Multi-scale Quaternion CNN and BiGRU with Cross Self-attention Feature Fusion for Fault Diagnosis of Bearing

1 code implementation25 May 2024 Huanbai Liu, Fanlong Zhang, Yin Tan, Lian Huang, Yan Li, Guoheng Huang, Shenghong Luo, An Zeng

In this work, we propose a novel FD model by integrating multi-scale quaternion convolutional neural network (MQCNN), bidirectional gated recurrent unit (BiGRU), and cross self-attention feature fusion (CSAFF).

Limits of PageRank-based ranking methods in sports data

no code implementations11 Dec 2020 Yuhao Zhou, Ruijie Wang, Yi-Cheng Zhang, An Zeng, Matúš Medo

We propose a new PageRank variant which outperforms PageRank in all evaluated settings, yet shares its sensitivity to increased randomness in the data.

Enhancing the long-term performance of recommender system

no code implementations1 Apr 2019 Leyang Xue, Peng Zhang, An Zeng

Notably, an optimal parameter n* of ARL existed in long-term recommendation, indicating that there is a trade-off between keeping diversity of item and user's preference to maximize the long-term recommendation accuracy.

Predictability of diffusion-based recommender systems

no code implementations29 Mar 2019 Peng Zhang, Leyang Xue, An Zeng

The results show that the higher recommendation accuracy based on diffusion algorithms can still be achieved by optimizing the way of resource allocation on a density network.
