ROSETTA manufacturer description

ROSETTA 1.00 is a toolkit for analyzing tabular data within the framework of rough set theory. ROSETTA Charts is designed to support the overall data mining and knowledge discovery process: From initial browsing and preprocessing of the data, via computation of minimal attribute sets and generation of if-then rules or descriptive patterns, to validation and analysis of the induced rules or patterns.
ROSETTA download is intended as a general-purpose tool for discernibility-based modelling, and is not geared specifically towards any particular application domain.
ROSETTA offers a highly intuitive GUI environment where data-navigational abilities are emphasized. The GUI is highly object-oriented in that all manipulable objects are represented as individual GUI items, each with their own set of context-sensitive menus.
Some features currently offered by the computational kernel include:

  • Import/export

    • Partial integration with DBMSs via ODBC.

    • Exporting of rules, reducts, tables, graphs and other objects to various formats, including XML, C++ and Prolog.

  • Preprocessing

    • Completion of decision tables with missing values.

    • Discretization of numerical attributes.

  • Computation

    • Support for both unsupervised and supervised learning.

    • Support for user-defined notions of discernibility.

    • Efficient computation of exact or approximate reducts, for various types of discernibility.

    • Generation of if-then rules or descriptive patterns via reducts.

    • Execution of script files.

    • Support for cross-validation.

  • Postprocessing

    • Advanced filtering of sets of reducts and rules.

  • Validation and analysis

    • Application of synthesized rules to unseen examples.

    • Generation of confusion matrices, ROC curves and calibration curves.

    • Evaluation of individual rules according to advanced measures of quality.

    • Utilities for statistical hypothesis testing.

  • Miscellaneous

    • Clustering via tolerance relations.

    • Computation of partitions and variable precision rough set approximations.

    • Support for random sampling of observations.

    • Open source code.

    • Documentation.
