MultiCBR: Multi-view Contrastive Learning for Bundle Recommendation

1 code implementation28 Nov 2023 Yunshan Ma, Yingzhi He, Xiang Wang, Yinwei Wei, Xiaoyu Du, Yuyangzi Fu, Tat-Seng Chua

It does, however, have two limitations: 1) the two-view formulation does not fully exploit all the heterogeneous relations among users, bundles and items; and 2) the "early contrast and late fusion" framework is less effective in capturing user preference and difficult to generalize to multiple views.

Enhancing Item-level Bundle Representation for Bundle Recommendation

1 code implementation28 Nov 2023 Xiaoyu Du, Kun Qian, Yunshan Ma, Xinguang Xiang

In this paper, we propose a novel approach EBRec, short of Enhanced Bundle Recommendation, which incorporates two enhanced modules to explore inherent item-level bundle representations.

Leveraging Multimodal Features and Item-level User Feedback for Bundle Construction

1 code implementation28 Oct 2023 Yunshan Ma, Xiaohao Liu, Yinwei Wei, Zhulin Tao, Xiang Wang, Tat-Seng Chua

Specifically, we use self-attention modules to combine the multimodal and multi-item features, and then leverage both item- and bundle-level contrastive learning to enhance the representation learning, thus to counter the modality missing, noise, and sparsity problems.

Diffusion Variational Autoencoder for Tackling Stochasticity in Multi-Step Regression Stock Price Prediction

1 code implementation18 Aug 2023 Kelvin J. L. Koa, Yunshan Ma, Ritchie Ng, Tat-Seng Chua

The hierarchical VAE allows us to learn the complex and low-level latent variables for stock prediction, while the diffusion probabilistic model trains the predictor to handle stock price stochasticity by progressively adding random noise to the stock data.

Context-aware Event Forecasting via Graph Disentanglement

1 code implementation12 Aug 2023 Yunshan Ma, Chenchen Ye, Zijian Wu, Xiang Wang, Yixin Cao, Tat-Seng Chua

The task of event forecasting aims to model the relational and temporal patterns based on historical events and makes forecasting to what will happen in the future.

Causal Disentangled Recommendation Against User Preference Shifts

1 code implementation28 Mar 2023 Wenjie Wang, Xinyu Lin, Liuhui Wang, Fuli Feng, Yunshan Ma, Tat-Seng Chua

Inspired by the causal graph, our key considerations to handle preference shifts lie in modeling the interaction generation procedure by: 1) capturing the preference shifts across environments for accurate preference prediction, and 2) disentangling the sparse influence from user preference to interactions for accurate effect estimation of preference.
