Some new rotation-based quantization methods.

[FelixMessi]

Thank you for organizing such a comprehensive survey on small language models. I found it highly informative and insightful. To further enrich the literature coverage, I would like to suggest including some recent works on rotation-based quantization methods:

QuaRot (https://arxiv.org/abs/2404.00456)
DuQuant (https://arxiv.org/abs/2406.01721)
SpinQuant (https://dl.acm.org/doi/10.1145/3636534.3649361)
OstQuant (https://arxiv.org/abs/2501.13987)

Thank you for considering these additions.
