Joint Identifiability of Cross-Domain Recommendation via Hierarchical Subspace Disentanglement

no code implementations6 Apr 2024 Jing Du, Zesheng Ye, Bin Guo, Zhiwen Yu, Lina Yao

Such a failure may overlook the conditionality between two domains and how it contributes to latent factor disentanglement, leading to negative transfer when domains are weakly correlated.

Distributional Domain-Invariant Preference Matching for Cross-Domain Recommendation

no code implementations4 Sep 2023 Jing Du, Zesheng Ye, Bin Guo, Zhiwen Yu, Lina Yao

Next, we aim to build distributional implicit matchings between the domain-level preferences of two domains.

Adversarially Contrastive Estimation of Conditional Neural Processes

no code implementations23 Mar 2023 Zesheng Ye, Jing Du, Lina Yao

Conditional Neural Processes~(CNPs) formulate distributions over functions and generate function observations with exact conditional likelihoods.

Uncertainty-Aware Pedestrian Trajectory Prediction via Distributional Diffusion

no code implementations15 Mar 2023 Yao Liu, Zesheng Ye, Binghao Li, Lina Yao

In this work, we propose to separately model these two factors by implicitly deriving a flexible distribution that describes complex pedestrians' movements, whereas incorporating predictive uncertainty of individuals with explicit density functions over their future locations.

IDNP: Interest Dynamics Modeling using Generative Neural Processes for Sequential Recommendation

no code implementations9 Aug 2022 Jing Du, Zesheng Ye, Lina Yao, Bin Guo, Zhiwen Yu

In this study, we address these concerns by learning (1) multi-scale representations of short-term interests; and (2) dynamics-aware representations of long-term interests.

See What You See: Self-supervised Cross-modal Retrieval of Visual Stimuli from Brain Activity

no code implementations7 Aug 2022 Zesheng Ye, Lina Yao, Yu Zhang, Sylvia Gustin

Recent studies demonstrate the use of a two-stage supervised framework to generate images that depict human perception to visual stimuli from EEG, referring to EEG-visual reconstruction.
