws and frameworks needed to understand them share the same universal and fundamental quality. From this perspective, chemistry is not just applied physics, biology is not just applied chemistry — all the way up to sociology, which is not just applied psychology.

Information theory: A foundation for complexity science
Amos Golan and John Harte
https://www.pnas.org/doi/abs/10.1073/pnas.2119089119?af=R
Abstract
Modeling and inference are central to most areas of science and especially to evolving and complex systems. Critically, the information we have is often uncertain and insufficient, resulting in an underdetermined inference problem; multiple inferences, models, and theories are consistent with available information. Information theory (in particular, the maximum information entropy formalism) provides a way to deal with such complexity. It has been applied to numerous problems, within and across many disciplines, over the last few decades. In this perspective, we review the historical development of this procedure, provide an overview of the many applications of maximum entropy and its extensions to complex systems, and discuss in more detail some recent advances in constructing comprehensive theory based on this inference procedure. We also discuss efforts at the frontier of information-theoretic inference: application to complex dynamic systems with time-varying constraints, such as highly disturbed ecosystems or rapidly changing economies.

So you think you know the slope of your power-law?

Link: bit.ly/3AgmOmr
My aim in this talk is to discuss the potential pitfalls that one faces in such efforts and to promote a Bayesian interpolation framework for this purpose. I assume "power law scaling" is indeed present in the data, and discuss the difficulties and pitfalls in estimating the exponent. I do this both for synthetic and real data. Establishing that a "power law scaling" is indeed present is much more difficult. This talk is based on Davidovich & Roudi, Bayesian interpolation for power laws in neural data analysis, arXiv:2204.08525

#PhD and #postdoc position at Saarland University.
’m building up a new “chair” (= research group) for Societal Computing at Saarland University (https://saarland-informatics-campus.de/en/). Societal Computing comprises both (i) computing _of_ society, i.e. the measurement and analysis of societal phenomena, and (ii) computing _for_ society, i.e. working with partners to improve things based on the obtained insights.
https://ingmarweber.de/publications/.
For my new group, I’m looking for motivated PhD students and postdocs who are enthusiastic about interdisciplinary data science with applications in these or similar areas. In terms of methodological expertise, I’m open for a range of profiles that include some computational experience. Of particular relevance is experience in studying societal phenomena using non-traditional data sources, such as social media, satellite imagery, or mobile phone records.
To qualify for a PhD student position, a MA/MSc in computer science or similar is required by the university. Applicants who hold only a BA/BSc are encouraged to get in touch. However, they will most likely be required to first take additional coursework.
To qualify for a postdoc position, a strong publication record is required. The publication record should include at least some work with an application to studying a societal issue.
All positions are 100% (in the German system) following the corresponding public pay scale. Specifics depend on marital status and other factors, but general information can be found at https://academicpositions.com/career-advice/phd-postdoc-and-professor-salaries-in-germany, https://fastepo.com/phd-and-postdocs-salary/phd-students-and-postdocs-salary-germany-2020/, or on similar websites.
To apply, please send a CV and, ideally, academic transcripts to ingmar.weber@uni-saarland.de
Applications will be considered on a rolling basis until positions are filled. For full consideration please apply by Sunday, September 11.

سلام به همگی. بعد از یه رخوت شش ماهه کار مقاله‌خوانی رو از سر گرفتیم و امیدوارم این‌بار منقطع نشه. تو این دوره هرچند ماه یک تم برای مقاله‌ها در نظر میگیریم که شاید مفیدتر بشه. تم چند ماه آینده بیماری آلزایمر خواهد بود و سعی میکنیم مقالات مهم رو در حدود یک دهه اخیر مرور کنیم. این مقالات قبل از اینکه اینجا ارایه بشن، سه‌شنبه‌ها در جلساتی که در موسسه رهیافت برگزار میشه بررسی میشن. من خیلی دوست دارم که کانال یوتیوبی هم که داریم فعال بشه که البته با شرایط اینترنت موجود کار آسونی نیست. از پیشنهادات دوستان استقبال میکنیم.
