Speaker: Michael J. Carey, UC Irvine
Talk Title: AsterixDB: A Counter but Intuitive Approach to Big Data Management
Series: CS Seminar Series
Abstract: This lecture satisfies requirements for CSCI 591: Computer Science Research Colloquium
We are living in the Big Data era, and we are witnessing a shift in the role of data management system: Rather than "just" being the systems of record at the heart of traditional enterprises, modern Big Data management systems must model, capture, track, and react to the current state of the world. Doing so requires the ingestion of event data, arriving from a variety of devices, as well as enabling query access to the history of captured data over time. These requirements span a variety of scientific disciplines, including the handling of data produced by a variety sensors in health care, environmental monitoring applications, traffic monitoring, dynamic social network data, and many other domains.
AsterixDB is an open source Big Data Management System (BDMS) with a feature set that's very different than those of other platforms in today's Big Data ecosystem. The system was initially co-developed by UC Irvine and UC Riverside, starting in 2009 and leading eventually to its first beta release in mid-2013. It has recently moved to Apache, where AsterixDB is now an active incubating project. Many of the system's key design decisions relate to the aforementioned shift. This talk will first briefly review AsterixDB's data model, query language, and scale-out architecture. It will then examine a number of counter-cultural aspects of the AsterixDB system, including where its data lives, its runtime architecture, its approach to streaming data, its view of transactions, and its features for handling time-based data.
Biography: Michael J. Carey is a Bren Professor of Information and Computer Sciences at UC Irvine. Before joining UCI in 2008, Carey worked at BEA Systems for seven years and led the development of BEA's AquaLogic Data Services Platform product for virtual data integration. He also spent a dozen years teaching at the University of Wisconsin-Madison, five years at the IBM Almaden Research Center working on object-relational databases, and a year and a half at e-commerce platform startup Propel Software during the infamous 2000-2001 Internet bubble. Carey is an ACM Fellow, a member of the National Academy of Engineering, and a recipient of the ACM SIGMOD E.F. Codd Innovations Award. His current interests all center around data-intensive computing and scalable data management (a.k.a. Big Data). He was also an adjunct faculty member at USC for a few years during his BEA days, but that never earned him the USC season football tickets he'd been hoping for.

CS Colloquium: Geoffrey Zweig (Microsoft Research) - High Performance Image Captioning
Tue, Nov 03, 2015 @ 04:00 PM - 05:00 PM
Thomas Lord Department of Computer Science
Conferences, Lectures, & Seminars
Speaker: Geoffrey Zweig, Microsoft Research
Talk Title: High Performance Image Captioning
Series: CS Colloquium
Abstract: This lecture satisfies requirements for CSCI 591: Computer Science Research Colloquium
The problem of generating text conditioned on some sort of side information arises in many areas including dialog systems, machine translation, speech recognition, and image captioning. In this talk, we present a highly effective method for generating text conditioned on a set of words that should be mentioned. We apply this to the problem of image captioning by linking the generation module to a convolutional neural network that predicts a set of words that are descriptive of an image. The system placed first in the 2015 MSCoco competition on the Turing Test measure, and tied for first place overall.
This event will be available to stream HERE.

CS Student Colloquium: Chen Sun (USC) - Towards Large-scale Video Understanding
Tue, Nov 10, 2015 @ 04:00 PM - 05:15 PM
Thomas Lord Department of Computer Science
Conferences, Lectures, & Seminars
Speaker: Chen Sun, USC
Talk Title: Towards Large-scale Video Understanding
Series: CS Colloquium
Abstract: This lecture satisfies requirements for CSCI 591: Computer Science Research Colloquium
The ever-increasing popularity of video capturing devices and video sharing websites creates great opportunities for researchers to utilize the rich information encoded by consumer videos. Yet understanding videos on a large scale remains challenging: the video qualities usually vary in resolution, lighting condition and camera movement; spatiotemporal annotation of the videos could be expensive and time-consuming. As videos can be naturally represented by a hierarchy of events, activities and objects, it is essential to build a pool of mid-level concepts for semantic video interpretation. In light of these challenges, my research towards video understanding focuses on utilizing weak video-level annotations effectively, and building a stronger connection between language and vision. In this talk, I will show how Internet images can be used to localize fine-grained actions in videos without using temporal video annotations. I will then describe my approach to connect language and vision via visual concepts, and demonstrate how to automatically discover the visual concepts from parallel text and visual corpora.
Biography: Chen Sun is a Ph.D. candidate in the Computer Vision group at University of Southern California, advised by Prof. Ram Nevatia.

Speaker: Barna Saha, University of Massachusetts Amherst
Talk Title: Randomization in Data and Design
Series: CS Colloquium
Abstract:
This lecture satisfies requirements for CSCI 591: Computer Science Research Colloquium
Use of randomness is ubiquitous in modern computing, and promises to play a major role in today's Big Data era. There are three diverging viewpoints of how randomization impacts our ability to effectively understand and analyze data, (1) the underlying data itself may be stochastic, e.g. for the uncertainty in data acquisition; (2) randomization may appear by design to develop algorithms that are scalable; and (3) randomization can help answer why some simple heuristics are surprisingly effective on real data. In this talk, I will explain these phenomena through some basic tasks such as ranking, clustering and estimating distance or deviation of data from a formal (probabilistic) model.

CS Seminar: Dr. Gita Sukthankar (University of Central Florida) - Data-driven Social Informatics
Mon, Nov 30, 2015 @ 11:00 AM - 12:00 PM
Thomas Lord Department of Computer Science
Conferences, Lectures, & Seminars
Speaker: Gita Sukthankar, University of Central Florida
Talk Title: Data-driven Social Informatics
Series: Teamcore Seminar
Abstract: Data-driven social informatics unites models derived from social science with data-driven approaches in order to model and predict population behavior patterns. It can be used to advance our understanding of human behavior, guide public policy decisions, and improve user experience with social media platforms. In this talk, I'll describe work done at UCF's Intelligent Agents Lab (http://ial.eecs.ucf.edu/) in which we use a combination of agent-based modeling, machine learning, and crowdsourcing to model human social systems. The benefits of this approach will be illustrated using three case studies: 1) predicting the influence of social norms on smoking cessation behavior, 2) tracking campus parking usage using crowdsourcing and transportation modeling, 3) learning collaboration patterns from co-authorship networks. We believe that the combination of techniques yields a more nuanced view that relying on data alone.
