E Pluribus Unum: Guidelines on Multi-Objective Evaluation of Recommender Systems

1 code implementation20 Apr 2023 Patrick John Chia, Giuseppe Attanasio, Jacopo Tagliabue, Federico Bianchi, Ciro Greco, Gabriel de Souza P. Moreira, Davide Eynard, Fahd Husain

Recommender Systems today are still mostly evaluated in terms of accuracy, with other aspects beyond the immediate relevance of recommendations, such as diversity, long-term user retention and fairness, often taking a back seat.

EvalRS: a Rounded Evaluation of Recommender Systems

1 code implementation12 Jul 2022 Jacopo Tagliabue, Federico Bianchi, Tobias Schnabel, Giuseppe Attanasio, Ciro Greco, Gabriel de Souza P. Moreira, Patrick John Chia

Much of the complexity of Recommender Systems (RSs) comes from the fact that they are used as part of more complex applications and affect user experience through a varied range of user interfaces.

Hybrid Session-based News Recommendation using Recurrent Neural Networks

no code implementations22 Jun 2020 Gabriel de Souza P. Moreira, Dietmar Jannach, Adilson Marques da Cunha

We describe a hybrid meta-architecture -- the CHAMELEON -- for session-based news recommendation that is able to leverage a variety of information types using Recurrent Neural Networks.

On the Importance of News Content Representation in Hybrid Neural Session-based Recommender Systems

2 code implementations12 Jul 2019 Gabriel de Souza P. Moreira, Dietmar Jannach, Adilson Marques da Cunha

A particular problem in that context is that online readers are often anonymous, which means that this personalization can only be based on the last few recorded interactions with the user, a setting named session-based recommendation.

News Session-Based Recommendations using Deep Neural Networks

3 code implementations31 Jul 2018 Gabriel de Souza P. Moreira, Felipe Ferreira, Adilson Marques da Cunha

This architecture is composed of two modules, the first responsible to learn news articles representations, based on their text and metadata, and the second module aimed to provide session-based recommendations using Recurrent Neural Networks.
