  1. 1. 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

  3. 2. On Distributed Optimization in Networked Systems

  4. 3. Distributed Optimization with Nonconvexities and Limited Communication

    Författare :Sindri Magnússon; Carlo Fischione; Juan Miguel Morales González; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Distributed Optimization; Resource Allocation; Power Networks; Limited Communication; Nonconvex Optimization; Wireless Sensor Networks; Cyberphysical Systems.; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : In economical and sustainable operation of cyber-physical systems, a number of entities need to often cooperate over a communication network to solve optimization problems. A challenging aspect in the design of robust distributed solution algorithms to these optimization problems is that as technology advances and the networks grow larger, the communication bandwidth used to coordinate the solution is limited.

  5. 4. Decentralized Constrained Optimization: a Novel Convergence Analysis

    Författare :Firooz Shahriari Mehr; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Constrained optimization; Decentralized optimal transport; Distributed optimization; Multi-agent systems; Convergence analysis; Convex optimization;

    Sammanfattning : One reason for the spectacular success of machine learning models is the appearance of large datasets. These datasets are often generated by different computational units or agents and cannot be processed on a single machine due to memory and computing limitations. LÄS MER

  7. 5. Distributed Optimization in Time-Varying Environments

    Författare :Marie Maros; Joakim Jaldén; Alex Olshevsky; KTH; []
    Nyckelord :Distributed Optimization; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Solving optimization problems in a distributed manner is critical in many systems. Many relevant systems are distributed in nature in the sense that they consist of autonomous agents that are to come to a joint decision based on a certain metric. LÄS MER
