Local-consistent Transformation Learning for Rotation-invariant Point Cloud Analysis

1 code implementation17 Mar 2024 Yiyang Chen, Lunhao Duan, Shanshan Zhao, Changxing Ding, DaCheng Tao

Equipped with LCRF and RPR, our LocoTrans is capable of learning local-consistent transformation and preserving local geometry, which benefits rotation invariance learning.

CharNeRF: 3D Character Generation from Concept Art

no code implementations27 Feb 2024 Eddy Chu, Yiyang Chen, Chedy Raissi, Anand Bhojan

3D modeling holds significant importance in the realms of AR/VR and gaming, allowing for both artistic creativity and practical applications.

Behavioral Refinement via Interpolant-based Policy Diffusion

no code implementations25 Feb 2024 Kaiqi Chen, Eugene Lim, Kelvin Lin, Yiyang Chen, Harold Soh

However, the target policy to be learned is often significantly different from Gaussian and this mismatch can result in poor performance when using a small number of diffusion steps (to improve inference speed) and under limited data.

Revealing Decurve Flows for Generalized Graph Propagation

no code implementations13 Feb 2024 Chen Lin, Liheng Ma, Yiyang Chen, Wanli Ouyang, Michael M. Bronstein, Philip H. S. Torr

\textbf{Secondly}, we propose the {\em Continuous Unified Ricci Curvature} (\textbf{CURC}), an extension of celebrated {\em Ollivier-Ricci Curvature} for directed and weighted graphs.

Using Human-like Mechanism to Weaken Effect of Pre-training Weight Bias in Face-Recognition Convolutional Neural Network

no code implementations20 Oct 2023 Haojiang Ying, Yi-Fan Li, Yiyang Chen

In this study, we focused on 4 extensively studied CNNs (AlexNet, VGG11, VGG13, and VGG16) which has been analyzed as human-like models by neuroscientists with ample evidence.

Cross-modal & Cross-domain Learning for Unsupervised LiDAR Semantic Segmentation

no code implementations5 Aug 2023 Yiyang Chen, Shanshan Zhao, Changxing Ding, Liyao Tang, Chaoyue Wang, DaCheng Tao

In recent years, cross-modal domain adaptation has been studied on the paired 2D image and 3D LiDAR data to ease the labeling costs for 3D LiDAR semantic segmentation (3DLSS) in the target domain.

Machine learning based iterative learning control for non-repetitive time-varying systems

no code implementations1 Jul 2021 Yiyang Chen, Wei Jiang, Themistoklis Charalambous

A machine learning (ML) based nominal model update mechanism, which utilizes the linear regression technique to update the nominal model at each ILC trial only using the current trial information, is proposed for non-repetitive TVSs in order to enhance the ILC performance.
