Controlling Overfitting with T5 Bias Buckets

Formula for Attention with T5 Bias (Unscaled)

Consider a hypothetical self-attention model that uses a relative positional encoding scheme where every unique query-key offset (e.g., -5, -4, ..., 0, ..., 4, 5) is assigned its own distinct, learnable bias parameter. How does the T5 approach, which groups many different offsets into a limited number of 'buckets' that share a single parameter, represent a key improvement over this hypothetical scheme, especially for handling sequences longer than those seen during training?
