Fast Subspace Identification Method Based on Containerised Cloud Workflow Processing System

no code implementations29 Dec 2021 Runze Gao, Yuanqing Xia, Guan Wang, Liwen Yang, Yufeng Zhan

Subspace identification (SID) has been widely used in system identification and control fields since it can estimate system models only relying on the input and output data by reliable numerical operations such as singular value decomposition (SVD).

Comparison between Time Shifting Deviation and Cross-correlation Methods

no code implementations15 Nov 2021 Zhongwang Pang, Guan Wang, Bo wang, Lijun Wang

It stands in clear contrast to the result of cross-correlation method, whose localization error is 70 m and the standard deviation is 208. 4 m. Compared with cross-correlation method, TSDEV has the same resistance to white noise, but has fewer boundary conditions and better suppression on linear drift or common noise, which leads to more precise TDE results.

On the Statistical Analysis of Complex Tree-shaped 3D Objects

no code implementations17 Oct 2021 Guan Wang, Hamid Laga, Anuj Srivastava

We demonstrate the utility of this framework in comparing, matching, and computing geodesics between biological objects such as neurons and botanical trees.

Graph2Graph Learning with Conditional Autoregressive Models

no code implementations6 Jun 2021 Guan Wang, Francois Bernard Lauze, Aasa Feragen

For such tasks, the main requirement for intermediate representations of the data is to maintain the structure needed for output, i. e., keeping classes separated or maintaining the order indicated by the regressor.

Adaptive N-step Bootstrapping with Off-policy Data

no code implementations1 Jan 2021 Guan Wang, Dong Yan, Hang Su, Jun Zhu

In this work, we point out that the optimal value of n actually differs on each data point, while the fixed value n is a rough average of them.

DCAF: A Dynamic Computation Allocation Framework for Online Serving System

no code implementations17 Jun 2020 Biye Jiang, Pengye Zhang, Rihan Chen, Binding Dai, Xinchen Luo, Yin Yang, Guan Wang, Guorui Zhou, Xiaoqiang Zhu, Kun Gai

These stages usually allocate resource manually with specific computing power budgets, which requires the serving configuration to adapt accordingly.

Early Detection of Retinopathy of Prematurity (ROP) in Retinal Fundus Images Via Convolutional Neural Networks

no code implementations12 Jun 2020 Xin Guo, Yusuke Kikuchi, Guan Wang, Jinglin Yi, Qiong Zou, Rui Zhou

Retinopathy of prematurity (ROP) is an abnormal blood vessel development in the retina of a prematurely-born infant or an infant with low birth weight.

Kalibre: Knowledge-based Neural Surrogate Model Calibration for Data Center Digital Twins

no code implementations29 Jan 2020 Ruihang Wang, Xin Zhou, Linsen Dong, Yonggang Wen, Rui Tan, Li Chen, Guan Wang, Feng Zeng

However, in the context of CFD, each search step requires long-lasting CFD model's iterated solving, rendering these approaches impractical with increased model complexity.
