Tiange Xiang    向天戈

I am a first-year Ph.D. student in Stanford Vision and Learning Lab (SVL) at the Stanford University. I'm currently rotating with Prof. Fei-Fei Li.

I received my Bachelor's degree from The University of Sydney, where I was fortunate to work with Prof. Weidong Cai. I was awarded Honors Class I and The University Medal.

I have particular research interests on Machine Learning & Computer Vision.

In-painting Radiography Images for Unsupervised Anomaly Detection
Tiange Xiang, Yixiao Zhang, Yongyi Lu, Alan L. Yuille, Chaoyi Zhang, Weidong Cai,
and Zongwei Zhou
Under review

We re-formulated unsupervised anomaly detection for radiography images as semantic-sapce in-painting.

In Guiding Body Meshes to Global 3D Coordinates from a Monocular RGB Image
Tiange Xiang, Yutian Lei, Jun Liu, and Dong Huang
Under review

We achieved person detection, SMPL regression, 'real' camera-coordinate 3D localization in one hybrid-framework.

Walk in the Cloud: Learning Curves for Point Clouds Shape Analysis
Tiange Xiang, Chaoyi Zhang, Yang Song, Jianhui Yu, and Weidong Cai
IEEE/CVF International Conference on Computer Vision (ICCV), 2021

We proposed a geometry-aware feature aggregation operator for point cloud analysis. SOTA performances on multiple fundamental benchmarks.

Towards Bi-directional Skip Connections in Encoder-Decoder Architectures and Beyond
Tiange Xiang, Chaoyi Zhang, Xinyi Wang, Yang Song, Dongnan Liu, Heng Huang,
and Weidong Cai
Medical Image Analysis, 2022

A very efficient and light-weight encoder-decoder network that achieved SOTA performances on multiple 2D and 3D medical image segmentation benchmarks.

BiX-NAS: Searching Efficient Bi-directional Architectures for Medical Image Segmentation
Xinyi Wang*, Tiange Xiang*, Chaoyi Zhang, Yang Song, Dongnan Liu, Heng Huang,
and Weidong Cai
International Conference on Medical Image Computing and Computer-Assisted Intervention (MICCAI), 2021

We proposed a two-phase NAS method to search a super efficient bi-directional architecture for medical image segmentation.

BiO-Net: Learning Recurrent Bidirectional Connections for Encoder-Decoder Architecture
Tiange Xiang, Chaoyi Zhang, Dongnan Liu, Yang Song, Heng Huang,
and Weidong Cai
International Conference on Medical Image Computing and Computer-Assisted Intervention (MICCAI), 2020

We proposed bi-directional skip connections in the encoder-decoder architecture. Better performances can be achived without increasing network parameter.

DSNet: A Weakly-Supervised Dual-Stream Framework for Effective Gigapixel Pathology Image Analysis
Tiange Xiang, Yang Song, Chaoyi Zhang, Dongnan Liu, Mei Chen, Fan Zhang,
Heng Huang, Lauren O'Donnell, and Weidong Cai
IEEE Transactions on Medical Imaging, 2022

We proposed an attention-based network to combine global-local visual clues for weakly-supervised WSI analysis.

Partial Graph Reasoning for Neural Network Regularization
Tiange Xiang, Chaoyi Zhang, Yang Song, Siqi Liu, Hongliang Yuan, and Weidong Cai

We formulated network regularization as generative distortions through learnable graph reasoning modules.

Two-Stage Monte Carlo Denoising with Adaptive Sampling and Kernel Pool
Tiange Xiang, Hongliang Yuan, Haozhi Huang, and Yujin Shi

We achieved real-time denoising for online rendering at adaptive spp counts. Multiple novel operators were designed in our two-phase denoising framework.
