Genuinely distributed Byzantine machine learning

Rachid Guerraoui, El Mahdi El Mhamdi, Le Nguyen Hoang, Sébastien Louis Alexandre Rouault, Arsany Hany Abdelmessih Guirguis

Machine learning (ML) solutions are nowadays distributed, according to the so-called server/worker architecture. One server holds the model parameters while several workers train the model. Clearly, such architecture is prone to various types of component ...

How Smart is the Grid?

François Maréchal, Luc Girardin, Ermanno Lo Cascio, Zhichuan Ma

Ancient Romans called urbs the set of buildings and infrastructures, and civitas the Roman citizens. Today instead, while the society is surfing the digital tsunami, urbs and civitas tend to become much closer, almost merging, that we might attempt to cond ...

Natural and anthropogenic variations in methane sources during the past two millennia

Jed Oliver Kaplan, Kristen Marie Krumhardt

Methane is an important greenhouse gas that is emitted from multiple natural and anthropogenic sources. Atmospheric methane concentrations have varied on a number of time scales in the past, but what has caused these variations is not always well understoo ...

2500 Years of European Climate Variability and Human Susceptibility

Jed Oliver Kaplan

Climate variations influenced the agricultural productivity, health risk, and conflict level of preindustrial societies. Discrimination between environmental and anthropogenic impacts on past civilizations, however, remains difficult because of the paucity ...

Multiproxy study of anthropogenic and climatic changes in the last two millennia from a small mire in central Poland

Mariusz Lamentowicz

The Żabieniec kettle-hole is the first peatland in central Poland analysed quantitatively with four biotic proxies (plant macrofossils, pollen, testate amoebae and chironomids) in order to reconstruct past environmental change. Palaeoecological data were s ...

Populating Ancient Pompeii with Crowds of Virtual Romans

Daniel Thalmann, Jonathan Maim, Barbara Yersin

Pompeii was a Roman city, destroyed and completely buried during an eruption of the volcano Mount Vesuvius. We have revived its past by creating a 3D model of its previous appearance and populated it with crowds of Virtual Romans. In this paper, we detail ...

Reviving the Roman Odeon of Aphrodisias: Dynamic Animation and Variety Control of Crowds in Virtual Heritage

Daniel Thalmann, Jonathan Maim, Sébastien Schertenleib, Pablo Stanislaw De Heras Ciechomski

In this paper we propose a new method for rendering crowds of virtual humans with dynamicallydeformed skeletons with levels of detail using two simple caching schemes for animations and geometry. Weshow how the virtual heritage project ERATO pushed for the ...
