This PR adds the new and improved "by parts" correction to the NTK-aware interpolation method. This corrected method improves from previous methods fourfold: Decreases PPL in all context lengths when used on non-finetuned models compared to previous NTK-Aware method, especially for higher context sizes as alpha value can be set much lower for same context size. Removes the alpha parameter, which did not accurately predict effective context length and was variable across different models. Now uses same scale parameter as linear interpolation which is much more intuitive and less prone to…
