Highly skewed long-tail item distribution is very common in recommendation systems. It significantly hurts model performance on tail items. To improve tail-item recommendation, we conduct research to transfer knowledge from head items to tail items, leveraging the rich user feedback in head items and the semantic connections between head and tail items. Specifically, we propose a novel dual transfer learning framework that jointly learns the knowledge transfer from both model-level and item…

Intent Disentanglement and Feature Self-supervision for Novel Recommendation

This work discloses the mechanism that drives a user’s interaction towards popular or niche items by disentangling her intent into conformity influence (popularity) and personal interests (preference) and presents a unified end-to-end framework to simultaneously optimize accuracy and novelty targets based on the disentangled intent of popularity and that of preference.

Addressing Popularity Bias in Citizen Science

A novel re-ranking model is proposed, based on the lift measure used in machine learning, which considers item co-occurrence as well as popularity for enhancing long tail recommendations for enhancing “long-tail” item recommendation that can be applied to any recommendation system.

UFNRec: Utilizing False Negative Samples for Sequential Recommendation

This work designs a teacher model to provide soft labels for false negative samples and design a consistency loss to regularize the predictions of these samples from the student model and the teacher model, and is the first work to utilizefalse negative samples instead of simply removing them for the sequential recommendation.

Self-Supervised Hypergraph Transformer for Recommender Systems

SHT, a novel Self-Supervised Hypergraph Transformer framework (SHT) which augments user representations by exploring the global collaborative relationships in an explicit way, is proposed for data augmentation over the user-item interaction graph, so as to enhance the robustness of recommender systems.

Harmless Transfer Learning for Item Embeddings

This work proposes a harmless transfer learning framework that limits the impact of the potential biases in both the definition and optimization of the transfer loss, and uses a lexicographic optimization framework to efficiently incorporate the information of thetransfer loss without hurting the minimization of the main prediction loss function.
