AI Seminar
Fri, Apr 21, 2017 @ 11:00 AM - 12:00 PM
Information Sciences Institute
Conferences, Lectures, & Seminars
Speaker: Homa Hosseinmardi , Danaher Corporation
Talk Title: Multimodal Labeling and Characterization of Social Network Data for Detection/Prediction of Cyberbullying
Abstract: One of the most pressing problems in high schools is bullying. However, with todays online and mobile technologies, bullying is moving beyond the schoolyards via cell phones, social networks, online text, videos, and images. As bad as fighting and bullying were before the internet age, the recording and posting of hurtful content online have magnified the harmful reach of bullying, enabling it 24 7. Cyberbullying is a growing problem and incidents of cyberbullying with extreme consequences such as suicide are routinely reported in popular press now. This talk provides insights into the problem of cyberbullying in social networks by investigating profanity usage, ground truth labeling of cyberbullying, and characterization of relationships between cyberbullying and a variety of factors, including linguistic content, social graph features, temporal commenting behavior, and multimedia modality. It also looks at the propagation of cyberbullying behavior in a social network, and prediction of victims of such behavior.
Biography: Homa Hosseinmardi holds PhD in Computer Science from the University of Colorado Boulder. She joined Danaher Corporation in 2015 as Data Scientist at Danaher Labs. She also contributes as a researcher at the CU CyberSafety Research Center. Hosseinmardis interests lie in the area of computational social science and data mining. She is particularly interested in the use of large scale datasets and machine learning techniques to study problems with internet safety, misbehavior and cyberbullying. Her recent work has focused on studying triggers of cyberaggressive behaviors. Her past work also addressed various questions toward understanding cyberbullying in online social networks.

Talk Title: Programming cells to build tissues with synthetic biology molecular tools: a new pathway towards engineering development and regeneration
Series: Seminars in BME (Lab Rotations)
Abstract: During embryonic development, complex multicellular tissues form based on genetically encoded algorithms that specify how cells will behave both individually and collectively.
In the Tissue Development Engineering Laboratory we develop synthetic biology approaches to implement in cells such self-organization programs and understand their overall logic, both for basic understanding and applications in regenerative medicine.
We have recently engineered and characterized a family of orthogonal cell-cell communication pathways, inspired by the mechanism of an endogenous communication system called Notch, which allows a cell to detect molecular signals from its neighbors and, in response, to induce user-specified transcriptional programs. These synthetic Notch pathways do not crosstalk with native pathways or with each other, thus providing multiple novel channels for engineering cell-cell communication. I will show how we used these synthetic pathways to flexibly construct basic routines for multi-cellular patterning and morphogenesis in mammalian cellular systems, e.g. localized differentiation, spatial patterning and Boolean decisions. Then, using the synthetic pathways in combination with adhesion molecules we designed a series of synthetic morphogenetic programs in 3D spheroids that deterministically drive spatial reorganization and symmetry breaking in a dynamic, self-organized fashion; we show that these trajectories are robust to perturbations and capable of self-regeneration. I will discuss possible applications of these technologies for developmental biology and regenerative medicine research and applications, especially in combination with tissue engineering tools and approaches. With the increasingly sophisticated synthetic biology components available today and the developments of tissue engineering we are going towards the possibility of designing the development of functional tissues in a dish with user-defined high level properties like shape, resistance to injury, regeneration, for the next generation of regenerative medicine applications.

NL Seminar - REINFORCEMENT LEARNING OF NEGOTIATION DIALOGUE POLICIES
Fri, Apr 21, 2017 @ 03:00 PM - 04:00 PM
Information Sciences Institute
Conferences, Lectures, & Seminars
Speaker: Kallirroi Georgila , USC/ICT
Talk Title: REINFORCEMENT LEARNING OF NEGOTIATION DIALOGUE POLICIES
Series: Natural Language Seminar
Abstract: The dialogue policy of a dialogue system decides on what dialogue move also called action, the system should make given the dialogue context also called dialogue state. Building hand crafted dialogue policies is a hard task, and there is no guarantee that the resulting policies will be optimal. This issue has motivated the dialogue community to use statistical methods for automatically learning dialogue policies, the most popular of which is reinforcement learning RL. However, to date, RL has mainly been used to learn dialogue policies in slot filling applications e.g. restaurant recommendation, flight reservation, etc. largely ignoring other more complex genres of dialogue such as negotiation. This talk presents challenges in reinforcement learning of negotiation dialogue policies. The first part of the talk focuses on applying RL to a two party multi issue negotiation domain. Here the main challenges are the very large state and action space, and learning negotiation dialogue policies that can perform well for a variety of negotiation settings, including against interlocutors whose behavior has not been observed before. Good negotiators try to adapt their behaviors based on their interlocutors' behaviors. However, current approaches to using RL for dialogue management assume that the users behavior does not change over time. In the second part of the talk, I will present an experiment that deals with this problem in a resource allocation negotiation scenario.
Biography: Kallirroi Georgila is a Research Assistant Professor at the Institute for Creative Technologies ICT at the University of Southern California US and at USCs Computer Science Department. Before joining USC ICT in 2009 she was a Research Scientist at the Educational Testing Service ETS and before that a Research Fellow at the School of Informatics at the University of Edinburgh. Her research interests include all aspects of spoken dialogue processing with a focus on reinforcement learning of dialogue policies, expressive conversational speech synthesis, and speech recognition. She has served on the organizing, senior, and program committees of many conferences and workshops. Her research work is funded by the National Science Foundation and the Army Research Office.

Lost City: Songs from a Changing Sea
Fri, Apr 21, 2017 @ 08:00 PM - 11:00 PM
Sonny Astani Department of Civil and Environmental Engineering
Receptions & Special Events
Rabbit Rabbit Radio will present a newly created song cycle inspired by the ocean and the changes it is undergoing due to climate change, overfishing, and pollution.
A free diver transcends her terrestrial ties and, through song, brings you on a tour of our oceans. Carried by the currents that connect us all, she encounters billions of bioluminescent creatures, the endlessly inventive structures of coral reefs on their annual night of spawning, fields of human detritus, and abandoned nets still fishing for no one. What she finds is at once awe-inspiring and devastating.
Crafted by veterans of rock, classical, and pop music, and using the most powerful aspects of each, Lost City is a set of songs that navigates a visceral tour through the worlds waterways. Each song frames an aspect of our evolving understanding of the ocean and our relationship to it. Created with the cooperation of the Woods Hole Oceanographic Institution, it is an abstract odyssey that reminds us of both the emotional and ecological significance the sea.
Conceived of by George Ban-Weiss, and composed by Carla Kihlstedt, Matthias Bossi, and Jeremy Flower. These four are joined in performance by Michael Abraham, Kristin Slipp, and Ariel Parkington.
