[Verse 1] Sarah builds a model, feeds it training data Every single detail, memorized like scripture Perfect scores on tests she's seen before But when fresh numbers knock upon her door The model stumbles, fails to recognize What seemed so clear has become foreign lies [Chorus] Overfitting steals the show Memorizing all you know Cross-validation saves the day Split your data, test the way Hold some back, don't let it peek Train on some, then let it speak To the hidden, unseen crowd That's when models make you proud [Verse 2] Like a student cramming every textbook page Word for word, but missing wisdom's sage When exam day brings a different question style All that rote recall won't help them smile Models need to learn the deeper rules Not just copy answers like mere tools [Chorus] Overfitting steals the show Memorizing all you know Cross-validation saves the day Split your data, test the way Hold some back, don't let it peek Train on some, then let it speak To the hidden, unseen crowd That's when models make you proud [Bridge] K-fold cross divides the deck Every piece gets its turn to check Training set builds up the brain Validation keeps it sane Test set waits behind the curtain Making sure your model's certain [Verse 3] Complexity can be a wicked trap Too many features in your model's map Regularization pulls the reins Keeps your algorithm from going insane Simple often beats the fancy dance When prediction needs a fighting chance [Final Chorus] Overfitting steals the show Memorizing all you know Cross-validation saves the day Split your data, test the way Generalize, don't just rehearse Make your model universe- Ready for tomorrow's test That's when you'll perform your best
