   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wireless Communications; Machine Learning; Over-the-Air Computation; Federated Learning; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : With the emerging Internet of Things (IoT) paradigm, more than a billion sensing devices will be collecting an unprecedented amount of data. Simultaneously, the field of data analytics is being revolutionized by modern machine learning (ML) techniques that enable sophisticated processing of massive datasets. LÄS MER

3. 2. Modeling and constructing unstructured overlay networks: Algorithms, techniques and the Smart Grid case

   Författare :Georgios Georgiadis; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; matching; smart grid; online computation; scheduling; unstructured overlays; random walks; natural computing; resistor networks; clustering;

   Sammanfattning : Throughout its lifetime, the Internet was always associated with overlay networks; from the WorldWideWeb and peer-to-peer networks to blogs and social networking solutions, overlays built on the Internet infrastructure gave it additional value and made it more engaging to everyday users. Today, rising overlay networks such as the Smart Grid as well as a multitude of sensor, mobile andwireless networks herald a new era of unprecedented connectivity and networking. LÄS MER

4. 3. Distributed Optimization and Control : Primal--Dual, Online, and Event-Triggered Algorithms

   Författare :Xinlei Yi; Karl H. Johansson; Dimos V. Dimarogonas; John S. Baras; Antonis Papachristodoulou; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Distributed nonconvex optimization; distributed online convex optimization; distributed event-triggered control; primal-dual algorithm; stochastic gradient descent; zeroth-order algorithm; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : In distributed optimization and control, each network node performs local computation based on its own information and information received from its neighbors through a communication network to achieve a global objective. Although many distributed optimization and control algorithms have been proposed, core theoretical problems with important practical relevance remain. LÄS MER

5. 4. Graph-based Analytics for Decentralized Online Social Networks

   Författare :Amira Soliman; Sarunas Girdzijauskas; Eiko Yoneki; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Decentralized Community Detection; Community-aware Learning; Spam Detection; Identity Validation; Informations- och kommunikationsteknik; Information and Communication Technology;

   Sammanfattning : Decentralized Online Social Networks (DOSNs) have been introduced as a privacy preserving alternative to the existing online social networks.  DOSNs remove the dependency on a centralized provider and operate as distributed information management platforms. LÄS MER

7. 5. Safe Autonomy under Uncertainty: Computation, Control, and Application

   Författare :Yulong Gao; Karl H. Johansson; Lihua Xie; ‪Frank Allgöwer; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Safe autonomy; shared autonomy; probabilistic controlled invariant set; invariant cover; linear temporal logic; temporal logic tree; safe teleoperation; automated car overtaking; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : Safety is a primary requirement for many autonomous systems, such as automated vehicles and mobile robots. An open problem is how to assure safety, in the sense of avoiding unsafe subsets of the state space, for uncertain systems under complex tasks. LÄS MER
