In long adaptive optics corrected exposures, exoplanet detections are currently limited by speckle noise originating from the telescope and instrument optics, and it is expected that such noise will also limit future high-contrast imaging instruments for both ground and space-based telescopes. Previous theoretical analysis have shown that the time intensity variations of a single speckle follow...

In neural interactive translation prediction, a system provides translation suggestions (“auto-complete” functionality) for human translators. These translation suggestions may be rejected by the translator in predictable ways; being able to estimate confidence in the quality of translation suggestions could be useful in providing additional information for users of the system. We show that a v...

This paper describes the development of a word-level confidence metric suitable for use in a dialog system. Two aspects of the problems are investigated: the identification of useful features and the selection of an effective classifier. We find that two parse-level features, Parsing-Mode and SlotBackoff-Mode, provide annotation accuracy comparable to that observed for decoder-level features. H...

Multi-level simultaneous component analysis (MLSCA) was designed for the exploratory analysis of hierarchically ordered data. MLSCA specifies a component model for each level in the data, where appropriate constraints express possible similarities between groups of objects at a certain level, yielding four MLSCA variants. The present paper discusses different bootstrap strategies for estimating...

In any dialogue manager, confidence scores play a central role in ensuring robust operation. Recently, dialogue managers have attempted to exploit N-best lists of alternatives for the semantics rather than the single most likely interpretation. Each alternative in the N-best list must have an associated confidence score and it is very useful to be able to evaluate the utility of these scored li...

Increasing soft error rates for semiconductor devices manufactured in later technologies enforces the use of fault tolerant techniques such as Roll-back Recovery with Checkpointing (RRC). However, RRC introduces time overhead that increases the completion (execution) time. For nonreal-time systems, research have focused on optimizing RRC and shown that it is possible to find the optimal number ...
