A. Creating the Network

1. Use the following parameters to create your first FuNN neural network using FuzzyCope/3:

   Network Architecture:
   

   Number of Inputs	4
   Number of Members	3	(3 Memberhip Functions per input, eg High, Medium, Low)
   Number of Rules	5
   Number of Outputs	3
   Number of Actions	2	(2 Memberhip Functions per input, eg High, Low)

2. Press the create button.

3. Save the network as IrisFUNN.wgt

4. View the network

B. Training the network

In neural net applications the weights are determined so that they minimise the Root Mean Squared errors (RMSE).

1. Open the training file that you formatted earlier - Iris.trn

2. View the training file

3. Set the parameters for your Iris neural network:
   

   Learning Rate	0.3
   Momentum	0.6
   Epochs	100 then 500 (increase until the terminating error is reached)
   Terminating Error	0.01
   Training Mode	Batch

4. Press the Train button to commence training

5. Save the trained network as TIrisFUNN.wgt

C. GA Training

1. If your training error isn't going down try some GA (Genetic Algorithm) training. Use the following parameters:
   

   Population Size	50
   Minimum Weight	-20
   Maximum Weight	20
   Mutation Rate	0.01
   Generations	100
   Terminating Error	0.01
   Fitness Normalisation	Unchecked
   Elitism	Checked
   Crossover points	1
   Selection strategy	Tournament

   The training error will result.

2. Save the trained network again as TIrisFUNN.wgt

D. Network Evaluation

1. Choose the Recall Tab

2. Open the recall file that you formatted earlier - Iris.rcl

3. Open a new output file for the results and name it IrisFUNN.out

4. Press the Recall Button.

5. Save the new output file.

6. View the Output file.

7. Compare your results with the desired outputs

E. Extracting Rules

1. Choose the Extract Rules Tab

2. Press the label button

3. Save the label file (using the Save As Label file option from the Extract Rules menu)

4. Open the label file in a text editor and modify the labels

5. Return to FuNN and load the modified label file

6. Set the Threshold values
   

   Threshold In	1.0
   Threshold Out	1.0

7. Press the Extract Rules button

8. View your rule file (using the View Rule file option from the Extract Rules menu)
