Abstract

The need to analyze large amounts of multivariate data raises the fundamental problem of dimensionality reduction which is defined as a process of mapping data from high-dimensional space into low-dimensional. One of the most popular methods for handling this problem is multidimensional scaling. Due to the technological advances, the dimensionality of the input data as well as the amount of processed data is increasing steadily but the requirement of processing these data within a reasonable time frame still remains an open problem. Recent development in graphics hardware allows to perform generic parallel computations on powerful hardware and provides an opportunity to solve many time-constrained problems in both graphical and non-graphical domain. The purpose of this survey is to describe and analyze recent implementations of multidimensional scaling algorithms on graphics processing units and present the applicability of these algorithms on such architectures based on the experimental results which show a decrease of execution time for multi-level approaches.

Digging out implicit semantics from user interaction

Authors: Stéphane Marchand-Maillet

Published in: Dagstuhl Seminar Proceedings, Volume 8251, Contextual and Social Media Understanding and Usage (2009)

Abstract

User interaction may take many forms in multimedia systems. Current systems mainly waste this implicit and natural source of semantic knowledge and rather create tedious and unnatural interaction protocols. We advocate for a complete integration of natural interaction protocols and semantic knowledge capture, mainly thru mining interaction sessions. We assert that users possess the ability to quickly examine and summarise these documents, even subconsciously. Examples include specifying relevance between a query and results, rating preferences in film databases, purchasing items from online retailers, and even simply browsing web sites. Data from these interactions, captured and stored in log files, can be interpreted to have semantic meaning, which proves indispensable when used in a collaborative setting where users share similar preferences and goals.
