Mitigating Popularity Bias in Sequential Recommendations with Sparse Prior-Regularized Objective

Anton Pembek, Anton Klenitskiy, Alexander Savchenko +1

Popularity bias is a well-known challenge in recommender systems, often leading to the over-exposure of popular items and reduced catalog coverage. In this work, we propose PR-entm…

A Foundation Model for Multimodal Event Sequences in Financial Applications

Nikita Rusakov, Vladislav Meshkov, Konstantin Zorin +4

Predictive modeling is a core component of modern financial services, where a wide range of tasks are traditionally addressed using separate models trained on manually engineered t…

Pre-trained LLMs Meet Sequential Recommenders: Efficient User-Centric Knowledge Distillation

Nikita Severin, Danil Kartushov, Vladislav Urzhumov +8

Sequential recommender systems have achieved significant success in modeling temporal user behavior but remain limited in capturing rich user semantics beyond interaction patterns.…

SplitLight: An Exploratory Toolkit for Recommender Systems Datasets and Splits

Anna Volodkevich, Dmitry Anikin, Danil Gusak +3

Offline evaluation of recommender systems is often affected by hidden, under-documented choices in data preparation. Seemingly minor decisions in filtering, handling repeats, cold-…

Faster and Memory-Efficient Training of Sequential Recommendation Models for Large Catalogs

Maxim Zhelnin, Dmitry Redko, Daniil Volkov +8

Sequential recommendations (SR) with transformer-based architectures are widely adopted in real-world applications, where SR models require frequent retraining to adapt to ever-cha…

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.…

Encode Me If You Can: Learning Universal User Representations via Event Sequence Autoencoding

Anton Klenitskiy, Artem Fatkulin, Daria Denisova +2

Building universal user representations that capture the essential aspects of user behavior is a crucial task for modern machine learning systems. In real-world applications, a use…

Let It Go? Not Quite: Addressing Item Cold Start in Sequential Recommendations with Content-Based Initialization

Anton Pembek, Artem Fatkulin, Anton Klenitskiy +1

Many sequential recommender systems suffer from the cold start problem, where items with few or no interactions cannot be effectively used by the model due to the absence of a trai…

Sparse Autoencoders for Sequential Recommendation Models: Interpretation and Flexible Control

Anton Klenitskiy, Konstantin Polev, Daria Denisova +3

Many current state-of-the-art models for sequential recommendations are based on transformer architectures. Interpretation and explanation of such black box models is an important…
