MAiDE-up: Multilingual Deception Detection of GPT-generated Hotel Reviews

no code implementations19 Apr 2024 Oana Ignat, Xiaomeng Xu, Rada Mihalcea

Using this dataset, we conduct extensive linguistic analyses to (1) compare the AI fake hotel reviews to real hotel reviews, and (2) identify the factors that influence the deception detection model performance.

Dynamics-Guided Diffusion Model for Robot Manipulator Design

no code implementations23 Feb 2024 Xiaomeng Xu, Huy Ha, Shuran Song

The design objective constructed from the target and predicted interaction profiles provides a gradient to guide the refinement of finger geometry for the task.

JacobiNeRF: NeRF Shaping with Mutual Information Gradients

1 code implementation CVPR 2023 Xiaomeng Xu, Yanchao Yang, Kaichun Mo, Boxiao Pan, Li Yi, Leonidas Guibas

We propose a method that trains a neural radiance field (NeRF) to encode not only the appearance of the scene but also semantic correlations between scene points, regions, or entities -- aiming to capture their mutual co-variation patterns.

Enhancing Generalizable 6D Pose Tracking of an In-Hand Object with Tactile Sensing

1 code implementation8 Oct 2022 Yun Liu, Xiaomeng Xu, Weihang Chen, Haocheng Yuan, He Wang, Jing Xu, Rui Chen, Li Yi

When manipulating an object to accomplish complex tasks, humans rely on both vision and touch to keep track of the object's 6D pose.

AutoGPart: Intermediate Supervision Search for Generalizable 3D Part Segmentation

1 code implementation CVPR 2022 Xueyi Liu, Xiaomeng Xu, Anyi Rao, Chuang Gan, Li Yi

To solve the above issues, we propose AutoGPart, a generic method enabling training generalizable 3D part segmentation networks with the task prior considered.

Representations of quantum groups arising from the Stokes phenomenon

no code implementations31 Dec 2020 Xiaomeng Xu

In this paper we prove that the quantum Stokes matrices of the quantum differential equation at a second order pole give rise to representations of the quantum group $U_q(\frak{gl}_n)$.

Quasi-invariants in characteristic p and twisted quasi-invariants

no code implementations31 Jul 2019 Michael Ren, Xiaomeng Xu

In this paper, we show some partial results and make two conjectures on the Hilbert series of these spaces over fields of positive characteristic.
