A Stable Algorithm for Multi-dimensional Padé Systems and the Inversion of Generalized Sylvester MatricesDownload
Technical report TR94-07. For k+1 power series a_0(z), ..., a_k(z), we present a new iterative, look-ahead algorithm for numerically computing Pade'-Hermite systems and simultaneous Pade' systems along a diagonal of the associated Pade' tables. The algorithm computes the systems at all those...
A Study of Image Indexing Techniques for Multimedia Database Systems
Technical report TR95-19. The role of indexing in query optimization is well-understood in the database community. Indexes enable efficient access to a subset of a database. There have been many studies on indexing within the context of relational database management systems (RDBMS). The most...
Technical report TR95-23. Multiple threads can be used not only as a mechanism for tolerating unpredictable communication latency but also for facilitating dynamic scheduling and load balancing. Multithreaded systems are well suited to highly irregular and dynamic applications, such as tree...
We present a distribution-based and transformation-based approach to synthetic data generation and demonstrate that the approach is very efficient in generating different types of multi-dimensional numerical datasets for data clustering and outlier analysis. We developed a data generating system...
Technical report TR94-10. In recent years, numerous new backtracking algorithms have been proposed. The algorithms are usually evaluated by empirical testing. This method, however, has its limitations. Our thesis adopts a different, purely theoretical approach, which is based on...
Technical report TR97-04. Genetic algorithms (GAs) are probabilistic search algorithms that are loosely based on biological evolution. Analyzing genetic algorithms has proven difficult, for a variety of reasons, but a landscape paradigm that rigorously models the search of GAs has become...
Technical report TR06-07. The development of the Ignorant Value Assessment Tool (DIVAT) for two-player Limit Texas Hold'em is discussed in detail. The tool is then applied to several poker matches to obtain a statistically unbiased reduced-variance analysis of skill differences. Please note:...
Technical report TR96-11. We propose a transactional activity model (TAM) for specification and management of open-ended cooperative activities. TAM is a careful combination of an activity composition model with extended transaction models such as split/join transactions. In contrast to each of...
A Unified Framework for Searching Multiple Compressed Collections
Technical report TR01-17. In this work, we propose a new framework for searching directly through multiple compressed collections. We combine, in a single framework, four techniques for efficient, low-overhead text retrieval: inverted index compression, block addressing, sequential searching in...
Technical report TR95-13. In this work, we present a uniform behavioral temporal object model which includes a rich and extensible set of types and behaviors to support various notions of time. Our temporal model supports the continuous and discrete domains of time. It also supports various...
