- Modified Logistic Regression: An Approximation to SVM and Its Applications in Large-Scale Text Categorization
- Logistic Regression LR has been widely used in statistics for many years, and has received extensive study in machine learning community recently due to its close relations to Support Vector Machines SVM and Ad-a-Boost. This paper uses a modified version of LR to approximate the optimization of SVM by a...

- Buy-at-Bulk Network Design With Protection
- This paper considers approximation algorithms for buy-at-bulk network design, with the additional constraint that demand pairs be protected against edge or node failures in the network. In practice, the most popular model used in high speed telecommunication networks for protection against failures, is the so-called 1+1 model. In this model,...

- Hierarchical Placement and Network Design Problems
- This paper gives the first constant-approximations for a number of layered network design problems. It begins by modeling hierarchical caching, where caches are placed in layers and each layer satisfies a fixed percentage of the demand bounded miss rates. The paper presents a constant approximation to the minimum total cost...
