Generalizable Neural Fields as Partially Observed Neural Processes

no code implementations ICCV 2023 Jeffrey Gu, Kuan-Chieh Wang, Serena Yeung

Neural fields, which represent signals as a function parameterized by a neural network, are a promising alternative to traditional discrete vector or grid-based representations.

NeMo: Learning 3D Neural Motion Fields From Multiple Video Instances of the Same Action

no code implementations CVPR 2023 Kuan-Chieh Wang, Zhenzhen Weng, Maria Xenochristou, João Pedro Araújo, Jeffrey Gu, Karen Liu, Serena Yeung

Empirically, we show that NeMo can recover 3D motion in sports using videos from the Penn Action dataset, where NeMo outperforms existing HMR methods in terms of 2D keypoint detection.

Staying in Shape: Learning Invariant Shape Representations using Contrastive Learning

no code implementations8 Jul 2021 Jeffrey Gu, Serena Yeung

Creating representations of shapes that are invari-ant to isometric or almost-isometric transforma-tions has long been an area of interest in shape anal-ysis, since enforcing invariance allows the learningof more effective and robust shape representations. Most existing invariant shape representations arehandcrafted, and previous work on learning shaperepresentations do not focus on producing invariantrepresentations.

Capturing implicit hierarchical structure in 3D biomedical images with self-supervised hyperbolic representations

no code implementations NeurIPS 2021 Joy Hsu, Jeffrey Gu, Gong-Her Wu, Wah Chiu, Serena Yeung

To that end, we consider encoder-decoder architectures with a hyperbolic latent space, to explicitly capture hierarchical relationships present in subvolumes of the data.

Learning Hyperbolic Representations for Unsupervised 3D Segmentation

no code implementations28 Sep 2020 Joy Hsu, Jeffrey Gu, Gong Her Wu, Wah Chiu, Serena Yeung

There exists a need for unsupervised 3D segmentation on complex volumetric data, particularly when annotation ability is limited or discovery of new categories is desired.
