Sequential recommendation is a popular task in academic research and close to real-world application scenarios, where the goal is to predict the next action(s) of the user based on his/her previous sequence of actions. In the training process of recommender systems, the loss function plays an essential role in guiding the optimization of recommendation models to generate accurate suggestions for users. However, most existing sequential recommendation tech- niques focus on designing algorithms…

Disentangled Representation for Diversified Recommendations

This work proposes a general diversification framework agnostic to the choice of recommendation algorithm that disentangles the learnt user representation in the recommendation module into category- independent and category-dependent components to differentiate a user's preference over items from two orthogonal perspectives.

Recommender Transformers with Behavior Pathways

The Recommender Transformer (RETR) is built with a novel Pathway Attention mechanism that can dynamically plan the behavior pathway for each user, and sparingly activate the network through this behavior pathway to effectively capture evolving patterns useful for recommendation.



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.

Deep Learning for Sequential Recommendation: Algorithms, Influential Factors, and Evaluations

This survey illustrates the concept of sequential recommendation, proposes a categorization of existing algorithms in terms of three types of behavioral sequence, and summarizes the key factors affecting the performance of DL-based models and conducts corresponding evaluations to demonstrate the effects of these factors.

A novel multi-task framework called Contrastive Learning for Sequential Recommendation (CL4SRec) is proposed, which not only takes advantage of the traditional next item prediction task but also utilizes the contrastive learning framework to derive self-supervision signals from the original user behavior sequences.

Session-based Recommendations with Recurrent Neural Networks

It is argued that by modeling the whole session, more accurate recommendations can be provided by an RNN-based approach for session-based recommendations, and introduced several modifications to classic RNNs such as a ranking loss function that make it more viable for this specific problem.

Fast Greedy MAP Inference for Determinantal Point Process to Improve Recommendation Diversity

This paper proposes a novel algorithm to greatly accelerate the greedy MAP inference for DPP, and shows that this algorithm is significantly faster than state-of-the-art competitors, and provides a better relevance-diversity trade-off on several public datasets.

Contrastive Self-supervised Sequential Recommendation with Robust Augmentation

This paper introduces two informative augmentation operators leveraging item correlations to create high quality views for contrastive learning, and proposes a novel framework, Contrastive Self-supervised Learning for Sequential Recommendation (CoSeRec), on improving model performance, and the robustness against sparse and noisy data.

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.

Recommending Accurate and Diverse Items Using Bilateral Branch Network

This paper generalizes recent proposed bi-lateral branch network in the computer vision commu-nity from image classification to item recommendation and develops an adaptive learning framework for accurate and diversified recommendation.

Time Interval Aware Self-Attention for Sequential Recommendation

This paper proposes TiSASRec (Time Interval aware Self-attention based sequential recommendation), which models both the absolute positions of items as well as the time intervals between them in a sequence, which outperforms various state-of-the-art sequential models on both sparse and dense datasets and different evaluation metrics.
