RotateKV: Accurate and Robust 2-Bit KV Cache Quantization for LLMs via Outlier-Aware Adaptive Rotations

no code implementations25 Jan 2025 Zunhai Su, Zhe Chen, Wang Shen, Hanyu Wei, Linge Li, Huangqi Yu, Kehong Yuan

Existing KV quantization rely on fine-grained quantization or the retention of a significant portion of high bit-widths caches, both of which compromise compression ratio and often fail to maintain robustness at extremely low average bit-widths.

Sharingan: Extract User Action Sequence from Desktop Recordings

no code implementations13 Nov 2024 Yanting Chen, Yi Ren, Xiaoting Qin, Jue Zhang, Kehong Yuan, Lu Han, QIngwei Lin, Dongmei Zhang, Saravan Rajmohan, Qi Zhang

Video recordings of user activities, particularly desktop recordings, offer a rich source of data for understanding user behaviors and automating processes.

MIPR:Automatic Annotation of Medical Images with Pixel Rearrangement

no code implementations22 Apr 2022 Pingping Dai, Haiming Zhu, Shuang Ge, Ruihan Zhang, Xiang Qian, Xi Li, Kehong Yuan

In this paper, inspired by self-training of semi-supervised learning, we pro? pose a novel approach to solve the lack of annotated data from another angle, called medical image pixel rearrangement (short in MIPR).

The Method of Multimodal MRI Brain Image Segmentation Based on Differential Geometric Features

no code implementations10 Nov 2018 Yongpei Zhu, Zicong Zhou, Guojun Liao, Qianxi Yang, Kehong Yuan

In this paper, we use the differential geometric information including JD and CV as image characteristics to measure the differences between different MRI images, which represent local size changes and local rotations of the brain image, and we can use them as one CNN channel with other three modalities (T1-weighted, T1-IR and T2-FLAIR) to get more accurate results of brain segmentation.
