Visualization in Big Data: a tool for pattern recognition in data stream
(Revista de Sistemas de Informação da FSMA, 2019)
Obtenção de padrões sequenciais em data streams atendendo requisitos do Big Data
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ciência da Computação - PPGCCCâmpus São Carlos, 2016-06-06)
The growing amount of data produced daily, by both businesses and individuals in the web, increased the demand for analysis and extraction of knowledge of this data. While the last two decades the solution was to store and ...
TS-stream: clustering time series on data streams
(SpringerDordrecht, 2014-06)
The current ability to produce massive amounts of data and the impossibility in storing it motivated the development of data stream mining strategies. Despite the proposal of many techniques, this research area still lacks ...
Proposal of a new stability concept to detect changes in unsupervised data streams
(Pergamon-ElsevierOxford, 2014-11-15)
Learning from continuous streams of data has been receiving an increasingly attention in the last years. Among the many challenges related to mining data streams, change detection is one topic frequently addressed. Being ...
A stable and online approach to detect concept drift in data streams
(Universidade de São Paulo - USPUniversidade Federal de São Carlos - UFSCarCentro de Robótica de São Carlos - CROBSociedade Brasileira de Computação - SBCSociedade Brasileira de Automática - SBASão Carlos, 2014-10)
The detection of concept drift allows to point out when a data stream changes its behavior over time, what supports further analysis to understand why the phenomenon represented by such data has changed. Nowadays, researchers ...
’HALITE IND. DS’: fast and scalable subspace clustering for multidimensional data streams
(Society for Industrial and Applied Mathematics - SIAMMiami, 2016-05)
Given a data stream with many attributes and high frequency of events, how to cluster similar events? Can it be done in real time? For example, how to cluster decades of frequent measurements of tens of climatic attributes ...
Unsupervised density-based behavior change detection in data streams
(IOS PressAmsterdam, 2014)
The ability to detect changes in the data distribution is an important issue in Data Stream mining. Detecting changes in data distribution allows the adaptation of a previously learned model to accommodate the most recent ...
Evaluation of multiclass novelty detection algorithms for data streams
(IEEELos Alamitos, 2015-11)
Data stream mining is an emergent research area that investigates knowledge extraction from large amounts of continuously generated data, produced by non-stationary distribution. Novelty detection, the ability to identify ...
