Visualization of music collections based on structural content similarity
(Fundação Getulio Vargas - FGVEscola de Matemática Aplicada - EMApIEEE Computer SocietyRio de Janeiro, 2014-08)
Users interact a lot with their personal music collections, typically using standard text-based interfaces that offer constrained functionalities based on assigned metadata or tags. Alternative visual interfaces have been ...
Combining diversity queries and visual mining to improve content-based image retrieval systems: the DiVI method
(Institute of Electrical and Electronics Engineers - IEEEMiami, 2015-12)
This paper proposes a new approach to improve similarity queries with diversity, the Diversity and Visually-Interactive method (DiVI), which employs Visual Data Mining techniques in Content-Based Image Retrieval (CBIR) ...
Evaluating boundary conditions and hierarchical visualization in CBIR
(Ieee Computer Soc, 2019-01-01)
Multiple descriptors are employed to represent images in Content-Based Image Retrieval (CBIR) systems. Each descriptor consists of a feature extractor associated with a distance function. An extractor is generally suitable ...
Visualizing the document pre-processing effects in text mining process
(2018-01-01)
Text mining is an important step to categorize textual data by using data mining techniques. As most obtained textual data is unstructured, it needs to be processed before applying mining algorithms – that process is known ...
Visual analytics of time-varying multivariate ionospheric scintillation data
(2017-11-01)
We present a clustering-based interactive approach to multivariate data analysis, motivated by the specific needs of scintillation data. Ionospheric scintillation is a rapid variation in the amplitude and/or phase of radio ...

El presente trabajo de investigación tiene como finalidad desarrollar el tema de Programación Visual.Net. Visual Basic. Net (VB.NET) es un lenguaje de programación orientado a objetos que se puede considerar una evolución ...
Least square projection: A fast high-precision multidimensional projection technique and its application to document mapping
(IEEE COMPUTER SOC, 2008)
The problem of projecting multidimensional data into lower dimensions has been pursued by many researchers due to its potential application to data analyses of various kinds. This paper presents a novel multidimensional ...
Estudio de los potenciales relacionados a eventos N170/VPP durante procesamiento visual de estímulos inducidos mediante imaginería mental versus alucinación hipnótica
(Universidad de Chile, 2015)
La hipnosis actualmente cuenta con vasta evidencia, tanto como estado
neurofisiológico, o como producto de sugestiones sobre la cognición y la conciencia. Entre sus
fenómenos asociados, se encuentran las alucinaciones ...
Hybrid visualization approach to show documents similarity and content in a single view
(2018-05-23)
Multidimensional projection techniques can be employed to project datasets from a higher to a lower dimensional space (e.g., 2D space). These techniques can be used to present the relationships of dataset instances based ...
Evaluation of approaches proposed to avoid overlap of markers in visualizations based on multidimensional projection techniques
(2019-01-01)
Multidimensional projection techniques provide graphical representations computed based on instance similarities to enable the analysis of abstract and possibly large data sets. However, when the data set size grows these ...
