Talk Title: Large-Scale Secure Computation
Series: CS Colloquium
Abstract: The ability to collect and process large data sets has unlocked exciting new technological and research discoveries. Unfortunately, in several important applications, it is not possible to leverage the full extent of collected data, when information consists of sensitive data sets held by individual agents who are either unable or unwilling to share the data itself (e.g., patients' medical information gathered by different medical studies).
A promising approach to enable data sharing within these scenarios is to make use of cryptographic tools such as secure multi-party computation (MPC). MPC protocols provide a means for mutually untrusting parties to jointly evaluate a global function f over their secret inputs, while guaranteeing that no information is revealed beyond the function output.
However, despite great progress in MPC techniques in the last three decades, the surrounding world of data aggregation and computation has leapt even more rapidly forward. For example, nearly all existing MPC protocols require each party to store information comparable to the {\em total} combined data, and evaluate the desired function via a {\em boolean circuit} representation. When the number of parties and size of data is large, or when the functions to be computed are "lightweight" (e.g. touching only small portions of the data), these limitations completely obliterate feasibility of MPC as a solution.
In this talk, I will introduce a new class of techniques yielding MPC protocols whose parameters scale to the modern regime of massive data.
Lecture will be available to stream HERE.

Talk Title: COMPUTATIONAL ELECTROMAGNETICS AND ITS APPLICATIONS FROM DC TO OPTICS
Abstract: Due to the pervasive use of computing powers, computational electromagnetics (CEM) has become an indispensable technology for maintaining Mooreâs law in semiconductor industries, engineering new electromagnetic and optical materials, characterizing the next generation nano devices, and accelerating future communication systems. Facing surging scientific and engineering demands, the complexity of physics in todayâs CEM researches is unprecedented. Because of close connections between electromagnetics and optics, CEM generates essential methodologies and insights to new advances from static circuits, microwave systems, to THz and optical devices.
There are several primary challenges that CEM is facing: complex environments, extreme frequencies, and multidisciplines. The first two are heavily referenced and employed by the last one for advances in optoelectronics and nano scale devices. By developing physical models and numerical engines, I have been addressing above issues with novel solutions. New integral equation methods in the frequency domain and discontinuous Galerkinâs methods in the time domain have been proposed by us to characterize problems that are homogeneous or inhomogeneous, linear or nonlinear, isotropic or anisotropic, deterministic or stochastic, etc. The numerical fast multipole algorithms and other divide and conquer strategies rooted from physical principles are employed to organize numerical solutions. At the low frequency, the decoupling of electronic and magnetic fields is employed to establish a stable system. For the broadband request, both evanescent and propagating properties are integrated to support a smooth transition from the circuit physics to wave physics. By further pushing up the frequency, novel computational solutions for optoelectronic devices and graphene have been successfully developed to characterize the electromagnetic field with them. By demonstrating computational solutions ranging from DC, microwave, THz, to optical applications, the talk will conclude with future research discussions.

Dynamics and control of distributed systems
Tue, Mar 10, 2015 @ 10:00 AM - 11:00 AM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Mihailo Jovanovic, University of Minnesota
Talk Title: Dynamics and control of distributed systems
Abstract: In the first part of the talk, we examine fundamental limitations arising from the use of local feedback in networks subject to stochastic disturbances. For vehicular formation control problems in topology of regular lattices we show that it is impossible to have coherent large formations, that behave like rigid lattices, in one and two spatial dimensions. Yet we prove that this is achievable in 3D. The observed phenomenon is a consequence of the fact that, in 1D and 2D, local feedback laws are ineffective in guarding against disturbances with large spatial wavelength. We provide connections with several other problems including distributed averaging algorithms, global mean first passage time of random walks, effective resistance in electrical networks, and statistical mechanics of harmonic solids. We close the first part of the talk by demonstrating how tools and ideas from control theory, optimization, and compressive sensing can be combined to identify network topologies that strike desired tradeoff between the performance and sparsity.
In the second part of the talk, techniques from control theory are used to study the early stages of transition to turbulence in wall-bounded shear flows. We demonstrate high sensitivity of the flow equations to modeling imperfections and show that control theory can be used not only to design flow control algorithms but also to provide valuable insights into the transition mechanisms.

Talk Title: Meta-Information Visualization: A Human Factors Approach
Abstract: In many domains, users are confronted with large volumes of information from a variety of sources. In addition to understanding the content of the information, they need to understand and reason about potential qualifiers of the information. These qualifiers, or meta-information, include characteristics such as the uncertainty associated with the data, the age of the data, and the source of the data. There is a long history of research in scientific visualization and geospatial information systems which has considered visual techniques for representing complex information, in both spatial and non-spatial frames of reference. Our own research has considered how visual techniques such as pixilation, transparency, saturation, and texture can be used to represent a variety of meta-information categories. This talk will survey results from a number of empirical studies which have examined how people interpret meta-information visualization regarding geospatial regions and objects, how different visualizations impact decision-making and task performance, and how these measure are affected by type of meta-information, task demands, and visual context.
