  • Publication number: 20040001063
    Abstract: Distribution displays for categories are provided which illuminate the distribution of continuous attributes over all cases in a category, and which provide a histogram of the population of the different states of categorical attributes. An array of such displays by attribute (in one dimension) and category (in another dimension) may be provided. Category diagram displays are also provided for visualizing the different categories, and their distributions, populations, and similarities. These are displayed through different shading of nodes and edges representing categories and the relationship between two categories, and through proximity of nodes.

  • Publication number: 20040002833
    Abstract: Systems and methods are provided for producing a mining model accuracy display that depicts the model's accuracy at predicting a state for a multiple-state variable. The model predicts a state and provides an associated probability for each case. Points are graphed such that one coordinate of the data point corresponds to a number N of cases and the other coordinate corresponds to the number of correct predictions made in the top N cases by probability.

  • Publication number: 20030236784
    Abstract: Systems and methods are provided for generating prediction queries to help a user build and execute prediction queries. A user interface (UI) is provided that is easy to use and understand in connection with the generation of a prediction query for data mining. The UI can be instantiated from a variety of disparate sources that may request query building services. While prediction queries and relational queries are quite different, the UI enables prediction queries to be built in a manner that is similar to the way relational queries are built. In one embodiment, the main screen of the UI includes four main components: (1) a table column mapping area, (3) a selection grid area, (4) a query text display area and (5) a query result grid area. In one embodiment, the query text display area and the query result grid area are initially not presented to the user.
