Chatterbox: Robust Transport for LLM Token Streaming under Unstable Network

no code implementations23 Jan 2024 Hanchen Li, YuHan Liu, Yihua Cheng, Siddhant Ray, Kuntai Du, Junchen Jiang

To render each generated token in real time, the LLM server generates response tokens one by one and streams each generated token (or group of a few tokens) through the network to the user right after it is generated, which we refer to as LLM token streaming.

Multi-Modal Gaze Following in Conversational Scenarios

1 code implementation9 Nov 2023 Yuqi Hou, Zhongqun Zhang, Nora Horanyi, Jaewon Moon, Yihua Cheng, Hyung Jin Chang

We then use the identity information to enhance scene images and propose a gaze candidate estimation network.

CacheGen: KV Cache Compression and Streaming for Fast Language Model Serving

1 code implementation11 Oct 2023 YuHan Liu, Hanchen Li, Yihua Cheng, Siddhant Ray, YuYang Huang, Qizheng Zhang, Kuntai Du, Jiayi Yao, Shan Lu, Ganesh Ananthanarayanan, Michael Maire, Henry Hoffmann, Ari Holtzman, Junchen Jiang

Compared to the recent systems that reuse the KV cache, CacheGen reduces the KV cache size by 3. 7-4. 3x and the total delay in fetching and processing contexts by 2. 7-3. 2x while having negligible impact on the LLM response quality in accuracy or perplexity.

DVGaze: Dual-View Gaze Estimation

1 code implementation ICCV 2023 Yihua Cheng, Feng Lu

We further propose a dual-view transformer to estimate gaze from dual-view features.

GRACE: Loss-Resilient Real-Time Video through Neural Codecs

no code implementations21 May 2023 Yihua Cheng, Ziyi Zhang, Hanchen Li, Anton Arapin, Yue Zhang, Qizheng Zhang, YuHan Liu, Xu Zhang, Francis Y. Yan, Amrita Mazumdar, Nick Feamster, Junchen Jiang

In real-time video communication, retransmitting lost packets over high-latency networks is not viable due to strict latency requirements.

Gaze Estimation using Transformer

1 code implementation30 May 2021 Yihua Cheng, Feng Lu

In this paper, we employ transformers and assess their effectiveness for gaze estimation.

PureGaze: Purifying Gaze Feature for Generalizable Gaze Estimation

1 code implementation24 Mar 2021 Yihua Cheng, Yiwei Bao, Feng Lu

Different from common domain adaption methods, we propose a domain generalization method to improve the cross-domain performance without touching target samples.

Adaptive Feature Fusion Network for Gaze Tracking in Mobile Tablets

no code implementations20 Mar 2021 Yiwei Bao, Yihua Cheng, Yunfei Liu, Feng Lu

Meanwhile, we also propose Adaptive Group Normalization to recalibrate eye features with the guidance of facial feature.

Appearance-Based Gaze Estimation via Evaluation-Guided Asymmetric Regression

no code implementations ECCV 2018 Yihua Cheng, Feng Lu, Xucong Zhang

Inspired by this, we design the multi-stream ARE-Net; one asymmetric regression network (AR-Net) predicts 3D gaze directions for both eyes with a novel asymmetric strategy, and the evaluation network (E-Net) adaptively adjusts the strategy by evaluating the two eyes in terms of their performance during optimization.
