Language models learn token distance with learned positional increments

Researchers have explored a novel method for language models to learn positional increments for each token, rather than relying on a fixed +1 advancement. This technique, applied to small transformer models, allows the model to develop its own understanding of the distance between tokens, varying this increment per layer. While initial experiments show no performance improvement, this approach offers a new avenue for inspecting model behavior and understanding attention patterns, though its practical utility is still under investigation.
