Technical Perspective: Strange Effects in High Dimension
In studying the genetic basis of a disease, it is now common to select a set of relevant genes G, and to measure how strongly they are expressed in cell samples from a group…

Technical Perspective: Want to Be a Bug Buster?
Microprocessor performance has increased exponentially. These chips with ever increasing complexity are not always fully functional on the first attempt, they need to be debugged…

Post-Silicon Bug Localization For Processors Using IFRA
IFRA overcomes major challenges associated with a very expensive step in post-silicon validation of processors — pinpointing a bug location and the instruction sequence that exposes the bug from a system failure, such as a crash…

Faster Dimension Reduction
Data represented geometrically in high-dimensional vector spaces can be found in many applications. The need to manipulate such data in huge corpora and to support various query types gives rise to the question of how to represent…
