  • Presentation Title: Compressive Sensing

    Abstract
    Compressive sensing is a new sampling/data acquisition theory based on the discovery that one can exploit sparsity or compressibility when acquiring signals of general interest, and that one can design nonadaptive sampling techniques that condense the information in a compressible signal into a small amount of data. Interestingly, this may be changing the way engineers think about signal acquisition in areas ranging from analog-to-digital conversion, digital optics, magnetic resonance imaging, and seismics. This talk will introduce fundamental conceptual ideas underlying this new sampling or sensing theory. There are already many ongoing efforts to build a new generation of sensing devices based on compressive sensing, and we will address remarkable recent progress in this area as well.

2007图灵奖获得者

  • Edmund M. Clarke received a B.A. degree in mathematics from the University of Virginia, Charlottesville, VA, in 1967, an M.A. degree in mathematics from Duke University, Durham NC, in 1968, and a Ph.D. degree in Computer Science from Cornell University, Ithaca NY, in 1976. After receiving his Ph.D., he taught in the Department of Computer Science, Duke University, for two years. In 1978 he moved to Harvard University, Cambridge, MA where he was an Assistant Professor of Computer Science in the Division of Applied Sciences. He left Harvard in 1982 to join the faculty in the Computer Science Department at Carnegie-Mellon University, Pittsburgh, PA. He was appointed Full Professor in 1989. In 1995 he became the first recipient of the FORE Systems Professorship, an endowed chair in the School of Computer Science. He was named a University Professor in 2008.

    Dr. Clarke’s interests include software and hardware verification and automatic theorem proving. In his Ph.D. thesis he proved that certain programming language control structures did not have good Hoare style proof systems. In 1981 he and his Ph.D. student Allen Emerson first proposed the use of Model Checking as a verification technique for finite state concurrent systems. His research group pioneered the use of Model Checking for hardware verification. Symbolic Model Checking using BDDs was also developed by his group. This important technique was the subject of Kenneth McMillan’s Ph.D. thesis, which received an ACM Doctoral Dissertation Award. In addition, his resarch group developed the first parallel resolution theorem prover (Parthenon) and the first theorem prover to be based on a symbolic computation system (Analytica).

    Dr. Clarke has served on the editorial boards of Distributed Computing, Logic and Computation, and IEEE Transactions in Software Engineering. He is the former editor-in-chief of Formal Methods in Systems Design. He is on the organizing committee of Logic in Computer Science (LICS) and on the steering committee of  Computer-Aided Verification (CAV). He received a Technical Excellence Award with Randy Bryant and Ken McMillan from the Semiconductor Research Corporation in 1995 for his work on formal verification techniques. He was a co-winner with Randy Bryant, Allen Emerson, and Kenneth McMillan of the ACM Kanellakis Award in 1998 for the development of Symbolic Model Checking.  In 1999 he received an Allen Newell Award for Excellence in Research from the Carnegie Mellon Computer Science Department.  In 2004 he received the IEEE Harry H. Goode Memorial Award for significant and pioneering contributions to formal verification of hardware and software systems, and for the profound impact these contributions have had on the electronics industry.  He was elected to the National Academy of Engineering in 2005 for contributions to the formal verification of hardware and software correctness.  He was a recipient with Allen Emerson and Joseph Sifakis of the 2007 ACM Turing Award for his role in developing Model Checking into a highly effective verification technology, widely adopted in the hardware and software industries.  In 2008 he received the CADE Herbrand Award for Distinguished Contributions to Automated Reasoning in recognition of his role in the invention of Model Checking and his sustained leadership in the area for more than two decades. In 2011 he was elected to the American Academy of Arts & Sciences which includes distinguished leaders in the sciences, social sciences, the humanities, the arts, as well as business and public affairs. Dr. Clarke is a Fellow of the ACM and the IEEE, and a member of Sigma Xi and Phi Beta Kappa.

  • Presentation Title: Model Checking and the Curse of Dimensionality

    Abstract
    The term «Curse of Dimensionality» was coined by the famous mathematician, Richard Bellman.  He used the term to describe the exponential increase in volume associated with adding extra dimensions to an object in space.  One implication of the Curse of Dimensionality is that methods for numerical solution of various optimization problems require vastly more computer time when the number of state variables involved increases.  A similar phenomenon occurs in temporal logic model checking.  Model checking is an automatic verification technique for concurrent systems that are finite state or have finite state abstractions.  It has been used successfully to verify computer hardware and is beginning to be used to verify computer software as well. As the number of processes in the system increases, the number of global system states grows exponentially.  This is called the state explosion problem. Much of the research in model checking over the past 30 years has involved developing techniques for dealing with this problem.  In this talk I will describe some recent approaches to the state explosion problem using compositional reasoning, abstract interpretation, and statistical sampling techniques.  I will give examples about how these techniques can be used to make model checking feasible for computer software and to understand molecular processes in systems biology.

  • Presentation Title: Solution Concepts for the 21st Century

    Abstract
    Nash equilibrium is the most commonly-used notion of equilibrium in game theory.  However, it suffers from numerous problems.  Some are well known in the game theory community; for example, the Nash equilibrium of repeated prisoner’s dilemma is neither normatively nor descriptively reasonable. However, new problems arise when considering Nash equilibrium from a computer science perspective: for example, Nash equilibrium is not robust (it does not tolerate «faulty» or «unexpected» behavior), it does not deal with coalitions, it does not take computation cost into account, and it does not deal with cases where players are not aware of all aspects of the game.  In this talk, I discuss solution concepts that try to address these shortcomings of Nash equilibrium.  This talk represents joint work with various collaborators, including Ittai Abraham, Danny Dolev, Rica Gonen, Rafael Pass, and Leandro Rego.  No background in game theory will be presumed.
