Predicting the direction of conditional branches with high accuracy has become critical to the success of new deeper and wider processor pipelines. However, choosing a branch predictor is hard because the best choice is workload-dependent. Meta(or Hybrid-) predictors provide a rudimentary FSA-based heuristic for choosing between two predictors on-line. Such approaches have little or no theoreti...

Sites participating in the recent message understanding conferences have increasingly focused their research on developing methods for automated knowledge acquisition and tools for human-assisted knowledge engineering. However, it is important to remember that the ultimate users of these tools will be domain experts, not natural language processing researchers. Domain experls have extensive kno...

Probabilistic algorithms o er a means of computing that works with the grain of analogue hardware, rather than against it. This paper proposes the use of such an algorithm in applications where the advantages of analogue hardware are most likely to be realised.
