I need calculate Accuracy, Precision and Recall

[yamepg]

Dear Professor:
I have reading your work , and I think that is a very interesting research. I'm trying to replicate some experiments with your STNN, but in addition to MSE, I need to calculate accuracy, precision and recall. Could you help me to know if with the output data of the model and the prediction I can calculate these metrics. Is the first time that I work with neural networks and I have few experience in this area. Thanks in advance by your time,
Best regard, Yamel.
