RUAD: unsupervised anomaly detection in HPC systems

no code implementations28 Aug 2022 Martin Molan, Andrea Borghesi, Daniele Cesarini, Luca Benini, Andrea Bartolini

However, current state-of-the-art (SoA) approaches to anomaly detection are supervised and semi-supervised, so they require a human-labelled dataset with anomalies - this is often impractical to collect in production HPC systems.

Machine Learning for Combinatorial Optimisation of Partially-Specified Problems: Regret Minimisation as a Unifying Lens

no code implementations20 May 2022 Stefano Teso, Laurens Bliek, Andrea Borghesi, Michele Lombardi, Neil Yorke-Smith, Tias Guns, Andrea Passerini

The challenge is to learn them from available data, while taking into account a set of hard constraints that a solution must satisfy, and that solving the optimisation problem (esp.

Deep Learning for Virus-Spreading Forecasting: a Brief Survey

no code implementations3 Mar 2021 Federico Baldo, Lorenzo Dall'Olio, Mattia Ceccarelli, Riccardo Scheda, Michele Lombardi, Andrea Borghesi, Stefano Diciotti, Michela Milano

Injective Domain Knowledge in Neural Networks for Transprecision Computing

1 code implementation24 Feb 2020 Andrea Borghesi, Federico Baldo, Michele Lombardi, Michela Milano

Machine Learning (ML) models are very effective in many learning tasks, due to the capability to extract meaningful information from large data sets.

Combining Learning and Optimization for Transprecision Computing

2 code implementations24 Feb 2020 Andrea Borghesi, Giuseppe Tagliavini, Michele Lombardi, Luca Benini, Michela Milano

The ML model learns the relation between variables precision and the output error; this information is then embedded in the MP focused on minimizing the number of bits.
