Megaputer announced a new release of its award-winning data mining solutions: PolyAnalyst PRO for Win NT and PolyAnalyst Power for Win 95. The new comprehensive multi-strategy solutions utilize an additional self-learning algorithm – PolyNet Predictor – a hybrid between the GMDH and Neural Net approaches, most efficient when processing large volumes of data. Both PolyAnalyst PRO and Power feature similar graphical user interface. In addition to utilizing enhanced data manipulation, visualization and report generating capabilities, users of PolyAnalyst PRO/Power take advantage of the following machine learning algorithms:
- PolyNet Predictor
- Find Laws*
- Find Dependencies
*Available only in PolyAnalyst PRO.
PolyAnalyst PRO and Power provide the following capabilities for data analysis:
Both systems can directly access data held in Oracle, DB2, Informix, Sybase, MS SQL Server, Ingres, or any other ODBC-compliant database. Data and exploration results can be exchanged with MS Excel 7.0 or 97. New data can be added to the project when necessary. A customized version of PolyAnalyst PRO or Power comes merged with the IBM Visual Warehouse or ORACLE Express.
Data Manipulation and Cleansing
Records can be selected according to multiple criteria. A union, intersection, or complement of datasets can be created. Rules, automatically discovered by PolyAnalyst or entered by the user, can be used to produce new fields. Exceptional records can be filtered out. The drill-through feature allows selecting data points for a new dataset visually from a chart. Data can be split into n-tile percentage intervals for any numerical variable.
PolyAnalyst PRO and Power provide a broad selection of self-learning engines for data analysis. Out of seven unique exploration engines mentioned above, a new PolyNet Predictor is a newly developed innovative tool. It combines the power of Group Method Data Handling and Neural Net technologies to predict values of numerical variables. As always, the statistical significance of the results obtained by each engine of PolyAnalyst is rigorously checked.
PolyAnalyst has an easy-to-use graphical user interface. Data and exploration results can be visualized in numerous formats: histograms, line and point plots with zoom and drill-through capabilities, colored charts for three dimensions, interactive Rule-Graphs with sliders for effective presentation of multidimensional relations, allowing the user to “feel” the discovered relation. In addition, there is a special Frequencies function providing for a quick and thorough visualization of the distribution of categorical, integer, or yes/no variables.
Discovered relations are readily incorporated in existing DSS or EIS systems. The Print Form feature provides for the generation of an advanced output including a mixture of text, graphics, and system reports. A PolyAnalyst project file contains all the results of the performed data exploration. Created datasets and summary statistics can be exported to MS Excel.
An evaluation copy of PolyAnalyst supported by a series of interactive lessons in data mining from various application fields are available for downloading from http://www.megaputer.ru.
To master PolyAnalyst the user can follow the carefully documented examples step by step.
PolyAnalyst Power — MS Windows 95 or NT
PolyAnalyst PRO — MS Windows NT
PolyAnalyst is an award winning complete multi-strategy data mining environment based on the latest achievements in automated knowledge discovery in databases. A broad selection of exploration engines allows the user to predict values of continuous variables, explicitly model complex phenomena, determine the most influential independent variables, and solve classification and clustering tasks. The ability of PolyAnalyst to present the discovered relations in explicit symbolic form has no world analogs. An object-oriented design, point-and-click GUI, versatile data manipulation, visualization, and reporting capabilities, minimum of statistics, and a simple interface to various data storage architectures make PolyAnalyst a very easy-to-use system.
