Hi Kwaku,
To change the performance function, you must implement a custom performance function to evaluate the performance as “net.performFcn”does not provide option for custom function . Thus, you cannot directly integrate it as “net.performFcn” expects the functions to be predefined . Hence you can evaluate the performance using your own custom function as shown below:
function rmse = calculateRMSE(targets, outputs)
mse = mean((targets - outputs).^2, 'all'); % Calculate MSE
rmse = sqrt(mse); % Calculate RMSE from MSE
end
outputs = net(inputs); % Get the network's outputs for the input data
rmse = calculateRMSE(targets, outputs); % Calculate RMSE using your custom function
For more information on net.performFcn refer below:
Hope this helps!
Best regards,
