Shelving, Stacking, Hanging: Relational Pose Diffusion for Multi-modal Rearrangement

no code implementations10 Jul 2023 Anthony Simeonov, Ankit Goyal, Lucas Manuelli, Lin Yen-Chen, Alina Sarmiento, Alberto Rodriguez, Pulkit Agrawal, Dieter Fox

We propose a system for rearranging objects in a scene to achieve a desired object-scene placing relationship, such as a book inserted in an open slot of a bookshelf.

SE(3)-Equivariant Relational Rearrangement with Neural Descriptor Fields

1 code implementation17 Nov 2022 Anthony Simeonov, Yilun Du, Lin Yen-Chen, Alberto Rodriguez, Leslie Pack Kaelbling, Tomas Lozano-Perez, Pulkit Agrawal

This formalism is implemented in three steps: assigning a consistent local coordinate frame to the task-relevant object parts, determining the location and orientation of this coordinate frame on unseen object instances, and executing an action that brings these frames into the desired alignment.

Vision Transformer for NeRF-Based View Synthesis from a Single Input Image

1 code implementation12 Jul 2022 Kai-En Lin, Lin Yen-Chen, Wei-Sheng Lai, Tsung-Yi Lin, Yi-Chang Shih, Ravi Ramamoorthi

Existing approaches condition on local image features to reconstruct a 3D object, but often render blurry predictions at viewpoints that are far away from the source view.

NeRF-Supervision: Learning Dense Object Descriptors from Neural Radiance Fields

no code implementations3 Mar 2022 Lin Yen-Chen, Pete Florence, Jonathan T. Barron, Tsung-Yi Lin, Alberto Rodriguez, Phillip Isola

In particular, we demonstrate that a NeRF representation of a scene can be used to train dense object descriptors.

CLA-NeRF: Category-Level Articulated Neural Radiance Field

no code implementations1 Feb 2022 Wei-Cheng Tseng, Hung-Ju Liao, Lin Yen-Chen, Min Sun

We propose CLA-NeRF -- a Category-Level Articulated Neural Radiance Field that can perform view synthesis, part segmentation, and articulated pose estimation.

Learning to See before Learning to Act: Visual Pre-training for Manipulation

no code implementations1 Jul 2021 Lin Yen-Chen, Andy Zeng, Shuran Song, Phillip Isola, Tsung-Yi Lin

With just a small amount of robotic experience, we can further fine-tune the affordance model to achieve better results.

Neural Volume Rendering: NeRF And Beyond

1 code implementation17 Dec 2020 Frank Dellaert, Lin Yen-Chen

Besides the COVID-19 pandemic and political upheaval in the US, 2020 was also the year in which neural volume rendering exploded onto the scene, triggered by the impressive NeRF paper by Mildenhall et al. (2020).

INeRF: Inverting Neural Radiance Fields for Pose Estimation

1 code implementation10 Dec 2020 Lin Yen-Chen, Pete Florence, Jonathan T. Barron, Alberto Rodriguez, Phillip Isola, Tsung-Yi Lin

We then show that for complex real-world scenes from the LLFF dataset, iNeRF can improve NeRF by estimating the camera poses of novel images and using these images as additional training data for NeRF.

Debiased Contrastive Learning

1 code implementation NeurIPS 2020 Ching-Yao Chuang, Joshua Robinson, Lin Yen-Chen, Antonio Torralba, Stefanie Jegelka

A prominent technique for self-supervised representation learning has been to contrast semantically similar and dissimilar pairs of samples.

Contrastive Learning Generalization Bounds +2

Experience-Embedded Visual Foresight

no code implementations12 Nov 2019 Lin Yen-Chen, Maria Bauza, Phillip Isola

In this paper, we tackle the generalization problem via fast adaptation, where we train a prediction model to quickly adapt to the observed visual dynamics of a novel object.
