Computer Science/Discrete Mathematics Seminar II

Derandomizing BPL?
10:30am|S-101

I will survey some of the basic approaches to derandomizing Probabilistic Logspace computations, including the "classical" Nisan, Impagliazzo-Nisan-Widgerson and Reingold-Raz generators, the Saks-Zhou algorithm and some more recent approaches. We'll...

Collective Phenomena, Collective Motion, and Collective Action in Ecological Systems
2:00pm|S-101

Fundamental questions in basic and applied ecology alike involve complex adaptive systems, in which localized interactions among individual agents give rise to emergent patterns that feed back to affect individual behavior. In such systems, a...

Computer Science/Discrete Mathematics Seminar I

Polar Codes and Randomness Extraction for Structured Sources
11:15am|S-101

Polar codes have recently emerged as a new class of low-complexity codes achieving Shannon capacity. This talk introduces polar codes with emphasis on the probabilistic phenomenon underlying the code construction. New results and connections to...
