A Video Compression Case Study on a Reconfigurable VLIW Architecture
In this paper, we investigate the benefits of a flexible, application-specific instruction set by adding a run-time Reconfigurable Functional Unit (RFU) to a VLIW processor. Preli...

Machine Translation by Triangulation: Making Effective Use of Multi-Parallel Corpora
Current phrase-based SMT systems perform poorly when using small training sets. This is a consequence of unreliable translation estimates and low coverage over source and target p...
