High Dimensional Similarity Joins: Algorithms and Performance Evaluation

Current data repositories include a variety of data types, including audio, images, and time series. State-of-the-art techniques for indexing such data and doing query processing rely on a transformation of data elements into points in a ...

Efficient Cost Models for Spatial Queries Using R-Trees

Selection and join queries are fundamental operations in Data Base Management Systems (DBMS). Support for nontraditional data, including spatial objects, in an efficient manner is of ongoing interest in database research. Toward this goal, access ...

The Effect of Buffering on the Performance of R-Trees

Past R-tree studies have focused on the number of nodes visited as a metric of query performance. Since database systems usually include a buffering mechanism, we propose that the number of disk accesses is a more realistic measure of performance. We ...

Indexing the Solution Space: A New Technique for Nearest Neighbor Search in High-Dimensional Space

Similarity search in multimedia databases requires an efficient support of nearest-neighbor search on a large set of high-dimensional points as a basic operation for query processing. As recent theoretical results show, state of the art approaches to ...

Sync Classes: A Framework for Optimal Scheduling of Requests in Multimedia Storage Servers

There have been many proposals on how media-on-demand servers can effectively allow clients to share resources. In this paper, given a set of clients, we show how these clients may be partitioned into sync-classes sets of clients who can be serviced ...

Dynamically Negotiated Resource Management for Data Intensive Application Suites

In contemporary computers and networks of computers, various application domains are making increasing demands on the system to move data from one place to another, particularly under some form of soft real-time constraint. A brute force technique for ...

MPGS: An Interactive Tool for the Specification and Generation of Multimedia Presentations

Multimedia presentations are composed of objects belonging to different data types such as video, audio, text, and image. An important aspect is that, quite often, the user defining a presentation needs to express sophisticated temporal and spatial ...

Natural Language Grammatical Inference with Recurrent Neural Networks

This paper examines the inductive inference of a complex grammar with neural networks specifically, the task considered is that of training a network to classify natural language sentences as grammatical or ungrammatical, thereby exhibiting the same ...
