A team trains a decoder-only Transformer for next-word prediction. During training, an implementation mistake allows each position to attend not only to earlier tokens but also to future ground-truth tokens.Training loss becomes unusually low, but generation quality at inference is disappointing.What is the best explanation?

Scenario D: Revenue Prediction (Regression)A business predicts weekly revenue using features like ad_spend, number_of_customers, and average_discount.Two models are evaluated on a held-out test set: Model A: R² = 0.62, RMSE = 18,000 Model B: R² = 0.58, RMSE = 16,000 Lower RMSE is better. Higher R² is better.If the business cares about minimizing typical dollar error in forecasts, they should prefer:
