Weeks ago,u/emozillaproposed an improvement on NTK-Aware RoPR in thispost, later named DynamicNTKScalingRotaryEmbedding. The main idea behind Dynamic NTK involves incorporating a scaling factor relative to the present decoding sequence length to improve the base functionality. However, there is actua...

是否有必要支持dynamic ntk main分支目前好像是不支持dynamic ntk,不过看这个帖子https://www.reddit.com/r/LocalLLaMA/comments/14mrgpr/dynamically_scaled_rope_further_increases/ 从图中看,dynamic ntk能取到综合长短文本的最低ppl。 是否有必要支持dynamic ntk呢?
YaRN (Yet another RoPE extension method) combines the NTK-By-Parts Interpolation and Attention Scaling methods, improving upon existing RoPE interpolation methods for longer context window sizes. Fine-tuned models maintain their original performance across benchmarks while enabling efficient extrapolation an...

This large set of samples requires a high number of simulations, which by extension requires a very high computational time (exponentially scaling up to an unmanageable level). In order to control and reduce this large number, a fixed set of levels for every factor have been considered, ...
