The New Network dialog is used for the creation and growth of a new neural network from the values in the Grid. During optimization a new network is created every time the period of cycles or seconds completes. The number of hidden nodes in each layer that is checked grows from minimum to maximum. Each network is checked by training it for a short period. The network that produces the lowest error is selected for further training and validating.
Unconnected frameworks can be created without connections if the Network Editor is to be used.
 Growth rate
A network is produced when the cycles or seconds elapses until the optimum network is found.

 Input layer
The number of nodes in the input layer is determined by the number of input columns in the grid.
|
|
|
 Hidden layers
The hidden layers are grown from the minimum to the maximum number of nodes.
|
|
|
 Output layer
The number of nodes in the output layer is determined by the number of output columns in the grid.

|
|
 Connect layers
If checked all connections are created automatically. If not checked the optimum number of nodes will be created but not connected together. This is so that the network editor can be used to produce complex configurations.
