Because, let's be real, your overfitting is just embarrassing
Welcome, sissie! If your neural network is more accurate on the training data than a toddler with a Ouija board, it's probably because you're overfitting. Regularization is here to save the day!
Think of it like a sissy who can't stop crying because their favorite reality TV show is on. You've got a model that's too good at your training data, but it's a mess on real data. We're not talking about a sissy, though - we're talking about Regularization.
