Improving LLMs for Recommendation with Out-Of-Vocabulary Tokens

no code implementations12 Jun 2024 Ting-Ji Huang, Jia-Qi Yang, Chunxu Shen, Kai-Qi Liu, De-Chuan Zhan, Han-Jia Ye

However, since LLMs are typically pretrained on natural language tasks, these in-vocabulary tokens lack the expressive power for distinctive users and items, thereby weakening the recommendation ability even after fine-tuning on recommendation tasks.

JobFormer: Skill-Aware Job Recommendation with Semantic-Enhanced Transformer

no code implementations5 Apr 2024 Zhihao Guan, Jia-Qi Yang, Yang Yang, HengShu Zhu, Wenjie Li, Hui Xiong

Moreover, we adopt a two-stage learning strategy for skill-aware recommendation, in which we utilize the skill distribution to guide JD representation learning in the recall stage, and then combine the user profiles for final prediction in the ranking stage.

COURIER: Contrastive User Intention Reconstruction for Large-Scale Visual Recommendation

1 code implementation8 Jun 2023 Jia-Qi Yang, Chenglei Dai, Dan Ou, Dongshuai Li, Ju Huang, De-Chuan Zhan, Xiaoyi Zeng, Yang Yang

Even if the performance of cross-modal prediction tasks is excellent, it is challenging to provide significant information gain for the downstream models.

Generalized Delayed Feedback Model with Post-Click Information in Recommender Systems

1 code implementation1 Jun 2022 Jia-Qi Yang, De-Chuan Zhan

We propose a generalized delayed feedback model (GDFM) that unifies both post-click behaviors and early conversions as stochastic post-click information, which could be utilized to train GDFM in a streaming manner efficiently.

RID-Noise: Towards Robust Inverse Design under Noisy Environments

1 code implementation7 Dec 2021 Jia-Qi Yang, Ke-Bin Fan, Hao Ma, De-Chuan Zhan

We also define a sample-wise weight, which can be used in the maximum weighted likelihood estimation of an inverse model based on a cINN.

Capturing Delayed Feedback in Conversion Rate Prediction via Elapsed-Time Sampling

1 code implementation6 Dec 2020 Jia-Qi Yang, Xiang Li, Shuguang Han, Tao Zhuang, De-Chuan Zhan, Xiaoyi Zeng, Bin Tong

To strike a balance in this trade-off, we propose Elapsed-Time Sampling Delayed Feedback Model (ES-DFM), which models the relationship between the observed conversion distribution and the true conversion distribution.
