      This paper addresses the classification problem for a set of autonomous robots that interact with each other. The objective is to classify agents that "behave" in "different way", due to their own physical dynamics or ...
    • Decentralized Degree Regularization for Multi-Agent Networks 

      Yazıcıoğlu, A. Yasin; Egerstedt, Magnus B.; Shamma, Jeff S. (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 2013-12)
      Networked multi-agent systems are widely modeled as graphs where the agents are represented as nodes and edges exist between the agents that interact directly. In this setting, the degree of a node is the number of edges ...
    • Decentralized Formation of Random Regular Graphs or Robust Multi-Agent Networks 

      Yazıcıoğlu, A. Yasin; Egerstedt, Magnus B.; Shamma, Jeff S. (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 2014-12)
      Multi-agent networks are often modeled via interaction graphs, where the nodes represent the agents and the edges denote direct interactions between the corresponding agents. Interaction graphs have significant impact on ...

      Lee, Daniel (2016-03-09)
      Current artificial intelligence systems for perception and action incorporate a number of techniques: optimal observer models, Bayesian filtering, probabilistic mapping, trajectory planning, dynamic navigation, and feedback ...
    • Decoding Children’s Social Behavior 

      Rehg, James M.; Abowd, Gregory D.; Rozga, Agata; Romero, Mario; Clements, Mark A.; Sclaroff, Stan; Essa, Irfan; Ousley, Opal Y.; Li, Yin; Kim, Chanho; Rao, Hrishikesh; Kim, Jonathan C.; Presti, Liliana Lo; Zhang, Jianming; Lantsman, Denis; Bidwell, Jonathan; Ye, Zhefan (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 2013-06)
      We introduce a new problem domain for activity recognition: the analysis of children’s social and communicative behaviors based on video and audio data. We specifically target interactions between children aged 1–2 ...
    • Decoupling Behavior, Perception, and Control for Autonomous Learning of Affordances 

      Hermans, Tucker; Rehg, James M.; Bobick, Aaron F. (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 2013-05)
      A novel behavior representation is introduced that permits a robot to systematically explore the best methods by which to successfully execute an affordance-based behavior for a particular object. The approach decomposes ...
    • Deep Segments: Comparisons between Scenes and their Constituent Fragments using Deep Learning 

      Doshi, Jigar; Mason, Celeste; Wagner, Alan; Kira, Zsolt (Georgia Institute of Technology, 2014-09)
      We examine the problem of visual scene understanding and abstraction from first person video. This is an important problem and successful approaches would enable complex scene characterization tasks that go beyond ...
