Compressed Data Structures: Dictionaries and Data-Aware Measures
Abstract. We propose measures for compressed data structures, in which space usage is measured in a data-aware manner. In particular, we consider the fundamental dictionary problem...

Rate-Based versus Distortion-Based Optimal Joint Source-Channel Coding
- We consider a joint source-channel coding system that protects an embedded wavelet bitstream against noise using a finite family of channel codes with error detection and error c...

Coresets and Sketches for High Dimensional Subspace Approximation Problems
We consider the problem of approximating a set P of n points in Rd by a j-dimensional subspace under the p measure, in which we wish to minimize the sum of p distances from each p...

Density gradient minimization with coupling-constrained dummy fill for CMP control
In the nanometer IC design, dummy fill is often performed to improve layout pattern uniformity and the post-CMP quality. However, filling dummies might greatly increase intercon...

Sharp Separation and Applications to Exact and Parameterized Algorithms
Many divide-and-conquer algorithms employ the fact that the vertex set of a graph of bounded treewidth can be separated in two roughly balanced subsets by removing a small subset o...
