A Secure Sequencer and Data Availability Committee for Rollups (Extended Version)
Margarita Capretto, Martín Ceresa, Antonio Fernández Anta +2
Blockchains face a scalability limitation, partly due to the throughput limitations of consensus protocols, especially when aiming to obtain a high degree of decentralization. Laye…
Detecting and Classifying Outliers in Big Functional Data
Oluwasegun Taiwo Ojo, Antonio Fernández Anta, Rosa E. Lillo +1
We propose two new outlier detection methods, for identifying and classifying different types of outliers in (big) functional data sets. The proposed methods are based on an existi…
A Novel Hyperparameter-free Approach to Decision Tree Construction that Avoids Overfitting by Design
Rafael Garcia Leiva, Antonio Fernandez Anta, Vincenzo Mancuso +1
Decision trees are an extremely popular machine learning technique. Unfortunately, overfitting in decision trees still remains an open issue that sometimes prevents achieving good…
A Measurement-based Analysis of the Energy Consumption of Data Center Servers
Jordi Arjona, Angelos Chatzipapas, Antonio Fernandez Anta +1
Energy consumption is a growing issue in data centers, impacting their economic viability and their public image. In this work we empirically characterize the power and energy cons…
Measuring the Impact of Adversarial Errors on Packet Scheduling Strategies
Antonio Fernández Anta, Chryssis Georgiou, Dariusz R. Kowalski +2
In this paper we explore the problem of achieving efficient packet transmission over unreliable links with worst case occurrence of errors. In such a setup, even an omniscient offl…
Bisection (Band)Width of Product Networks with Application to Data Centers
Jordi Arjona Aroca, Antonio Fernández Anta
The bisection width of interconnection networks has always been important in parallel computing, since it bounds the amount of information that can be moved from one side of a netw…
Failure Detectors in Homonymous Distributed Systems (with an Application to Consensus)
Sergio Arévalo, Antonio Fernández Anta, Damien Imbs +2
This paper addresses the consensus problem in homonymous distributed systems where processes are prone to crash failures and have no initial knowledge of the system membership ("ho…
