Counter Braids: Asymptotic Optimality of the Message Passing Decoding Algorithm
Counter structure braids high-speed link counter braid
2015/8/21
A novel counter architecture, called Counter Braids, has recently been proposed for per-flow counting on high-speed links. Counter Braids has a layered structure and compresses the flow si...
Recovering Edges in Ill-Posed Inverse Problems:Optimality of Curvelet Frames

We consider a model problem of recovering a function f(x1, x2) from noisy Radon data. The function f to be recovered is assumed smooth apart from a discontinuity along a C2 curve – i.e. an edge. We us...
Sonority variation in Stochastic Optimality Theory: Implications for markedness hierarchies
Sonority variation Stochastic Optimality Theory
2014/4/25
Constraints based on the sonority scale and other markedness hierarchies have been formalized
in two different ways: as scale-partition constraint families, with a universally fixed ranking, and
as...
