The first step in using GeneXproTools is launching it and opening existing files or creating new ones.

To Start GeneXproTools 5.0

  1. In Windows, click Start, point to Programs, and point to the Gepsoft GeneXproTools 5.0 folder.
    The icons in the Gepsoft GeneXproTools 5.0 folder appear in a list.
  2. Click the GeneXproTools 5.0 program icon.
    The Home Panel appears. This panel presents you with several choices, including start a new run or open an existing run.
  3. To start a new run, click the File menu and then choose New.
    The New Run Wizard appears. This wizard helps you gather the necessary information to start evolving a model.
  4. To open an existing run, in the Home Panel either choose a recent or sample run or click the File menu and then choose Open.
    In the Report Panel you will find relevant information concerning this run, including all the settings used in the run, the statistical evaluation of the best-of-run or active model, and a detailed account of all the models in the run History.
The new Home Panel of GeneXproTools 5.0

The GeneXproTools 5.0 modeling environment contains 10 basic panels:


Report Panel

In the Report Panel you can find relevant information concerning the run, including all the settings used in the run, the statistical evaluation of the best-of-run or active model (highlighted in yellow in the History heading), and a detailed account of the evolutionary history of the run.

Report Panel – Full & Short Report


Data Panel

The multifunctional Data Panel goes beyond a simple platform for analyzing and visualizing input data. Besides allowing the analysis and visualization of input variables, it also allows the visualization and analysis of all your models and derived variables, giving you access to a rich web of analyses between all these types of variables and across different datasets.

New Multifunctional Data Panel

The analyses you can do in the Data Panel include scatter plots and regression analysis between all possible pairs of variables (input variables, models and derived variables); histograms and summary statistics for all variables and across different datasets; different line charts for outlier detection and model analysis; and evaluation of the variable importance and display of the variable importance chart for all the models.

Variable importance of model variables

The multifunctional Data Panel also supports extensive record analyses, allowing you to study different types of records using different charts and browsing tools. For example, you can compare each record with different record prototypes in order to gain insight into both your data and your models. By selecting just the outliers or the misclassified records to browse, you can also perform error analysis in the Data Panel.

Settings Panel

The Settings Panel gives you access to the most important settings of GeneXproTools, which are organized into four different tabs: General Settings, Fitness Function, Genetic Operators, and Numerical Constants.


General Settings Tab

In the General Settings Tab you can change the number of training and validation/test records, choose different sub-sampling schemes for the training and validation/test datasets, change the chromosome architecture, the linking function, the number of chromosomes. Moreover, you can also choose the parameters for the Complexity Increase Engine of GeneXproTools and choose different modes of Model Management.

General Settings


Fitness Function Tab

In the Fitness Function Tab you can choose one of the 100+ GeneXproTools built-in fitness functions or design and test a fitness function of your own.

Genetic Operators Tab

In the Genetic Operators Tab you can change the degree of genetic modification you want to use during evolution by choosing the kind of genetic operators and their corresponding rates. Moreover, GeneXproTools provides 4 built-in modeling strategies that cover some of the most common modeling needs, namely a strategy for fine-tuning the numerical constants of your models (Constant Fine-Tuning); a strategy for model fine-tuning where the overall structure of the model remains basically unchanged making only small changes in the model’s structure (Model Fine-Tuning); a strategy for Sub-set Selection which is ideal for creating good random forests, especially for datasets with many variables, as it works only with the elements that were randomly drawn for the initial population; and of course a strategy designed for Optimal Evolution which tries to give a good blend of diversity versus stability in order to optimize and accelerate evolution.

Numerical Constants Tab

In the Numerical Constants Tab you can activate the algorithm that enables the use of random numerical constants and customize both the type and range of your constants, and the number of constants per gene.

Numerical Constants Tab


Functions Panel

In the Functions Panel you choose the functions GeneXproTools will use to model your data. For mathematical problems, there are a total of 279 built-in functions and comparison rules, whereas for Boolean problems there are a total of 258 built-in logical functions.

Functions Panel – Function Set Defaults


Run Panel

From the Run Panel you command and visualize the creation, optimization, and simplification of your models through the use of different model fitting charts, including different kinds of curve fitting charts, scatter plots, and residual charts. For Classification and Logistic Regression the model visualization tools include different binomial fitting charts, the classification scatter plot and the classification tapestry.

Run Panel – Classification & Logistic Regression


History Panel

The History Panel allows you to manage your models by selecting and re-ordering them using different Favorite Statistics. Moreover, you can also delete and import models from different runs and deploy models or model ensembles to Excel.

Model Selection in the History Panel


Results Panel

In the Results Panel a thorough statistical analysis of the evolved model is done on the fly both for the training and validation/test datasets. Furthermore, the model output and the target are compared using both a table and several charts. The number and type of available charts varies with the modeling category of the run.

Logistic Regression – Measures of Fit in the Results Panel


Predictions Panel

In the Predictions Panel is where you use your models to make predictions about future events in the Time Series Prediction Platform. Here is also where a thorough statistical analysis of your models takes place and, if in Testing Mode, it's also where you can test the predictive accuracy on past historical observations.

Curve Fitting – Time Series Prediction


Model Panel

In the Model Panel you can see the mathematical/logical intricacies of the evolved models in the universal representation of Expression Trees or automatically translate the native Karva Code into several programming languages (Ada, C, C++, C#, Excel VBA, Fortran, Java, JavaScript, Matlab, Octave, Pascal, Perl, PHP, Python, R, Visual Basic, VB.Net, Verilog, and VHDL).

Scoring Panel

In the Scoring Panel you can apply your models immediately without leaving the GeneXproTools environment. The scoring engine of GeneXproTools uses the JavaScript code of your models to score your data. Both Excel/Databases and Text Files can be scored and the output saved to Excel (csv) or text files. In addition, for small datasets, the output can also be observed in its entirety in the Scoring Panel.
