On the Effectiveness of Unlearning in Session-Based Recommendation

1 code implementation22 Dec 2023 Xin Xin, Liu Yang, Ziqi Zhao, Pengjie Ren, Zhumin Chen, Jun Ma, Zhaochun Ren

On the one hand, these approaches cannot achieve satisfying unlearning effects due to the collaborative correlations and sequential connections between the unlearning item and the remaining items in the session.

Generalizing Few-Shot Named Entity Recognizers to Unseen Domains with Type-Related Features

1 code implementation15 Oct 2023 Zihan Wang, Ziqi Zhao, Zhumin Chen, Pengjie Ren, Maarten de Rijke, Zhaochun Ren

To address this limitation, recent studies enable generalization to an unseen target domain with only a few labeled examples using data augmentation techniques.

FIS-ONE: Floor Identification System with One Label for Crowdsourced RF Signals

1 code implementation12 Jul 2023 Weipeng Zhuo, Ka Ho Chiu, Jierun Chen, Ziqi Zhao, S. -H. Gary Chan, Sangtae Ha, Chul-Ho Lee

To build a prediction model to identify the floor number of a new RF signal upon its measurement, conventional approaches using the crowdsourced RF signals assume that at least few labeled signal samples are available on each floor.

Coarse-to-Fine Knowledge-Enhanced Multi-Interest Learning Framework for Multi-Behavior Recommendation

no code implementations3 Aug 2022 Chang Meng, Ziqi Zhao, Wei Guo, Yingxue Zhang, Haolun Wu, Chen Gao, Dong Li, Xiu Li, Ruiming Tang

More specifically, we propose a novel Coarse-to-fine Knowledge-enhanced Multi-interest Learning (CKML) framework to learn shared and behavior-specific interests for different behaviors.

Robust Binary Models by Pruning Randomly-initialized Networks

1 code implementation3 Feb 2022 Chen Liu, Ziqi Zhao, Sabine Süsstrunk, Mathieu Salzmann

In this paper, we introduce an approach to obtain robust yet compact models by pruning randomly-initialized binary networks.
