In a self-attention mechanism, a bias term is added to the score calculated between a query at position i and a key at position j. Consider a scenario where this bias term is designed to be a large negative value when the distance |i - j| is large, and it approaches zero as the distance gets smaller. How would this specific design influence the model's behavior?
