Vosh: Voxel-Mesh Hybrid Representation for Real-Time View Synthesis

no code implementations11 Mar 2024 Chenhao Zhang, Yongyang Zhou, Lei Zhang

The neural radiance field (NeRF) has emerged as a prominent methodology for synthesizing realistic images of novel views.

GraphInstruct: Empowering Large Language Models with Graph Understanding and Reasoning Capability

1 code implementation7 Mar 2024 Zihan Luo, Xiran Song, Hong Huang, Jianxun Lian, Chenhao Zhang, Jinqi Jiang, Xing Xie

To evaluate and enhance the graph understanding abilities of LLMs, in this paper, we propose a benchmark named GraphInstruct, which comprehensively includes 21 classical graph reasoning tasks, providing diverse graph generation pipelines and detailed reasoning steps.

CaMU: Disentangling Causal Effects in Deep Model Unlearning

1 code implementation30 Jan 2024 Shaofei Shen, Chenhao Zhang, Alina Bialkowski, Weitong Chen, Miao Xu

To address this shortcoming, the present study undertakes a causal analysis of the unlearning and introduces a novel framework termed Causal Machine Unlearning (CaMU).

AdaNIC: Towards Practical Neural Image Compression via Dynamic Transform Routing

1 code implementation ICCV 2023 Lvfang Tao, Wei Gao, Ge Li, Chenhao Zhang

Compressive autoencoders (CAEs) play an important role in deep learning-based image compression, but large-scale CAEs are computationally expensive.

A Boosting Algorithm for Positive-Unlabeled Learning

no code implementations19 May 2022 Yawen Zhao, Mingzhe Zhang, Chenhao Zhang, Weitong Chen, Nan Ye, Miao Xu

This is because AdaPU learns a weak classifier and its weight using a weighted positive-negative (PN) dataset with some negative data weights $-$ the dataset is derived from the original PU data, and the data weights are determined by the current weighted classifier combination, but some data weights are negative.
