SegRNN: Segment Recurrent Neural Network for Long-Term Time Series Forecasting

2 code implementations22 Aug 2023 Shengsheng Lin, Weiwei Lin, Wentai Wu, Feiyu Zhao, Ruichao Mo, Haotong Zhang

To address these issues, we propose two novel strategies to reduce the number of iterations in RNNs for LTSF tasks: Segment-wise Iterations and Parallel Multi-step Forecasting (PMF).

PETformer: Long-term Time Series Forecasting via Placeholder-enhanced Transformer

no code implementations9 Aug 2023 Shengsheng Lin, Weiwei Lin, Wentai Wu, SongBo Wang, Yongxiang Wang

Recently, the superiority of Transformer for long-term time series forecasting (LTSF) tasks has been challenged, particularly since recent work has shown that simple models can outperform numerous Transformer-based approaches.

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.
