ONeRF: Unsupervised 3D Object Segmentation from Multiple Views

no code implementations22 Nov 2022 Shengnan Liang, Yichen Liu, Shangzhe Wu, Yu-Wing Tai, Chi-Keung Tang

We present ONeRF, a method that automatically segments and reconstructs object instances in 3D from multi-view RGB images without any additional manual annotations.

A Grey-box Launch-profile Aware Model for C+L Band Raman Amplification

no code implementations24 Jun 2022 Yihao Zhang, Xiaomin Liu, Yichen Liu, Lilin Yi, Weisheng Hu, Qunbi Zhuge

Based on the physical features of Raman amplification, we propose a three-step modelling scheme based on neural networks (NN) and linear regression.

Learning Visual Styles from Audio-Visual Associations

no code implementations10 May 2022 Tingle Li, Yichen Liu, Andrew Owens, Hang Zhao

Our model learns to manipulate the texture of a scene to match a sound, a problem we term audio-driven image stylization.

Native Chinese Reader: A Dataset Towards Native-Level Chinese Machine Reading Comprehension

no code implementations13 Dec 2021 Shusheng Xu, Yichen Liu, Xiaoyu Yi, Siyuan Zhou, Huizi Li, Yi Wu

We present Native Chinese Reader (NCR), a new machine reading comprehension (MRC) dataset with particularly long articles in both modern and classical Chinese.

Improving Multi-Modal Learning with Uni-Modal Teachers

no code implementations21 Jun 2021 Chenzhuang Du, Tingle Li, Yichen Liu, Zixin Wen, Tianyu Hua, Yue Wang, Hang Zhao

We name this problem Modality Failure, and hypothesize that the imbalance of modalities and the implicit bias of common objectives in fusion method prevent encoders of each modality from sufficient feature learning.
