Questiоn 18: Fоr neurаl netwоrks/deep leаrning regression models, the number of pаrameters can be huge. Does it make sense to compare two neural network models for a continuous response solely based on the in-sample model MSE as defined above? Why out-of-sample MSPE is a generally better model comparison criterion than the in-sample MSE?
