  Data Reduction Techniques for Simulation, Visualization and Data ...

  Abstract Data reduction is increasingly being applied to scientific data for numerical simulations, scientific visualizations and data analyses. It is most often used to lower I/O and storage costs, and sometimes to lower in-memory data size as well. With this paper, we consider five categories of data reduction techniques based on their information loss: (1) …

  Wavelet Transforms in Data Mining - GeeksforGeeks

  2022314 · The discrete wavelet transform (DWT) is a signal processing technique that transforms linear signals. The data vector X is transformed into a numerically different vector, Xo, of wavelet coefficients when the DWT is applied. The two vectors X and Xo must be of the same length. When applying this technique to data reduction, we consider n ...
