    • Anchoring and Agreement in Syntactic Annotations 

      Berzak, Yevgeni; Huang, Yan; Barbu, Andrei; Korhonen, Anna; Katz, Boris (Center for Brains, Minds and Machines (CBMM), arXiv, 2016-09-21)
      Published in the Proceedings of EMNLP 2016 We present a study on two key characteristics of human syntactic annotations: anchoring and agreement. Anchoring is a well-known cognitive bias in human decision making, where ...

    • The Compositional Nature of Event Representations in the Human Brain 

      Barbu, Andrei; Narayanaswamy, Siddharth; Xiong, Caiming; Corso, Jason J.; Fellbaum, Christiane D.; e.a. (Center for Brains, Minds and Machines (CBMM), arXiv, 2014-07-14)
      How does the human brain represent simple compositions of constituents: actors, verbs, objects, directions, and locations? Subjects viewed videos during neuroimaging (fMRI) sessions from which sentential descriptions of ...

    • Do You See What I Mean? Visual Resolution of Linguistic Ambiguities 

      Berzak, Yevgeni; Barbu, Andrei; Harari, Daniel; Katz, Boris; Ullman, Shimon (Center for Brains, Minds and Machines (CBMM), arXiv, 2016-06-10)
      Understanding language goes hand in hand with the ability to integrate complex contextual information obtained via perception. In this work, we present a novel task for grounded language understanding: disambiguating a ...

    • Seeing is Worse than Believing: Reading People’s Minds Better than Computer-Vision Methods Recognize Actions 

      Barbu, Andrei; Barrett, Daniel P.; Chen, Wei; Narayanaswamy, Siddharth; Xiong, Caiming; e.a. (2015-12-10)
      We had human subjects perform a one-out-of-six class action recognition task from video stimuli while undergoing functional magnetic resonance imaging (fMRI). Support-vector machines (SVMs) were trained on the recovered ...

    • Seeing What You’re Told: Sentence-Guided Activity Recognition In Video 

      Siddharth, Narayanaswamy; Barbu, Andrei; Siskind, Jeffrey Mark (Center for Brains, Minds and Machines (CBMM), arXiv, 2014-05-29)
      We present a system that demonstrates how the compositional structure of events, in concert with the compositional structure of language, can interplay with the underlying focusing mechanisms in video action recognition, ...
