Interpretable Generative Models through Post-hoc Concept Bottlenecks

1 code implementation25 Mar 2025 Akshay Kulkarni, Ge Yan, Chung-En Sun, Tuomas Oikarinen, Tsui-Wei Weng

Concept bottleneck models (CBM) aim to produce inherently interpretable models that rely on human-understandable concepts for their predictions.

Humanoid Policy ~ Human Policy

no code implementations17 Mar 2025 Ri-Zhao Qiu, Shiqi Yang, Xuxin Cheng, Chaitanya Chawla, Jialong Li, Tairan He, Ge Yan, David J. Yoon, Ryan Hoque, Lars Paulsen, Ge Yang, Jian Zhang, Sha Yi, Guanya Shi, Xiaolong Wang

The state-action space of HAT is unified for both humans and humanoid robots and can be differentiably retargeted to robot actions.

Movable Antenna Aided Multiuser Communications: Antenna Position Optimization Based on Statistical Channel Information

no code implementations28 Feb 2025 Ge Yan, Lipeng Zhu, Rui Zhang

To address this issue, we propose in this paper a new approach to optimize the MA positions based on the users' statistical CSI over a large timescale.

Integrating LMM Planners and 3D Skill Policies for Generalizable Manipulation

no code implementations30 Jan 2025 Yuelei Li, Ge Yan, Annabella Macaluso, Mazeyu Ji, Xueyan Zou, Xiaolong Wang

In aligning high-level and low-level control for robot actions, language embeddings representing the high-level policy are jointly attended with the 3D feature field in the 3D transformer for seamless integration.

Power Measurement Enabled Channel Autocorrelation Matrix Estimation for IRS-Assisted Wireless Communication

no code implementations20 Jul 2024 Ge Yan, Lipeng Zhu, Rui Zhang

Prior works on IRS CSI acquisition mainly estimate IRS-cascaded channels based on the extra pilot signals received at the users/base station (BS) with time-varying IRS reflections, which, however, needs to modify the existing channel training/estimation protocols of wireless systems.

VLG-CBM: Training Concept Bottleneck Models with Vision-Language Guidance

1 code implementation18 Jul 2024 Divyansh Srivastava, Ge Yan, Tsui-Wei Weng

Concept Bottleneck Models (CBMs) provide interpretable prediction by introducing an intermediate Concept Bottleneck Layer (CBL), which encodes human-understandable concepts to explain models' decision.

Provably Robust Conformal Prediction with Improved Efficiency

1 code implementation30 Apr 2024 Ge Yan, Yaniv Romano, Tsui-Wei Weng

To address these limitations, we first propose a novel framework called RSCP+ to provide provable robustness guarantee in evaluation, which fixes the issues in the original RSCP method.

DNAct: Diffusion Guided Multi-Task 3D Policy Learning

no code implementations7 Mar 2024 Ge Yan, Yueh-Hua Wu, Xiaolong Wang

To learn a generalizable multi-task policy with few demonstrations, the pre-training phase of DNAct leverages neural rendering to distill 2D semantic features from foundation models such as Stable Diffusion to a 3D space, which provides a comprehensive semantic understanding regarding the scene.

Channel Autocorrelation Estimation for IRS-Aided Wireless Communications Based on Power Measurements

no code implementations17 Oct 2023 Ge Yan, Lipeng Zhu, Rui Zhang

Intelligent reflecting surface (IRS) can bring significant performance enhancement for wireless communication systems by reconfiguring wireless channels via passive signal reflection.

GNFactor: Multi-Task Real Robot Learning with Generalizable Neural Feature Fields

1 code implementation31 Aug 2023 Yanjie Ze, Ge Yan, Yueh-Hua Wu, Annabella Macaluso, Yuying Ge, Jianglong Ye, Nicklas Hansen, Li Erran Li, Xiaolong Wang

To incorporate semantics in 3D, the reconstruction module utilizes a vision-language foundation model ($\textit{e. g.}$, Stable Diffusion) to distill rich semantic information into the deep 3D voxel.
