Predicting municipalities in financial distress: a machine learning approach enhanced by domain expertise

no code implementations11 Feb 2023 Dario Piermarini, Antonio M. Sudoso, Veronica Piccialli

Predicting financial distress in municipalities can be a complex task, as it involves understanding a wide range of factors that can affect a municipality's financial health.

Global Optimization for Cardinality-constrained Minimum Sum-of-Squares Clustering via Semidefinite Programming

1 code implementation19 Sep 2022 Veronica Piccialli, Antonio M. Sudoso

In this paper, we propose a global optimization approach based on the branch-and-cut technique to solve the cardinality-constrained MSSC.

An Exact Algorithm for Semi-supervised Minimum Sum-of-Squares Clustering

1 code implementation30 Nov 2021 Veronica Piccialli, Anna Russo Russo, Antonio M. Sudoso

The minimum sum-of-squares clustering (MSSC), or k-means type clustering, is traditionally considered an unsupervised learning task.

Improving Non-Intrusive Load Disaggregation through an Attention-Based Deep Neural Network

3 code implementations15 Nov 2019 Veronica Piccialli, Antonio M. Sudoso

Energy disaggregation, known in the literature as Non-Intrusive Load Monitoring (NILM), is the task of inferring the power demand of the individual appliances given the aggregate power demand recorded by a single smart meter which monitors multiple appliances.
