Sequential recommendation aims at identifying the next item that is preferred by a user based on their behavioral history. Compared to conventional sequential models that leverage attention mechanisms and RNNs, recent efforts mainly follow two directions for improvement: multi-interest learning and graph convolutional aggregation. Specifically, multi-interest methods such as ComiRec and MIMN, focus on extracting different interests for a user by performing historical item clustering, while…

Improving Transformer-based Sequential Recommenders through Preference Editing

MrTransformer with preference editing (PE) significantly outperforms state-of-the-art sequential recommendation methods in terms of Recall, MRR, and NDCG and finds that long sequences of interactions from which user preferences are harder to extract and represent, benefit most from preference editing.



Controllable Multi-Interest Framework for Recommendation

This paper proposes a novel controllable multi-interest framework for the sequential recommendation, called ComiRec, which captures multiple interests from user behavior sequences, which can be exploited for retrieving candidate items from the large-scale item pool.

Sequential Recommendation with Graph Neural Networks

SURGE integrates different types of preferences in long-term user behaviors into clusters in the graph by re-constructing loose item sequences into tight item-item interest graphs based on metric learning, and dynamically fuses and extracts users' current activated core interests from noisy user behavior sequences.

Multi-Interest Network with Dynamic Routing for Recommendation at Tmall

This paper designs a multi-interest extractor layer based on the recently proposed dynamic routing mechanism, which is applicable for modeling and extracting diverse interests from user's behaviors, and proposes a technique named label-aware attention to help the learning process of user representations.

Session-based Recommendation with Graph Neural Networks

In the proposed method, session sequences are modeled as graph-structured data and GNN can capture complex transitions of items, which are difficult to be revealed by previous conventional sequential methods.

Continuous-Time Sequential Recommendation with Temporal Graph Collaborative Transformer

A new framework Temporal Graph Sequential Recommender (TGSRec) is designed, which advances the self-attention mechanism by adopting a novel collaborative attention and propagate the information learned from TCT layer over the temporal graph to unify sequential patterns and temporal collaborative signals.

Improving Sequential Recommendation with Knowledge-Enhanced Memory Networks

This paper proposes a novel knowledge enhanced sequential recommender that integrates the RNN-based networks with Key-Value Memory Network (KV-MN) and incorporates knowledge base information to enhance the semantic representation of KV- MN.

MRIF: Multi-resolution Interest Fusion for Recommendation

A multi-resolution interest fusion model (MRIF) that is capable to capture the dynamic changes in users' interests at different temporal-ranges, and provides an effective way to combine a group of multi- resolution user interests to make predictions.

Personalized Top-N Sequential Recommendation via Convolutional Sequence Embedding

A Convolutional Sequence Embedding Recommendation Model »Caser» is proposed, which is to embed a sequence of recent items into an image in the time and latent spaces and learn sequential patterns as local features of the image using convolutional filters.

Fusing Similarity Models with Markov Chains for Sparse Sequential Recommendation

Fossil is proposed, a similarity-based method that outperforms alternative algorithms, especially on sparse datasets, and qualitatively that it captures personalized dynamics and is able to make meaningful recommendations.
