Cross-Validation

Cross-Validation (CV) - Model validation technique used to evaluate how good a predictive model will perform in practice. It splits data multiple times in different places so the predictive model doesn't guide exclusively on one piece of data and decreasing the risk of overfitting making the model more reliable.

Is your model giving good results?
Yes, ever since I implemented cross-validation.

Get off the cross

Playing the martyr when you are the one that is unfairly treating someone else.

"How dare you get angry at me cheating on you - if you were doing what I wanted and giving me what I needed I wouldn't cheat"

Get off the cross - no matter what I did or didn't give you cheating is not right and you know it.
