Effector: A Python package for regional explanations

1 code implementation3 Apr 2024 Vasilis Gkolemis, Christos Diou, Eirini Ntoutsi, Theodore Dalamagas, Bernd Bischl, Julia Herbinger, Giuseppe Casalicchio

Effector implements well-established global effect methods, assesses the heterogeneity of each method and, based on that, provides regional effects.

RHALE: Robust and Heterogeneity-aware Accumulated Local Effects

1 code implementation20 Sep 2023 Vasilis Gkolemis, Theodore Dalamagas, Eirini Ntoutsi, Christos Diou

RHALE quantifies the heterogeneity by considering the standard deviation of the local effects and automatically determines an optimal variable-size bin-splitting.

DALE: Differential Accumulated Local Effects for efficient and accurate global explanations

1 code implementation10 Oct 2022 Vasilis Gkolemis, Theodore Dalamagas, Christos Diou

In this paper, we propose a novel ALE approximation, called Differential Accumulated Local Effects (DALE), which can be used in cases where the ML model is differentiable and an auto-differentiable framework is accessible.

Atrapos: Real-time Evaluation of Metapath Query Workloads

1 code implementation11 Jan 2022 Serafeim Chatzopoulos, Thanasis Vergoulis, Dimitrios Skoutas, Theodore Dalamagas, Christos Tryfonopoulos, Panagiotis Karras

In this paper, we present ATRAPOS, a new approach for the real-time evaluation of metapath query workloads that leverages a combination of efficient sparse matrix multiplication and intermediate result caching.

Simplifying Impact Prediction for Scientific Articles

no code implementations30 Dec 2020 Thanasis Vergoulis, Ilias Kanellos, Giorgos Giannopoulos, Theodore Dalamagas

Moreover, most approaches rely on the existence of rich metadata for each article, a requirement that cannot be adequately fulfilled for a large number of them.

Modeling asset allocation strategies and a new portfolio performance score

no code implementations9 Dec 2020 Apostolos Chalkis, Emmanouil Christoforou, Ioannis Z. Emiris, Theodore Dalamagas

The first concerns crisis detection, which is of prime interest for the public in general and for policy makers in particular because of the significant impact that crises have on the economy.

Ranking Papers by their Short-Term Scientific Impact

no code implementations1 Jun 2020 Ilias Kanellos, Thanasis Vergoulis, Dimitris Sacharidis, Theodore Dalamagas, Yannis Vassiliou

A detailed experimental evaluation on four real citation datasets across disciplines, shows that our approach is more effective than previous work in ranking papers based on their short-term impact.
