Bradley-Terry Rankings for Recommender Systems Across Dataset Taxonomies

Ekaterina Grishina, Stepan Kuznetsov, Askar Tsyganov +8

The ranking of recommendation algorithms is a challenging problem since model performance is sensitive to dataset characteristics such as sparsity, sequential structure, and scale.…

Cross-Representation Knowledge Transfer for Improved Sequential Recommendations

Artur Gimranov, Viacheslav Yusupov, Elfat Sabitov +4

Transformer architectures, capable of capturing sequential dependencies in the history of user interactions, have become the dominant approach in sequential recommender systems. De…

Position-Aware Sequential Attention for Accurate Next Item Recommendations

Timur Nabiev, Evgeny Frolov

Sequential self-attention models usually rely on additive positional embeddings, which inject positional information into item representations at the input. In the absence of posit…

Benefiting from Negative yet Informative Feedback by Contrasting Opposing Sequential Patterns

Veronika Ivanova, Evgeny Frolov, Alexey Vasilev

We consider the task of learning from both positive and negative feedback in a sequential recommendation scenario, as both types of feedback are often present in user interactions.…

Recommendation Is a Dish Better Served Warm

Danil Gusak, Nikita Sukhorukov, Evgeny Frolov

In modern recommender systems, experimental settings typically include filtering out cold users and items based on a minimum interaction threshold. However, these thresholds are of…

Maximum Impact with Fewer Features: Efficient Feature Selection for Cold-Start Recommenders through Collaborative Importance Weighting

Nikita Sukhorukov, Danil Gusak, Evgeny Frolov

Cold-start challenges in recommender systems necessitate leveraging auxiliary features beyond user-item interactions. However, the presence of irrelevant or noisy features can degr…
