Hi Choong Yee,
There could be several reasons for the lack of consistency in the results. Here are a few things to implement:
- Data:
- Ensure that each class has enough samples for training to avoid bias.
- Remove outliers from the data to prevent inconsistencies.
2. Regularization:
- Inconsistent results can occur due to overfitting. Implement regularization techniques to deal with overfitting.
- You can use Bayesian Regularization with the "trainbr" function by adding the following line to your code:
net.trainFcn = ‘trainbr’
3. Monitoring and Loss function:
- If the testing accuracy is significantly lower than the training accuracy, apply regularization techniques.
- Monitor the value of the loss function for any sharp spikes. Consider changing the loss function to one that is more suitable for your data.

I hope it helps,
