A language model was trained exclusively on text sequences with a maximum length of 1024 tokens. When presented with a 2048-token sequence, two different approaches are considered for generating positional information for the new, unseen positions (1024 to 2047).
Approach X: The mechanism generates values for the new positions by continuing the mathematical pattern it learned from the original 0-1023 positions.
Approach Y: The mechanism rescales the positional indices of the entire 2048-token sequence so that they all map to values within the original 0-1023 range.
Which statement correctly categorizes these two approaches?

Choosing a Positional Embedding Generalization Strategy
A language model is trained on sequences up to a maximum length of
L. During inference, it encounters a sequence of length2L. Match each strategy for handling the unseen positions (Lto2L-1) with its corresponding classification.
