Iterative Feedback Network for Unsupervised Point Cloud Registration

1 code implementation9 Jan 2024 Yifan Xie, Boyu Wang, Shiqi Li, Jihua Zhu

In this paper, we propose a novel Iterative Feedback Network (IFNet) for unsupervised point cloud registration, in which the representation of low-level features is efficiently enriched by rerouting subsequent high-level features.

Cross-Modal Information-Guided Network using Contrastive Learning for Point Cloud Registration

1 code implementation2 Nov 2023 Yifan Xie, Jihua Zhu, Shiqi Li, Pengcheng Shi

Specifically, we first incorporate the projected images from the point clouds and fuse the cross-modal features using the attention mechanism.

Data-Driven Min-Max MPC for Linear Systems

no code implementations29 Sep 2023 Yifan Xie, Julian Berberich, Frank Allgower

Designing data-driven controllers in the presence of noise is an important research problem, in particular when guarantees on stability, robustness, and constraint satisfaction are desired.

GDBN: a Graph Neural Network Approach to Dynamic Bayesian Network

no code implementations28 Jan 2023 Yang Sun, Yifan Xie

Identifying causal relations among multi-variate time series is one of the most important elements towards understanding the complex mechanisms underlying the dynamic system.

Linear Data-Driven Economic MPC with Generalized Terminal Constraint

no code implementations2 Dec 2022 Yifan Xie, Julian Berberich, Frank Allgöwer

By employing a generalized terminal constraint with artificial equilibrium, the scheme does not require prior knowledge of the optimal equilibrium.

Less is More: Adaptive Curriculum Learning for Thyroid Nodule Diagnosis

1 code implementation2 Jul 2022 Haifan Gong, Hui Cheng, Yifan Xie, Shuangyi Tan, Guanqi Chen, Fei Chen, Guanbin Li

Thyroid nodule classification aims at determining whether the nodule is benign or malignant based on a given ultrasound image.

Optimal Synthesis of Opacity-Enforcing Supervisors for Qualitative and Quantitative Specifications

no code implementations2 Feb 2021 Yifan Xie, Xiang Yin, ShaoYuan Li

We assume that the system has a "secret" that does not want to be revealed to the intruder.

Opacity Enforcing Supervisory Control using Non-deterministic Supervisors

no code implementations20 Oct 2020 Yifan Xie, Xiang Yin, ShaoYuan Li

Compared with the standard deterministic control mechanism, such a non-deterministic control mechanism can enhance the plausible deniability of the controlled system as the online control decision is a random realization and cannot be implicitly inferred from the control policy.
