public Substrate ( List |
||
| nodeSetList | List |
Substrate nodes, represented as distinct sets of nodes. By convention the first and second /// sets in the list represent the input and output noes respectively. All other sets represent hidden nodes. |
| activationFnLibrary | IActivationFunctionLibrary | The activation function library allocated to the networks that are 'grown' from the substrate. |
| activationFnId | int | The ID of an activation function in activationFnLibrary. This is the activation function /// ID assigned to all nodes in networks that are 'grown' from the substrate. |
| weightThreshold | double | The weight threshold below which substrate connections are not created in grown networks. |
| maxWeight | double | Defines the weight range of grown connections (+-maxWeight). |
| connectionList | List |
A predetermined list of substrate connections. |
