Impression-Aware Recommender Systems

no code implementations15 Aug 2023 Fernando B. Pérez Maurera, Maurizio Ferrari Dacrema, Pablo Castells, Paolo Cremonesi

We present a systematic literature review on recommender systems using impressions, focusing on three fundamental angles in research: recommenders, datasets, and evaluation methodologies.

Benchmarking Adaptative Variational Quantum Algorithms on QUBO Instances

no code implementations3 Aug 2023 Gloria Turati, Maurizio Ferrari Dacrema, Paolo Cremonesi

In this paper, we aim to fill this gap by analyzing three Adaptative VQAs: Evolutionary Variational Quantum Eigensolver (EVQE), Variable Ansatz (VAns), already proposed in the literature, and Random Adapt-VQE (RA-VQE), a random approach we introduce as a baseline.

Feature Selection for Classification with QAOA

no code implementations5 Nov 2022 Gloria Turati, Maurizio Ferrari Dacrema, Paolo Cremonesi

The removal of redundant and noisy features can improve both the accuracy and scalability of the trained models.

Towards Feature Selection for Ranking and Classification Exploiting Quantum Annealers

1 code implementation9 May 2022 Maurizio Ferrari Dacrema, Fabio Moroni, Riccardo Nembrini, Nicola Ferro, Guglielmo Faggioli, Paolo Cremonesi

By removing redundant or noisy features, the accuracy of ranking or classification can be improved and the computational cost of the subsequent learning steps can be reduced.

Feature Selection for Recommender Systems with Quantum Computing

1 code implementation11 Oct 2021 Riccardo Nembrini, Maurizio Ferrari Dacrema, Paolo Cremonesi

The promise of quantum computing to open new unexplored possibilities in several scientific fields has been long discussed, but until recently the lack of a functional quantum computer has confined this discussion mostly to theoretical algorithmic papers.

Measuring the User Satisfaction in a Recommendation Interface with Multiple Carousels

no code implementations14 May 2021 Nicolò Felicioni, Maurizio Ferrari Dacrema, Paolo Cremonesi

A crucial aspect of this user interface is that to measure the relevance a new carousel for the user it is not sufficient to account solely for its individual quality.

A Methodology for the Offline Evaluation of Recommender Systems in a User Interface with Multiple Carousels

1 code implementation13 May 2021 Nicolò Felicioni, Maurizio Ferrari Dacrema, Paolo Cremonesi

Hence, we propose an offline evaluation protocol for a carousel setting in which the recommendation quality of a model is measured by how much it improves upon that of an already available set of carousels.

ContentWise Impressions: An Industrial Dataset with Impressions Included

1 code implementation3 Aug 2020 Fernando Benjamín Pérez Maurera, Maurizio Ferrari Dacrema, Lorenzo Saule, Mario Scriminaci, Paolo Cremonesi

In this article, we introduce the ContentWise Impressions dataset, a collection of implicit interactions and impressions of movies and TV series from an Over-The-Top media service, which delivers its media contents over the Internet.

Critically Examining the Claimed Value of Convolutions over User-Item Embedding Maps for Recommender Systems

1 code implementation23 Jul 2020 Maurizio Ferrari Dacrema, Federico Parroni, Paolo Cremonesi, Dietmar Jannach

In recent years, algorithm research in the area of recommender systems has shifted from matrix factorization techniques and their latent factor models to neural approaches.

A Troubling Analysis of Reproducibility and Progress in Recommender Systems Research

1 code implementation18 Nov 2019 Maurizio Ferrari Dacrema, Simone Boglio, Paolo Cremonesi, Dietmar Jannach

In our analysis, we discuss common issues in today's research practice, which, despite the many papers that are published on the topic, have apparently led the field to a certain level of stagnation.

Collaborative Filtering Recommendation Systems

Eigenvalue analogy for confidence estimation in item-based recommender systems

no code implementations31 Aug 2018 Maurizio Ferrari Dacrema, Paolo Cremonesi

Item-item collaborative filtering (CF) models are a well known and studied family of recommender systems, however current literature does not provide any theoretical explanation of the conditions under which item-based recommendations will succeed or fail.
