A Survey on Hypergraph Neural Networks: An In-Depth and Step-By-Step Guide

no code implementations1 Apr 2024 Sunwoo Kim, Soo Yong Lee, Yue Gao, Alessia Antelmi, Mirko Polato, Kijung Shin

Higher-order interactions (HOIs) are ubiquitous in real-world complex systems and applications, and thus investigation of deep learning for HOIs has become a valuable agenda for the data mining and machine learning communities.

Novel Applications for VAE-based Anomaly Detection Systems

no code implementations26 Apr 2022 Luca Bergamin, Tommaso Carraro, Mirko Polato, Fabio Aiolli

Research also indicates different biases affect deep learning models, leading to social issues such as misrepresentation.

Bayes Point Rule Set Learning

no code implementations11 Apr 2022 Fabio Aiolli, Luca Bergamin, Tommaso Carraro, Mirko Polato

The produced DNF is a set of conjunctive rules, each corresponding to the most specific rule consistent with a part of positive and all negative examples.

Conditioned Variational Autoencoder for top-N item recommendation

1 code implementation16 Apr 2020 Tommaso Carraro, Mirko Polato, Fabio Aiolli

In this paper, we propose a Conditioned Variational Autoencoder (C-VAE) for constrained top-N item recommendation where the recommended items must satisfy a given condition.

LSTM Networks for Data-Aware Remaining Time Prediction of Business Process Instances

1 code implementation10 Nov 2017 Nicolò Navarin, Beatrice Vincenzi, Mirko Polato, Alessandro Sperduti

Predicting the completion time of business process instances would be a very helpful aid when managing processes under service level agreement constraints.

Boolean kernels for collaborative filtering in top-N item recommendation

no code implementations21 Dec 2016 Mirko Polato, Fabio Aiolli

Recent analysis show that collaborative filtering (CF) datasets have peculiar characteristics such as high sparsity and a long tailed distribution of the ratings.

Exploiting sparsity to build efficient kernel based collaborative filtering for top-N item recommendation

1 code implementation17 Dec 2016 Mirko Polato, Fabio Aiolli

The increasing availability of implicit feedback datasets has raised the interest in developing effective collaborative filtering techniques able to deal asymmetrically with unambiguous positive feedback and ambiguous negative feedback.
