Data Sets and the Data Set Manager
Data in NeuralTools is structured around cases and variables. You
work with a data set, or a set of statistical variables, located in
contiguous columns with variable names in the first row of the data
set. Each row in the data set is a case. Each case has a set of
independent variable values and either a known or missing value for
the dependent output variable. It is the job of NeuralTools to predict
output variable values for cases where they are not known.
The NeuralTools Data Set Manager allows you to define your data
sets, variables and cases. You can then use these predefined variables
for training and testing neural networks, without re-selecting the data
you wish to analyze over and over. You may place all known,
historical cases in one data set and cases you wish to predict results
for in a different data set. You can also combine all your data –
known historical data and data you wish to predict - in a single data
set.
