TF4CTR: Twin Focus Framework for CTR Prediction via Adaptive Sample Differentiation

1 code implementation6 May 2024 Honghao Li, Yiwen Zhang, Yi Zhang, Lei Sang, Yun Yang

Specifically, the framework employs the SSEM at the bottom of the model to differentiate between samples, thereby assigning a more suitable encoder for each sample.

AAANE: Attention-based Adversarial Autoencoder for Multi-scale Network Embedding

no code implementations24 Mar 2018 Lei Sang, Min Xu, Shengsheng Qian, Xindong Wu

Existing methods usually adopt a "one-size-fits-all" approach when concerning multi-scale structure information, such as first- and second-order proximity of nodes, ignoring the fact that different scales play different roles in the embedding learning.
