PSNet: Fast Data Structuring for Hierarchical Deep Learning on Point Cloud

1 code implementation30 May 2022 Luyang Li, Ligang He, Jinjin Gao, Xie Han

PSNet achieves grouping and sampling at the same time while the existing methods process sampling and grouping in two separate steps (such as using FPS plus kNN).

Variation-Incentive Loss Re-weighting for Regression Analysis on Biased Data

no code implementations14 Sep 2021 Wentai Wu, Ligang He, Weiwei Lin

Both classification and regression tasks are susceptible to the biased distribution of training data.

FedProf: Selective Federated Learning with Representation Profiling

1 code implementation2 Feb 2021 Wentai Wu, Ligang He, Weiwei Lin, Carsten Maple

The results show that the selective behaviour of our algorithm leads to a significant reduction in the number of communication rounds and the amount of time (up to 2. 4x speedup) for the global model to converge and also provides accuracy gain.

An Efficiency-boosting Client Selection Scheme for Federated Learning with Fairness Guarantee

no code implementations3 Nov 2020 Tiansheng Huang, Weiwei Lin, Wentai Wu, Ligang He, Keqin Li, Albert Y. Zomaya

The client selection policy is critical to an FL process in terms of training efficiency, the final model's quality as well as fairness.

Developing an Unsupervised Real-time Anomaly Detection Scheme for Time Series with Multi-seasonality

no code implementations3 Aug 2019 Wentai Wu, Ligang He, Weiwei Lin, Yi Su, Yuhua Cui, Carsten Maple, Stephen Jarvis

In light of this, we have developed a prediction-driven, unsupervised anomaly detection scheme, which adopts a backbone model combining the decomposition and the inference of time series data.
