      Ma, Yujunrong; Wu, Jiahao; Bhattacharyya, Shuvra S.; Boutellier, Jani (IEEE, 14.05.2020)
      article
      Dynamic dataflow models of computation have become widely used through their adoption to popular programming frameworks such as TensorFlow and GNU Radio. Although dynamic dataflow models offer more programming freedom, they ...
    • Homotopy Continuation for Sensor Networks Self-Calibration 

      Ferranti, Luca; Åström, Kalle; Oskarsson, Magnus; Boutellier, Jani; Kannala, Juho (IEEEEuropean Association for Signal Processing (EURASIP), 08.12.2021)
      article
      Given a sensor network, TDOA self-calibration aims at simultaneously estimating the positions of receivers and transmitters, and transmitters time offsets. This can be formulated as a system of polynomial equations. Due ...
    • I Trust You Dr. Researcher, but not the Company that Handles My Data –Trust in the Data Economy 

      Rousi, Rebekah; Piispanen, Joni-Roy; Boutellier, Jani; Bui, Tung X. (University of Hawaii, 03.01.2024)
      article
      In the rising era of artificial intelligence (AI), learning machinery and hyper surveillance, trust is a sought-after attribute. The General Data Protection Regulation (GDPR) was introduced to increase individuals’ control ...
