  • CS Colloquium: Theodoros Rekatsinas (Stanford University) - Data Integration with Unreliable Sources

    Wed, Feb 15, 2017 @ 11:00 AM - 12:20 PM

    Computer Science

    Conferences, Lectures, & Seminars


    Speaker: Theodoros Rekatsinas, Stanford University

    Talk Title: Data Integration with Unreliable Sources

    Series: CS Colloquium

    Abstract: This lecture satisfies requirements for CSCI 591: Computer Science Research Colloquium.

    Data integration is an essential element of data-intensive science and modern analytics. Users often need to combine data from different sources to gain new scientific knowledge, obtain accurate insights, and create new services. However, today's upsurge in the number and heterogeneity-”in terms of format and reliability-”of data sources limits the ability of users to reason about the value of data. This raises the fundamental questions: what makes a data source useful to end users, how can we integrate unreliable data, and which sources we need to combine to maximize the user's utility?

    In this talk, I discuss how to assess and leverage the quality and reliability of data to make data integration more efficient. Specifically, I demonstrate how statistical learning is the key to managing large volumes of heterogeneous sources effectively. Building upon this observation, I introduce new solutions to classical data integration problems, such as data conflict resolution and data cleaning, and show that these solutions outperform their traditional counterparts by large margins. I finish with an outlook on how recent advancements in machine learning have the potential to streamline the construction of end-to-end data curation systems and bring data closer to users.

    Biography: Theodoros (Theo) Rekatsinas is a Moore Data Postdoctoral Fellow at Stanford working with Christopher Ré; he earned his Ph.D. in Computer Science from the University of Maryland, where he was advised by Amol Deshpande and Lise Getoor. His research interests are in data management, with a focus on data integration, data cleaning, and uncertain data. Theo's work on using quality-aware data integration techniques to forecast the emergence and progression of disease outbreaks received the Best Paper Award at SDM 2015. Theo was awarded the Larry S. Davis Doctoral Dissertation award in 2015.

    Talk Title: Delays in biological networks and feedback design

    Series: CommNetS

    Abstract: Gene regulatory networks lie at the crux of life and, despite rapidly evolving tools in synthetic biology, our ability to replicate the robustness of these systems remains a challenge. We have not been able to fully understand and, hence, design effective feedback mechanisms. I present work towards said challenge through extensions in control and dynamical systems lending to an effective network design in the presence of delays, an adversarial facet of biology.

    In this talk I focus on the role of delays in biological networks. I show how understanding the effects of delays and stochastic processes on gene expression dynamics can be used to design effective controllers for stability. First, I present a stability condition for stochastic linear systems with identically, independently, distributed stochastic delays. In an application to a single gene oscillator, I demonstrate the stabilizing effects of increasing the relative variance of the delay uncertainty. Using the insight gained from this analysis along with inspiration from nature, I present a stabilizing controller for the single gene oscillator based on adding a larger delay in parallel. A generalized delay-based feedback design approach shows this architecture to be near optimal. In summary, through a deeper understanding of the effects of delays on dynamics, I arrive at an effective stabilizing controller in a system with large delays, where traditional methods in controls cannot be used for feedback design.


    Biography: Marcella M. Gomez is currently a postdoctoral fellow at the University of California, Berkeley in Electrical Engineering and Computer Science. She received her bachelors from UC Berkeley in 2008 and her PhD from the California Institute of Technology in 2015, both in Mechanical Engineering. Her research interests lie in developing synergistic methods combining control and dynamical systems with synthetic biology for the advancement in understanding and designing of complex genetic networks.
