Sequential three-way decisions with a single hidden layer feedforward neural network

1 code implementation14 Mar 2023 Youxi Wu, Shuhui Cheng, Yan Li, Rongjie Lv, Fan Min

The experimental results verify that STWD-SFNN has a more compact network on structured datasets than other SFNN models, and has better generalization performance than the competitive models.

Deep Forest with Hashing Screening and Window Screening

no code implementations25 Jul 2022 Pengfei Ma, Youxi Wu, Yan Li, Lei Guo, He Jiang, Xingquan Zhu, Xindong Wu

To screen out redundant feature vectors, we introduce a hashing screening mechanism for multi-grained scanning and propose a model called HW-Forest which adopts two strategies, hashing screening and window screening.

OPP-Miner: Order-preserving sequential pattern mining

no code implementations9 Jan 2022 Youxi Wu, Qian Hu, Yan Li, Lei Guo, Xingquan Zhu, Xindong Wu

To discover patterns, existing methods often convert time series data into another form, such as nominal/symbolic format, to reduce dimensionality, which inevitably deviates the data values.
