Abstract de Mme Licia Amichi, INRIA Saclay

Abstract : Human mobility literature is limited in its ability to capture the novelty-seeking or the exploratory tendency of individuals. Mainly, the vast majority of mobility prediction models rely uniquely on the history of visited locations (as captured in the input dataset) to predict future visits. This hinders the prediction of new unseen places and reduces prediction accuracy. In our works, we show that a two-dimensional modeling of human mobility, which explicitly captures both regular and exploratory behaviors, yields a powerful characterization of users. Using such model, we identify the existence of three distinct mobility profiles with regard to the exploration phenomenon Scouters (i.e., extreme explorers), Routiners (i.e., extreme returners), and Regulars (i.e., without extreme behavior). Further, we extract and analyze the mobility traits specific to each profile. We then investigate temporal and spatial patterns in each mobility profile and show the presence of recurrent visiting behavior of individuals even in their novelty-seeking moments. Our results unveil important novelty preferences of people, which are ignored by literature prediction models. Finally, we show that prediction accuracy is dramatically affected by exploration moments of individuals. We then discuss how our profiling methodology could be leveraged to improve prediction. 

Abstract de Mr Philippe Jacquet, INRIA Saclay  : 

Abstract : With the rise of IoT with its billions of connected sensors and end device, we see the           possibility of mapping large areas and complex systems into digital twins. Many cities are building  their own digital twins whose components are updated in real time as the same pace as their          physical counterparts. There is the possibility for the rising a digital twin of large portions of the        world. The main technical issue the tackled in this vision, is the tremendous volume of distributed       updates in software and data, which such huge system would generate, and how to keep track of       them. One of the most promising architecture in this perspective is the blockchain, but after the            devastating energy impact of bitcoin (the per year equivalent energy consumption of Greece) there is a need to make it sustainable and scalable. We will present a new blockchain concept based on        green leader election. It would allow ledgers with a very high frequency of mining updates enduring  a dynamic between one to several thousand of billions of simultaneous miners. The new blockchain   would incur low or no pressure on network and would avoid any significant processing burden.

Abstract de Mr Emilio Strinati Calvanese, CEA-Leti, technology research institute,

Abstract: This talk promotes the idea that including semantic and goal-oriented aspects in future    6G networks can produce a significant leap forward in terms of system effectiveness and                      sustainability. Semantic communication goes beyond the common Shannon paradigm of                      guaranteeing the correct reception of each single transmitted packet, irrespective of the meaning     conveyed by the packet. The idea is that, whenever communication occurs to convey meaning or           to  accomplish a goal, what really matters is the impact that the correct reception/interpretation of     a packet is going to have on the goal accomplishment. Focusing on semantic and goal-oriented aspects, and possibly combining them,  helps to identify the relevant information, i.e. the                       information strictly necessary to recover the meaning intended by the transmitter or to accomplish       a goal. Combining knowledge representation and reasoning tools with machine learning algorithms     paves the way to build semantic learning strategies enabling current machine learning algorithms         to  achieve better interpretation capabilities and contrast adversarial attacks. 6G semantic networks    can bring semantic learning mechanisms at the edge of the network and, at the same time, semantic    learning can help 6G networks to improve their efficiency and sustainability.
