    • ChatKG: Visualizing Temporal Patterns as Knowledge Graph 

      Christino, Leonardo; Paulovich, Fernando V. (The Eurographics Association, 2023)
      Line-chart visualizations of temporal data enable users to identify interesting patterns for the user to inquire about. Using oracles, such as chat AIs, Visual Analytic tools can automatically uncover explicit knowledge ...

    • A Generic Model for Projection Alignment Applied to Neural Network Visualization 

      Cantareira, Gabriel Dias; Paulovich, Fernando V. (The Eurographics Association, 2020)
      Dimensionality reduction techniques are popular tools for the visualization of neural network models due to their ability to display hidden layer activations and aiding the understanding of how abstract representations are ...

    • Nonparametric Dimensionality Reduction Quality Assessment based on Sortedness of Unrestricted Neighborhood 

      Pereira-Santos, Davi; Neves, Tácito Trindade Araújo Tiburtino; Carvalho, André C. P. L. F. de; Paulovich, Fernando V. (The Eurographics Association, 2023)
      High-dimensional data are known to be challenging to explore visually. Dimensionality Reduction (DR) techniques are good options for making high-dimensional data sets more interpretable and computationally tractable. An ...

    • Progressive Multidimensional Projections: A Process Model based on Vector Quantization 

      Ventocilla, Elio Alejandro; Martins, Rafael M.; Paulovich, Fernando V.; Riveiro, Maria (The Eurographics Association, 2020)
      As large datasets become more common, so becomes the necessity for exploratory approaches that allow iterative, trial-anderror analysis. Without such solutions, hypothesis testing and exploratory data analysis may become ...
