Talk Title: Large scale neuroimaging and neuromodulation to promote motor recovery after stroke
Series: Seminars in BME (Lab Rotations)
Abstract: Stroke is a leading cause of adult long term disability, and up to 2/3 of stroke survivors do not fully recover, despite intensive therapy. Identifying and personalizing rehabilitation treatments based on each patient's neurological and behavioral profile could greatly enhance the post-stroke outcomes. In this talk, I will discuss a two-pronged approach to address this problem. First, we are characterizing how specific neuroanatomical changes relate to motor recovery on a large scale. In partnership with ENIGMA Center for Worldwide Medicine, Imaging, and Genomics, we have developed an ENIGMA working group on stroke recovery to harmonize stroke neuroimaging efforts around the world, with an initial goal of n>3000 MRIs. Our preliminary data shows promising results, with specific post-stroke neuroanatomical motor regions relating to motor impairment and recovery, and results becoming more robust as data across sites is combined. Second, we are developing and evaluating neuromodulatory approaches to affect brain activity in key regions after stroke, using noninvasive brain stimulation and brain computer interfaces to enhance therapeutic outcomes. Preliminary work using transcranial direct current stimulation, real-time fMRI connectivity neurofeedback and a portable EEG-based virtual reality neurofeedback system will be discussed, along with future implications of this work for translational research.

NL Seminar-THE LIMITS OF UNSUPERVISED SYNTAX AND THE IMPORTANCE OF GROUNDING IN LANGUAGE ACQUISITION

Speaker: Yonatan Bisk, USC/ISI
Talk Title: THE LIMITS OF UNSUPERVISED SYNTAX AND THE IMPORTANCE OF GROUNDING IN LANGUAGE ACQUISITION
Series: Natural Language Seminar
Abstract: The future of self driving cars, personal robots, smart homes, and intelligent assistants hinges on our ability to communicate with computers. The failures and miscommunications of Siri style systems are untenable and become more problematic as machines become more pervasive and are given more control over our lives. Despite the creation of massive proprietary datasets to train dialogue systems, these systems still fail at the most basic tasks. Further, their reliance on big data is problematic. First, successes in English cannot be replicated in most of the six thousand plus languages of the world. Second, while big data has been a boon for supervised training methods, many of the most interesting tasks will never have enough labeled data to actually achieve our goals. It is, therefore, important that we build systems which can learn from naturally occurring data and grounded, situated interactions.
In this talk I will discuss work from my thesis on the unsupervised acquisition of syntax which harnesses unlabeled text in over a dozen languages. This exploration leads us to novel insights into the limits of semantics free language learning. Having isolated these stumbling blocks I will then present my recent work on language grounding where we attempt to learn the meaning of several linguistic constructions via interaction with the world.
Biography: Yonatan Bisk has research that focuses on Natural Language Processing from naturally occurring data unsupervised and weakly supervised data. He is a postdoc researcher with Daniel Marcu at USCs Information Sciences Institute. Previously, he received his PhD from the University of Illinois at Urbana Champaign under Julia Hockenmaier and his BS from the University of Texas at Austin.
