Hi Faezeh,

The “performFcn” property of a neural network defines the function used to measure the network’s performance. The performance function is used to calculate network performance during training whenever “train” is called. Therefore, you can alter this property to your needs and set it to Mean Absolute Percentage Error (MAPE). To understand more about the “performFcn” property please refer to the following documentation - https://www.mathworks.com/help/deeplearning/ug/neural-network-object-properties.html#:~:text=the%20new%20function.-,net.performParam,-This%20property%20defines
