      In Fall 2014 we offered an online course CS 7637 Knowledge-Based Artificial Intelligence: Cognitive Systems (KBAI) to about 200 students as part of the Georgia Tech Online MS in CS program. We incorporated lessons from ...
    • Reasoning About Function in Reflective Systems 

      Stroulia, Eleni; Goel, Ashok K. (Georgia Institute of Technology, 1993)
      Functional models have been extensively investigated in the context of several problem-solving tasks such as device diagnosis and design. In this paper, we view problem solvers themselves as devices, use functional models ...
    • Some Experimental Results in Multistrategy Navigation Planning 

      Goel, Ashok K.; Ali, Khaled Subhi; Stroulia, Eleni (Georgia Institute of Technology, 1995)
      Spatial navigation is a classical problem in AI. In the paper, we examine three specific hypotheses regarding multistrategy navigation planning in visually engineered physical spaces containing discrete pathways: (1) For ...
    • Using Spatial Structure in the Associative Retrieval of 2-D Line Drawings 

      Yaner, Patrick W.; Goel, Ashok K. (Georgia Institute of Technology, 2002)
      We consider the problem of associative image retrieval, focusing on retrieval of 2-D line drawings by example. We represent 2-D line drawings as semantic networks of spatial elements and relations among them. We describe ...
