Usable XAI: 10 Strategies Towards Exploiting Explainability in the LLM Era

1 code implementation13 Mar 2024 Xuansheng Wu, Haiyan Zhao, Yaochen Zhu, Yucheng Shi, Fan Yang, Tianming Liu, Xiaoming Zhai, Wenlin Yao, Jundong Li, Mengnan Du, Ninghao Liu

Therefore, in this paper, we introduce Usable XAI in the context of LLMs by analyzing (1) how XAI can benefit LLMs and AI systems, and (2) how LLMs can contribute to the advancement of XAI.

DPPA: Pruning Method for Large Language Model to Model Merging

1 code implementation5 Mar 2024 Yaochen Zhu, Rui Xia, Jiajun Zhang

In this paper, we introduce a dual-stage method termed Dynamic Pruning Partition Amplification (DPPA), devised to tackle the challenge of merging complex fine-tuned models.

Collaborative Large Language Model for Recommender Systems

1 code implementation2 Nov 2023 Yaochen Zhu, Liang Wu, Qi Guo, Liangjie Hong, Jundong Li

We first extend the vocabulary of pretrained LLMs with user/item ID tokens to faithfully model user/item collaborative and content semantics.

Knowledge Editing for Large Language Models: A Survey

no code implementations24 Oct 2023 Song Wang, Yaochen Zhu, Haochen Liu, Zaiyi Zheng, Chen Chen, Jundong Li

Afterward, we provide an innovative taxonomy of KME techniques based on how the new knowledge is introduced into pre-trained LLMs, and investigate existing KME strategies while analyzing key insights, advantages, and limitations of methods from each category.

Path-Specific Counterfactual Fairness for Recommender Systems

1 code implementation5 Jun 2023 Yaochen Zhu, Jing Ma, Liang Wu, Qi Guo, Liangjie Hong, Jundong Li

But since sensitive features may also affect user interests in a fair manner (e. g., race on culture-based preferences), indiscriminately eliminating all the influences of sensitive features inevitably degenerate the recommendations quality and necessary diversities.

Personality-aware Human-centric Multimodal Reasoning: A New Task, Dataset and Baselines

no code implementations5 Apr 2023 Yaochen Zhu, Xiangqing Shen, Rui Xia

For another, the multimodal reasoning task emphasized the prediction of future states and behaviors but often neglected the incorporation of individual personality traits.

Causal Inference in Recommender Systems: A Survey of Strategies for Bias Mitigation, Explanation, and Generalization

1 code implementation3 Jan 2023 Yaochen Zhu, Jing Ma, Jundong Li

Traditional RSs estimate user interests and predict their future behaviors by utilizing correlations in the observational historical activities, their profiles, and the content of interacted items.

Mutually-Regularized Dual Collaborative Variational Auto-encoder for Recommendation Systems

1 code implementation21 Nov 2022 Yaochen Zhu, Zhenzhong Chen

However, since latent item variables are not modeled in UAE, it is difficult to utilize the widely available item content information when ratings are sparse.

Deep Deconfounded Content-based Tag Recommendation for UGC with Causal Intervention

1 code implementation28 May 2022 Yaochen Zhu, Xubin Ren, Jing Yi, Zhenzhong Chen

We first establish a causal graph to represent the relations among uploader, UGC, and tag, where the uploaders are identified as confounders that spuriously correlate UGC and tag selections.

Deep Causal Reasoning for Recommendations

1 code implementation6 Jan 2022 Yaochen Zhu, Jing Yi, Jiayi Xie, Zhenzhong Chen

As with all observational studies, hidden confounders, which are factors that affect both item exposures and user ratings, lead to a systematic bias in the estimation.

Cross-modal Variational Auto-encoder for Content-based Micro-video Background Music Recommendation

no code implementations15 Jul 2021 Jing Yi, Yaochen Zhu, Jiayi Xie, Zhenzhong Chen

Moreover, the multimodal information is fused by the product-of-experts (PoE) principle, where the semantic information in visual and textual modalities of the micro-video are weighted according to their variance estimations such that the modality with a lower noise level is given more weights.

Variational Bandwidth Auto-encoder for Hybrid Recommender Systems

1 code implementation17 May 2021 Yaochen Zhu, Zhenzhong Chen

Moreover, by considering the fusion of collaborative and feature variables as a virtual communication channel from an information-theoretic perspective, we introduce a user-dependent channel to dynamically control the information allowed to be accessed from the feature embeddings.
