• Privacy-Preserving Distributed Learning with Nonsmooth Objective Functions 

      Gauthier, Francois; Gratton, Cristiano; Dasanadoddi Venkategowda, Naveen Kumar; Werner, Stefan (Chapter, 2021)
      This paper develops a fully distributed differentially-private learning algorithm based on the alternating direction method of multipliers (ADMM) to solve nonsmooth optimization problems. We employ an approximation of the ...
    • Privacy-preserving distributed machine learning for artificial intelligence of things 

      Gratton, Cristiano (Doctoral theses at NTNU;2023:12, Doctoral thesis, 2023)
      This thesis proposes machine learning algorithms that can be fully distributed over ad-hoc networks of machines/agents. Developing distributed algorithms for artificial intelligence is necessary since running machine-lea ...
    • Privacy-Preserving Distributed Maximum Consensus 

      Dasanadoddi Venkategowda, Naveen Kumar; Werner, Stefan (Peer reviewed; Journal article, 2020)
      We propose a privacy-preserving distributed maximum consensus algorithm where the local state of the agents and identity of the maximum state owner is kept private from adversaries. To that end, we reformulate the maximum ...
    • Privacy-preserving distributed precoder design for decentralized estimation 

      Dasanadoddi Venkategowda, Naveen Kumar; Werner, Stefan (Chapter, 2018)
      We study privacy-preserving precoder design for decentralized estimation in wireless sensor networks where the sensor nodes want their local information such as the channel state information, observation matrices, and ...
    • Quaternion-valued distributed filtering and control 

      Talebi, Sayed Pouria; Werner, Stefan; Mandic, Danilo (Peer reviewed; Journal article, 2020)
      This article presents a unified framework for filtering and control of quaternion-valued state vector processes through multiagent networked systems. To achieve this goal, the filtering problem in sensor networks is ...
    • Quickest Detection of Stochastic False Data Injection Attacks with Unknown Parameters 

      D'Avila Barros, Bettina; Kumar Dasanadoddi Venkategowda, Naveen; Werner, Stefan (Chapter, 2021)
      This paper considers a multivariate quickest detection problem with false data injection (FDI) attacks in internet of things (IoT) systems. We derive a sequential generalized likelihood ratio test (GLRT) for zero-mean ...
    • Recurrent Time-Varying Multi-Graph Convolutional Neural Network for Personalized Cervical Cancer Risk Prediction 

      Gogineni, Vinay Chakravarthi; Langberg, Geir Severin Rakh Elvatun; Naumova, Valeriya; Nygård, Jan Franz; Mari, Nygård,; Grasmair, Markus; Werner, Stefan (Chapter, 2021)
      Cervical cancer screening programs have reduced the incidence of cervical cancer, but suffer from over- and too infrequent screening as women’s risk of developing cervical cancer differs. Personalized risk prediction models ...
    • Renewable energy optimization with centralized and distributed generation 

      Leithon, Johann; Werner, Stefan; Koivunen, Visa (Chapter; Peer reviewed, 2018)
      We propose optimization strategies for cooperating households with renewable energy generation and storage facilities. We consider two configurations: 1) households with shared access to an energy farm, and 2) households ...
    • Resource-Aware Asynchronous Online Federated Learning for Nonlinear Regression 

      Gauthier, Francois; Gogineni, Vinay Chakravarthi; Werner, Stefan; Huang, Yih-Fang; Kuh, Anthony (Chapter, 2022)
      Many assumptions in the federated learning literature present a best-case scenario that can not be satisfied in most real-world applications. An asynchronous setting reflects the realistic environment in which federated ...
    • Securing the Distributed Kalman Filter Against Curious Agents 

      Moradi, Ashkan; Dasanadoddi Venkategowda, Naveen Kumar; Talebi, Sayedpouria; Werner, Stefan (Chapter, 2021)
      Distributed filtering techniques have emerged as the dominant and most prolific class of filters used in modern monitoring and surveillance applications, such as smart grids. As these techniques rely on information sharing ...
    • Storage management in a shared solar environment with time-varying electricity prices 

      Leithon, Johann; Werner, Stefan; Koivunen, Visa (Journal article; Peer reviewed, 2019)
      Internet of Things technologies will enable smart energy planning, which in turn will expedite the adoption of renewable energy (RE). In this paper, we propose a mathematical framework to optimize the use of RE in a shared ...
    • Tracking dynamic systems in alpha-stable environments 

      Talebi, Sayed Pouria; Werner, Stefan; Mandic, Danilo (Chapter, 2019)
      In order to accommodate for modern adaptive filtering applications, the classic adaptive filtering paradigm is considered from a more general perspective. The new formulation allows for time dependent variations in the ...
