An Incremental Update Framework for Online Recommenders with Data-Driven Prior

no code implementations26 Dec 2023 Chen Yang, Jin Chen, Qian Yu, Xiangdong Wu, Kui Ma, Zihao Zhao, Zhiwei Fang, Wenlong Chen, Chaosheng Fan, Jie He, Changping Peng, Zhangang Lin, Jingping Shao

To address the aforementioned issue, we propose an incremental update framework for online recommenders with Data-Driven Prior (DDP), which is composed of Feature Prior (FP) and Model Prior (MP).

Data Contamination Issues in Brain-to-Text Decoding

no code implementations18 Dec 2023 Congchi Yin, Qian Yu, Zhiwei Fang, Jie He, Changping Peng, Zhangang Lin, Jingping Shao, Piji Li

Decoding non-invasive cognitive signals to natural language has long been the goal of building practical brain-computer interfaces (BCIs).

Learning Only On Boundaries: a Physics-Informed Neural operator for Solving Parametric Partial Differential Equations in Complex Geometries

no code implementations24 Aug 2023 Zhiwei Fang, Sifan Wang, Paris Perdikaris

By reformulating the PDEs into boundary integral equations (BIEs), we can train the operator network solely on the boundary of the domain.

Ensemble learning for Physics Informed Neural Networks: a Gradient Boosting approach

no code implementations25 Feb 2023 Zhiwei Fang, Sifan Wang, Paris Perdikaris

While the popularity of physics-informed neural networks (PINNs) is steadily rising, to this date, PINNs have not been successful in simulating multi-scale and singular perturbation problems.

JDRec: Practical Actor-Critic Framework for Online Combinatorial Recommender System

no code implementations27 Jul 2022 Xin Zhao, Zhiwei Fang, Yuchen Guo, Jie He, Wenlong Chen, Changping Peng

A combinatorial recommender (CR) system feeds a list of items to a user at a time in the result page, in which the user behavior is affected by both contextual information and items.

A Physics-Informed Neural Network Framework For Partial Differential Equations on 3D Surfaces: Time-Dependent Problems

no code implementations19 Mar 2021 Zhiwei Fang, Justin Zhang, Xiu Yang

In this paper, we show a physics-informed neural network solver for the time-dependent surface PDEs.

NVIDIA SimNet^{TM}: an AI-accelerated multi-physics simulation framework

no code implementations14 Dec 2020 Oliver Hennigh, Susheela Narasimhan, Mohammad Amin Nabian, Akshay Subramaniam, Kaustubh Tangsali, Max Rietmann, Jose del Aguila Ferrandis, Wonmin Byeon, Zhiwei Fang, Sanjay Choudhry

We present real-world use cases that range from challenging forward multi-physics simulations with turbulence and complex 3D geometries, to industrial design optimization and inverse problems that are not addressed efficiently by the traditional solvers.

Dual Attention Network for Scene Segmentation

12 code implementations CVPR 2019 Jun Fu, Jing Liu, Haijie Tian, Yong Li, Yongjun Bao, Zhiwei Fang, Hanqing Lu

Specifically, we append two types of attention modules on top of traditional dilated FCN, which model the semantic interdependencies in spatial and channel dimensions respectively.
