2019 Fall Program for Executives @NECSI

July 25, 2019 Comments (0)

Organizations are operating in an increasingly complex global context. Business and society are transforming and becoming increasingly complex. Artificial Intelligence, machine learning, big data analytics and hybrid human-machine systems are playing an increasing role in business products, strategy, and in the organization itself. NECSI is hosting its two day Executive 2019 Fall Program in Washington, DC. Source: necsi-exec.org

Estimating the success of re-identifications in incomplete datasets using generative models

July 25, 2019 Comments (0)

While rich medical, behavioral, and socio-demographic data are key to modern data-driven research, their collection and use raise legitimate privacy concerns. Anonymizing datasets through de-identification and sampling before sharing them has been the main tool used to address those concerns. We here propose a generative copula-based method that can accurately estimate the likelihood of a specific person to be correctly re-identified, even in a heavily incomplete dataset. On 210 populations,...

Automatic Off-Line Design of Robot Swarms: A Manifesto

July 23, 2019 Comments (0)

Designing collective behaviors for robot swarms is a difficult endeavor due to their fully distributed, highly redundant, and ever-changing nature. To overcome the challenge, a few approaches have been proposed, which can be classified as manual, semi-automatic, or automatic design. This paper is intended to be the manifesto of the automatic off-line design for robot swarms. We define the off-line design problem and illustrate it via a possible practical realization, highlight the core research...

Entropy | Special Issue : Thermodynamics and Information Theory of Living Systems

July 23, 2019 Comments (0)

One of the defining features of living systems is their ability to process, exchange and store large amounts of information at multiple levels of organization, ranging from the biochemical to the ecological. At the same time, living entities are non-equilibrium—possibly at criticality—physical systems that continuously exchange matter and energy with structured environments, all while obeying the laws of thermodynamics. These properties not only lead to the emergence of biological information,...

Information Pollution by Social Bots

July 22, 2019 Comments (0)

Social media are vulnerable to deceptive social bots, which can impersonate humans to amplify misinformation and manipulate opinions. Little is known about the large-scale consequences of such pollution operations. Here we introduce an agent-based model of information spreading with quality preference and limited individual attention to evaluate the impact of different strategies that bots can exploit to pollute the network and degrade the overall quality of the information ecosystem. We find...

Complexity: Science, Engineering or a State of Mind? Towards a Scientific Renaissance

July 14, 2019 Comments (0)

Is complexity a Science? Is it a possibly useful new way of engineering? In this video narrated by Maxi San Miguel it will be argued that Complexity is a new way of thinking necessary for a scientific renaissance that can transform society. Source: www.youtube.com

Historical comparison of gender inequality in scientific careers across countries and disciplines

July 12, 2019 Comments (0)

There is extensive, yet fragmented, evidence of gender differences in academia suggesting that women are under-represented in most scientific disciplines, publish fewer articles throughout a career, and their work acquires fewer citations. Here, we offer a comprehensive picture of longitudinal gender discrepancies in performance through a bibliometric analysis of academic careers by reconstructing the complete publication history of over 1.5 million gender-identified authors whose publishing...

Embodied robots driven by self-organized environmental feedback

July 11, 2019 Comments (0)

Which kind of complex behavior may arise from self-organizing principles? We investigate this question for the case of snake-like robots composed of passively coupled segments, with every segment containing two wheels actuated separately by a single neuron. The robot is self-organized both on the level of the individual wheels and with respect to inter-wheel coordination, which arises exclusively from the mechanical coupling of the individual wheels and segments. For the individual wheel, the...

The Internet and your inner English tea merchant | Taha Yasseri | TEDxThessaloniki

July 11, 2019 Comments (0)

The Internet is a totally internet phenomenon. In this talk, Dr Taha Yasseri gives answers to burning internet questions. Are users biased like an English tea merchant? Why do we care more about some events and not about others? And for how long do we care? He presents research findings on collective memory on the internet, as well as on the threshold of death toll that attracts our attention and empathy when it comes to social media. Although the interned is constantly criticized as being a...
