Towards a Unified Multidimensional Explainability Metric: Evaluating Trustworthiness in AI Models
Georgios Makridis, Georgios Fatouros, Athanasios Kiourtis +4
In this paper, we present a comprehensive framework for assessing the explainability of various XAI methods, such as LIME and SHAP, across multiple datasets and machine learning mo…
An evaluation framework for synthetic data generation models
Ioannis E. Livieris, Nikos Alimpertis, George Domalis +1
Nowadays, the use of synthetic data has gained popularity as a cost-efficient strategy for enhancing data augmentation for improving machine learning models performance as well as…
Explainable Deep Reinforcement Learning: State of the Art and Challenges
George A. Vouros
Interpretability, explainability and transparency are key issues to introducing Artificial Intelligence methods in many critical domains: This is important due to ethical concerns…
Online Co-movement Pattern Prediction in Mobility Data
Andreas Tritsarolis, Eva Chondrodima, Panagiotis Tampakis +1
Predictive analytics over mobility data are of great importance since they can assist an analyst to predict events, such as collisions, encounters, traffic jams, etc. A typical exa…
Online Learning of Event Definitions
Nikos Katzouris, Alexander Artikis, Georgios Paliouras
Systems for symbolic event recognition infer occurrences of events in time using a set of event definitions in the form of first-order rules. The Event Calculus is a temporal logic…
Incremental Learning of Event Definitions with Inductive Logic Programming
Nikos Katzouris, Alexander Artikis, George Paliouras
Event recognition systems rely on properly engineered knowledge bases of event definitions to infer occurrences of events in time. The manual development of such knowledge is a ted…
