The first step in using GeneXproTools is launching it and opening existing files or creating new ones.
To Start GeneXproTools 4.3
- In Windows, click Start, point to Programs, and point to the Gepsoft
GeneXproTools 4.3 folder.
The icons in the Gepsoft GeneXproTools 4.3 folder appear in a list.
- Click the GeneXproTools 4.3 program icon.
The Welcome Screen appears. This welcome screen presents you with several choices, including start a new run or open an existing run.
- To start a new run, in the Welcome Screen choose the command New
run or 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.
- To open an existing run, in the Welcome Screen choose the command Open
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 the evolutionary history of the
run.
The GeneXproTools 4.3 modeling environment contains 10 basic panels:
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.
In the Data Panel you can visualize both the training and testing data,
check easily the distribution of all variables and how each one of
them relates to the dependent variable using the scatter plot, change a data set, or choose a subset of your data to use either
for training or testing.
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.
In the General Settings Tab you can change the number of
training and testing samples, the chromosome architecture, the linking function, the population
size, and choose the parameters for the Complexity Increase Engine
of GeneXproTools. You can also change the Model Management settings.
In the Fitness Function Tab you can choose one of the 36 GeneXproTools
built-in fitness functions or design and test a fitness function of your own.
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.
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, the number of constants per gene, and also choose the genetic operators especially designed
for fine-tuning the random constants in your models.
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.
From the Run Panel you command
and observe the creation, optimization, and simplification of your
models through the use of eight different kinds of plots, including
a Curve Fitting plot to show how well the model being designed is
fitting your data. For Classification and Logic Synthesis problems the
options are the Classification Tapestry or the Target/Model chart.
The History Panel allows you
to delete models, import models from different runs and deploy a model or an ensemble to Excel.
In the Results Panel a thorough
statistical analysis of the evolved model is done on the fly both
for the training and testing sets. 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 problem category of the run.
In the Predictions Panel is
where you use the evolved model to make predictions about future
events in Time Series Prediction. Here is also where a thorough
statistical analysis of the evolved model takes place and, if in
Testing Mode, and is also where you can test the predictive
accuracy on the testing samples.
In the Model Panel you can see the mathematical/logical intricacies of the evolved model 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, Java Script, Matlab,
Pascal, Perl, PHP, Python, Visual Basic, VB.Net, Verilog, and VHDL).
In the Scoring Panel you can
apply the evolved model 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 from the Scoring Panel.
