Shilling Attacks against Recommender Systems

This repository contains our implementations for Shilling Attacks against Recommender Systems.

Folder structure:

AUSH: The implementation of AUSH used in our CIKM'20 paper [ACM Library] [arXiv Preprint].
Leg-UP: The implementation of Leg-UP in our TNNLS'22 paper [IEEE Xplore] [arXiv Preprint] and a unified framework for comparing Leg-UP with various attackers including AIA, DCGAN, WGAN, Random Attack, Average Attack, Segment Attack and Bandwagon Attack.
data: Recommendation datasets used in our experiments.

See README.md in each folder for more details.
