Feature Selection as Deep Sequential Generative Learning

no code implementations6 Mar 2024 Wangyang Ying, Dongjie Wang, Haifeng Chen, Yanjie Fu

(2) We leverage the trained feature subset utility evaluator as a gradient provider to guide the identification of the optimal feature subset embedding;(3) We decode the optimal feature subset embedding to autoregressively generate the best feature selection decision sequence with autostop.

Knockoff-Guided Feature Selection via A Single Pre-trained Reinforced Agent

1 code implementation6 Mar 2024 Xinyuan Wang, Dongjie Wang, Wangyang Ying, Rui Xie, Haifeng Chen, Yanjie Fu

A deep Q-network, pre-trained with the original features and their corresponding pseudo labels, is employed to improve the efficacy of the exploration process in feature selection.

Self-optimizing Feature Generation via Categorical Hashing Representation and Hierarchical Reinforcement Crossing

1 code implementation8 Sep 2023 Wangyang Ying, Dongjie Wang, Kunpeng Liu, Leilei Sun, Yanjie Fu

Feature generation aims to generate new and meaningful features to create a discriminative representation space. A generated feature is meaningful when the generated feature is from a feature pair with inherent feature interaction.
