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

no code implementations8 Oct 2022 Xiaomeng Xu, Yun Liu, Weihang Chen, Haocheng Yuan, He Wang, Jing Xu, Rui Chen, Li Yi

To test our method in real scenarios and enable future studies on generalizable visual-tactile tracking, we collect a real visual-tactile in-hand object pose tracking dataset.

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 and applications

no code implementations31 Dec 2020 Xiaomeng Xu

In this paper, we prove that the Stokes matrices, of certain "universal" meromorphic linear system of ordinary differential equations of Poncar\'e rank one, give rise to a family of representations of 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.
