PREDICTIVE FUSION CODING OF SPATIO-TEMPORALLY CORRELATED SOURCES

by Sharad Ramaswamy, Kenneth Rose
"... This paper considers the problem of predictive fusion coding for storage of multiple spatio-temporally correlated sources so as to en-able efficient selective retrieval of data from subsets of sources as designated by future queries. Only statistical information about fu-ture queries is available du ..."

Sampling Trajectory Streams with Spatiotemporal Criteria

by Michalis Potamias, Kostas Patroumpas, Timos Sellis - Proceedings of SSDBM , 2006
"... Monitoring movement of high-dimensional points is essential for environmental databases, geospatial applications, and biodiversity informatics as it reveals crucial information about data evolution, provenance detection, pattern matching etc. Despite recent research interest on processing continuous ..."

continuous queries in the context of spatiotemporal data streams, the main focus is on managing the current location of numerous moving objects. In this paper, we turn our attention onto a historical perspective of movement and examine trajectories generated by streaming positional updates. The key challenge

TENSOR-BASED MULTIPLE OBJECT TRAJECTORY INDEXING AND RETRIEVAL

by Xiang Ma, Faisal I. Bashir, Ashfaq A. Khokhar, Dan Schonfeld
"... This paper presents novel tensor-based object trajectory modelling techniques for simultaneous representation of multiple objects motion trajectories in a content based indexing and retrieval framework. Three different tensor decomposition techniques-PARAFAC, HOSVD and Multiple-SVD-are explored to a ..."

SeTraStream: Semantic-Aware Trajectory Construction over Streaming Movement Data

by Zhixian Yan, Nikos Giatrakos, Vangelis Katsikaros, Nikos Pelekis, Yannis Theodoridis
"... Abstract. Location data generated from GPS equipped moving objects are typically collected as streams of spatiotemporal 〈x, y, t 〉 points that when put together form corresponding trajectories. Most existing studies focus on building ad-hoc querying, analysis, as well as data mining techniques on fo ..."

Author manuscript, published in "ICDT (2012) 46-60" Highly Expressive Query Languages for Unordered Data Trees ∗

by Serge Abiteboul, Pierre Bourhis, Victor Vianu , 2012
"... We study highly expressive query languages for unordered data trees, using as formal vehicles Active XML and extensions of languages in the while family. All languages may be seen as adding some form of control on top of a set of basic pattern queries. The results highlight the impact and interplay ..."

Large scale Bayesian inference and experimental design for sparse linear models

by Matthias W. Seeger, Hannes Nickisch - Journal of Physics: Conference Series
"... Abstract. Many problems of low-level computer vision and image processing, such as denoising, deconvolution, tomographic reconstruction or superresolution, can be addressed by maximizing the posterior distribution of a sparse linear model (SLM). We show how higher-order Bayesian decision-making prob ..."
Abstract - Cited by 22 (2 self) - Add to MetaCart
-making problems, such as optimizing image acquisition in magnetic resonance scanners, can be addressed by querying the SLM posterior covariance, unrelated to the density’s mode. We propose a scalable algorithmic framework, with which SLM posteriors over full, high-resolution images can be approximated

The PRISM/PRISM++ approach consists in providing the users with a set of SQL-based Schema Modification Opera-tors (SMOs), which describe how the tables in the old schema are modified into those in the new schema.

by Zhongqiang Chen, Yuan Zhang, Zhongrong Chen, Alex Delis , 2008
"... Intrusion detection/prevention systems (IDSs/IPSs) heavily rely on signature databases and pattern matching (PM) techniques to identify network attacks. The engines of such systems often employ traditional PM algorithms to search for telltale patterns in network flows. The observations that real-wor ..."

In its querying phase, the framework quickly identifies attack-free connections by transforming input traffic into its fingerprint space and matching its digest against those of attack signatures.
