Abstract: A user of a graphical visualization program controls what data is selectable through the program interface. Data for display may be grouped and assigned an opacity value. The opacity value may correspond to the number of data points within an n-dimensional grouping, a particular type or other grouping parameter. Two or more data groupings may overlap within the interface. The visualization program may set a threshold selectability level, for example based on user input. The input may be received based on an selection threshold slide bar within a graphical portion of the display. When a user selects a data grouping at a point where two or more data groupings overlap, the data groupings that satisfy the threshold selection level may be selected. Data groupings that do not satisfy the threshold selection level will not be selectable.

Abstract: An apparatus has an input configured to obtain various categories of naïve Bayes model data, and a formatter operatively coupled with the input. The formatter is configured to generate a format for displaying the naïve Bayes model data on a display device. The apparatus also has a displayer operatively coupled with the formatter. The displayer is configured to display the naïve Bayes model data in a two dimensional manner in the format on the display device. In addition, the displayer also is configured to display a navigation tool for maneuvering the displayed naïve Bayes model data on the display device when the displayed naïve Bayes model data is too wide to display on the display device.
