Rotary Position Embedding (RoPE) encodes token positions by rotating each two-dimensional channel of the query and key vectors at a channel-specific frequency, making the attention logits invariant to a common shift of positions. However, this rotation is periodic, and it leads to position aliasing where relative posit...

A key consequence is that the optimal learning rate depends only on the number of unique layers $L$, not on the loop count $N, enabling direct hyperparameter transfer from small to large $N$ without retuning.

It is shown that existing hallucination detection methods, such as confidence-based filtering and inner-state probing, fundamentally fail in the presence of spurious correlations, and further elucidates why these statistical biases intrinsically undermine confidence-based detection techniques.
Results show that looping can improve Transformers even under budget matching, offering a practical recipe that turns depth reuse into measurable gains.
