Calibrating recurrent sliding window classifiers for sequential supervised learning

Creator:: Joshi, Saket Subhash
Abstract:: Sequential supervised learning problems involve assigning a class label to each item in a sequence. Examples include part-of-speech tagging and text-to-speech mapping. A very general-purpose strategy for solving such problems is to construct a recurrent sliding window (RSW) classifier, which maps some window of the input sequence plus some number...

Similarity-based real-time concurrency control protocols

Creator:: Lai, Chih
Abstract:: Serializability is unnecessarily strict for real-time systems because most transactions in such systems occur periodically and changes among data values over a few consecutive periods are often insignificant. Hence, data values produced within a short interval can be treated as if they are "similar" and interchangeable. This notion of similarity...

Towards architecture-adaptable parallel programming

Creator:: Kumaran, Santhosh
Abstract:: There is a software gap in parallel processing. The short lifespan and small installation base of parallel architectures have made it economically infeasible to develop platform-specific parallel programming environments that deliver performance and programmability. One obvious solution is to build architecture-independent programming environments. But the architecture independence usually comes at...

High-performance data-parallel input/output

Creator:: Moore, Jason Andrew
Abstract:: Existing parallel file systems are proving inadequate in two important arenas: programmability and performance. Both of these inadequacies can largely be traced to the fact that nearly all parallel file systems evolved from Unix and rely on a Unix-oriented, single-stream, block-at-a-time approach to file I/O. This one-size-fits-all approach to parallel...
