Expert-Driven Monitoring of Operational ML Models

no code implementations22 Jan 2024 Joran Leest, Claudia Raibulet, Ilias Gerostathopoulos, Patricia Lago

We propose Expert Monitoring, an approach that leverages domain expertise to enhance the detection and mitigation of concept drift in machine learning (ML) models.

Forming Ensembles at Runtime: A Machine Learning Approach

1 code implementation30 Apr 2021 Tomáš Bureš, Ilias Gerostathopoulos, Petr Hnětynka, Jan Pacovský

To tackle this problem, in this paper we propose to recast the ensemble formation problem as a classification problem and use machine learning to efficiently form ensembles at scale.

Characterizing Technical Debt and Antipatterns in AI-Based Systems: A Systematic Mapping Study

no code implementations17 Mar 2021 Justus Bogner, Roberto Verdecchia, Ilias Gerostathopoulos

Results: Our results show that (i) established TD types, variations of them, and four new TD types (data, model, configuration, and ethics debt) are present in AI-based systems, (ii) 72 antipatterns are discussed in the literature, the majority related to data and model deficiencies, and (iii) 46 solutions have been proposed, either to address specific TD types, antipatterns, or TD in general.

Decentralized Optimization of Vehicle Route Planning -- A Cross-City Comparative Study

no code implementations10 Jan 2020 Brionna Davis, Grace Jennings, Taylor Pothast, Ilias Gerostathopoulos, Evangelos Pournaras, Raphael E. Stern

Specifically, this study compares the effects of different underlying urban structures on the overall network performance, and investigates which characteristics of the network make it possible to realize routing improvements using a decentralized optimization router.
