Unveiling the Generalization Power of Fine-Tuned Large Language Models

1 code implementation14 Mar 2024 Haoran Yang, Yumeng Zhang, Jiaqi Xu, Hongyuan Lu, Pheng Ann Heng, Wai Lam

While Large Language Models (LLMs) have demonstrated exceptional multitasking abilities, fine-tuning these models on downstream, domain-specific datasets is often necessary to yield superior performance on test sets compared to their counterparts without fine-tuning.

Multi-functional OFDM Signal Design for Integrated Sensing, Communications, and Power Transfer

no code implementations31 Oct 2023 Yumeng Zhang, Sundar Aditya, Bruno Clerckx

To characterize the ISCAP performance region, we assume symbols with non-zero mean asymmetric Gaussian distribution (i. e., the input distribution), and optimize its mean and variance at each subcarrier to maximize the harvested power, subject to constraints on the achievable rate (communications) and the average side-to-peak-lobe difference (sensing).

Forward Flow for Novel View Synthesis of Dynamic Scenes

Input Distribution Optimization in OFDM Dual-Function Radar-Communication Systems

no code implementations11 May 2023 Yumeng Zhang, Sundar Aditya, Bruno Clerckx

However, the overall power allocation (i. e., the sum of mean and variance) across the OFDM subcarriers and symbols is similar to (1).

Waveform Design for Wireless Power Transfer with Power Amplifier and Energy Harvester Non-Linearities

no code implementations2 Apr 2022 Yumeng Zhang, Bruno Clerckx

Current research has optimized transmit waveform, adaptive to channel state information (CSI), to maximize the harvested power in WPT while accounting for energy harvester (EH)'s non-linearity.

Waveform Optimization for Wireless Power Transfer with Power Amplifier and Energy Harvester Non-Linearities

no code implementations28 Nov 2021 Yumeng Zhang, Bruno Clerckx

Waveform optimization has recently been shown to be a key technique to boost the efficiency and range of far-field wireless power transfer (WPT).

Improving Robustness for Pose Estimation via Stable Heatmap Regression

no code implementations8 May 2021 Yumeng Zhang, Li Chen, Yufeng Liu, Xiaoyan Guo, Wen Zheng, Junhai Yong

Deep learning methods have achieved excellent performance in pose estimation, but the lack of robustness causes the keypoints to change drastically between similar images.
