Relational Representation Learning Network for Cross-Spectral Image Patch Matching

no code implementations18 Mar 2024 Chuang Yu, Yunpeng Liu, Jinmiao Zhao, Dou Quan, Zelin Shi

Therefore, an innovative relational representation learning idea is proposed for the first time, which simultaneously focuses on sufficiently mining the intrinsic features of individual image patches and the relations between image patch features.

Layerwise Proximal Replay: A Proximal Point Method for Online Continual Learning

no code implementations14 Feb 2024 Jason Yoo, Yunpeng Liu, Frank Wood, Geoff Pleiss

Our solution, Layerwise Proximal Replay (LPR), balances learning from new and replay data while only allowing for gradual changes in the hidden activation of past data.

Risk Taxonomy, Mitigation, and Assessment Benchmarks of Large Language Model Systems

no code implementations11 Jan 2024 Tianyu Cui, Yanling Wang, Chuanpu Fu, Yong Xiao, Sijia Li, Xinhao Deng, Yunpeng Liu, Qinglin Zhang, Ziyi Qiu, Peiyang Li, Zhixing Tan, Junwu Xiong, Xinyu Kong, Zujie Wen, Ke Xu, Qi Li

Based on this, we propose a comprehensive taxonomy, which systematically analyzes potential risks associated with each module of an LLM system and discusses the corresponding mitigation strategies.

Self-supervision meets kernel graph neural models: From architecture to augmentations

no code implementations17 Oct 2023 Jiawang Dan, Ruofan Wu, Yunpeng Liu, Baokun Wang, Changhua Meng, Tengfei Liu, Tianyi Zhang, Ningtao Wang, Xing Fu, Qi Li, Weiqiang Wang

Recently, the idea of designing neural models on graphs using the theory of graph kernels has emerged as a more transparent as well as sometimes more expressive alternative to MPNNs known as kernel graph neural networks (KGNNs).

Video Killed the HD-Map: Predicting Multi-Agent Behavior Directly From Aerial Images

no code implementations19 May 2023 Yunpeng Liu, Vasileios Lioutas, Jonathan Wilder Lavington, Matthew Niedoba, Justice Sefas, Setareh Dabiri, Dylan Green, Xiaoxuan Liang, Berend Zwartsenberg, Adam Ścibior, Frank Wood

The development of algorithms that learn multi-agent behavioral models using human demonstrations has led to increasingly realistic simulations in the field of autonomous driving.

OBBStacking: An Ensemble Method for Remote Sensing Object Detection

1 code implementation27 Sep 2022 Haoning Lin, Changhao Sun, Yunpeng Liu

Trying to address these problems, this paper proposes OBBStacking, an ensemble method that is compatible with OBBs and combines the detection results in a learned fashion.

Vehicle Type Specific Waypoint Generation

no code implementations9 Aug 2022 Yunpeng Liu, Jonathan Wilder Lavington, Adam Scibior, Frank Wood

We develop a generic mechanism for generating vehicle-type specific sequences of waypoints from a probabilistic foundation model of driving behavior.

Critic Sequential Monte Carlo

no code implementations30 May 2022 Vasileios Lioutas, Jonathan Wilder Lavington, Justice Sefas, Matthew Niedoba, Yunpeng Liu, Berend Zwartsenberg, Setareh Dabiri, Frank Wood, Adam Scibior

We introduce CriticSMC, a new algorithm for planning as inference built from a composition of sequential Monte Carlo with learned Soft-Q function heuristic factors.
