Generalized Nested Rollout Policy Adaptation with Limited Repetitions Tristan Cazenave https://lnkd.in/eecFpei9 Next Wednesday at EWRL in Toulouse, I will present a poster on an improvement to Monte Carlo Search with applications to RNA Design, TSPTW and Weak Schur numbers. Generalized Nested Rollout Policy Adaptation (GNRPA) is a Monte Carlo search algorithm for optimizing a sequence of choices. We propose to improve on GNRPA by avoiding too deterministic policies that find again and again the same sequence of choices. We do so by limiting the number of repetitions of the best sequence found at a given level. Experiments show that it improves the algorithm for three different combinatorial problems: Inverse RNA Folding, the Traveling Salesman Problem with Time Windows and the Weak Schur problem.

Transforming complex systems requires a portfolio of programs aimed at a common goal, not a strategy dictating how each sector or enterprise should solve its respective part of the challenge. Rather than trying to conceptualize the complexity away, today’s successful missions will make it central to policymaking https://lnkd.in/dimTDWiW

Do we need to create the network representation to know when the transition modular to nestedness happens? No, entropy is enough. Have a look!! Just out: https://lnkd.in/eiWrck-4.

How can companies upgrade the environmental sustainability of their supply chains? In a recent study funded by the Area of Excellence AI, Data science and Business at NEOMA Business School an co-authored with Samuel Fosso Wamba, PhD-HDR and Maciel M. Queiroz we highlight the positive impact of a #data-driven culture combined with the adoption of new #AI technologies to boost #corporate #sustainability. Our study shows that an organizational culture that promotes the smart use of data is a key factor in advancing corporate sustainability not only by its direct effect on the implementation of sustainable supply chain practices but also by its mediation effect on the relationship between a firm capability to develop, integrate, and reconfigure AI technologies and its environmental performance.

BREAKING NEWS: the long-awaited first official #workingpaper & #database of our PILLARS (EU Science, Research and Innovation) paper on occupation and industrial exposure to emerging digital technologies is out! We propose #NLP-based methodology to compute the #exposure scores of #ISCO-08 occupations and #NACE Rev.2 industries to 40 distinct #emerging technologies such as #ML, #robots, #IoT, among others. The combined effect of all emerging technologies on regional #European #employment appears positive. However, the individual effect varies across technologies. How exactly?

My colleagues from our French branch, Maxime Audinet, PhD and Colin Gerard, PhD, recently published an analysis of Russia’s ecosystem of information influence following the invasion of Ukraine. Figure 5 provides insight into this complex system, highlighting a layered structure in which state-controlled actors collaborate with private entities and informal networks to project influence worldwide. The spillover of the conflict into the international media environment has led to the partial expulsion of Russian state-controlled media outlets RT and Sputnik from most Western countries, spearheaded by the EU. In response, both networks have adapted by fragmenting their digital infrastructure, "clandestinizing" certain content, and shifting focus to new audience bases, particularly in sub-Saharan Africa. 📍 Full article: https://lnkd.in/emGdWix2

🚨 New OA publication 📢 In this conceptual contribution w/ Patrick Donges and Christian Pentzold in IJoC, we propose a communicative framework for the analysis of persistent distinctions between center and periphery in the digital public sphere. 🔎 We argue that in the digital public sphere, four distinct modes of recognition emerge: attention, resonance, allegiance, and engagement. These modes of recognition can carry positive or negative valence. ⚡ The four modes induce persistent yet contingent center-periphery distinctions among actors, issues, and even entire arenas. Some strive for a position of centrality, while others exhibit a purposive orientation toward peripheries rather than centers. We discuss the role of digital platforms and implications for public sphere theory. https://lnkd.in/emEYugRq Center for Digital Participation

Dawid Hanak and others are making serious criticisms of the structures of knowledge dissemination, and its distorting pressures on researchers created by citation counts, the hierarchy of journals, often a flawed refereeing system, and the imposed financial prices of publication which no longer reflect genuine marginal economic costs. As a former Editor in Chief of two journals, I have full sympathy with these criticisms. But my main criticism of the current system - as it applies to my field of study, and possibly other similar fields in the public policy area - is different. The current structures seriously distort understanding of the history of the subject, and inhibit its scientific development. This arises because of the imposed distinction between 'true' research (ie that published in the journals published by the same companies who run the citation indexes) and the 'grey literature', deemed to be second class, with lower quality standards, including vanity publishing and promotional or advertorial propaganda. That may well be a valid picture in some fields, but it is simply not a truthful description how transport science and transport policy assessment has developed. Much of the foundation work has actually been carried out and published in the Government scientific service, in local government bodies, in companies, in Government Commissions and Parliamentary inquiries, in independent advisory bodies, by consultants commissioned by industry of Government, and in a host of think tanks and advisory bodies. Academics have of course been active in all of these, but a substantial portion of their work has then been published under Government covers, or by their own academic institutes. (Yes, and a substantial proportion of not very good work as well. Just like the journals). The intellectual debates around their validity are held in the formal processes of Public Examination, Committees, Parliamentary Inquiries, and indeed sometimes the Courts. The journals have had a role in this, but their schedules are much slower than the rate at which the procedures themselves evolve. All this has strengths and weakness of course. But as a rule of thumb, I would say that somewhere around half of all the highest quality work is published in the 'grey' literature. If you use a search criterion for a literature review based on the citation counts of the academic journals, you would simply miss many of the most important references. (Google Scholar, in my experience, is better, since it includes the official sources). A longer version of this post, with examples and details, is available (free to view of course!) in Local Transport Today's 'Tapas' network, at https://lnkd.in/dQYdrh3P (One caveat: I was fortunate enough to get my first senior academic appointment before the citation count system became embedded. I'm not recommending now that you ignore it! But don't rely on it for scientific understanding).

https://lnkd.in/eeNMnwer Excerpts: "Assessments of all types of AI impact are urgently needed. [...] here we call on researchers to develop a set of policy-relevant scenarios to quantify the effects that AI expansion could have on the climate under a range of assumptions. Routinely used by financial institutions to understand risks and opportunities and plan investments, scenarios combine quantitative models with expert consultations. Rather than making predictions, they explore many possible futures based on influential factors. [...] Could AI take the world to a more radically green future, or a more dystopian one?"
