ACTING: A Platform for Cyber Ranges Federation
Kyriakos Christou, Maria Michalopoulou, Stefano Taggi +21
Cyber Defence (CD) training requires interoperable cyber-range environments capable of supporting complex, multidomain exercises across distributed infrastructures. This paper pres…
Understanding the Performance Plateau in Text-to-Video Retrieval: A Comprehensive Empirical and Linguistic Analysis
Maria-Eirini Pegia, Dimitrios Stefanopoulos, Björn Þór Jónsson +4
Text-to-video retrieval enables users to find relevant video content using natural language queries, a task that has grown increasingly important with the rapid expansion of online…
CycleCap: Improving VLMs Captioning Performance via Self-Supervised Cycle Consistency Fine-Tuning
Marios Krestenitis, Christos Tzelepis, Konstantinos Ioannidis +5
Visual-Language Models (VLMs) have achieved remarkable progress in image captioning, visual question answering, and visual reasoning. Yet they remain prone to vision-language misal…
Utilizing Large Language Models for Machine Learning Explainability
Alexandros Vassiliades, Nikolaos Polatidis, Stamatios Samaras +5
This study explores the explainability capabilities of large language models (LLMs), when employed to autonomously generate machine learning (ML) solutions. We examine two classifi…
RAG Playground: A Framework for Systematic Evaluation of Retrieval Strategies and Prompt Engineering in RAG Systems
Ioannis Papadimitriou, Ilias Gialampoukidis, Stefanos Vrochidis +2
We present RAG Playground, an open-source framework for systematic evaluation of Retrieval-Augmented Generation (RAG) systems. The framework implements and compares three retrieval…
A Multi-Task Text Classification Pipeline with Natural Language Explanations: A User-Centric Evaluation in Sentiment Analysis and Offensive Language Identification in Greek Tweets
Nikolaos Mylonas, Nikolaos Stylianou, Theodora Tsikrika +2
Interpretability is a topic that has been in the spotlight for the past few years. Most existing interpretability techniques produce interpretations in the form of rules or feature…
Overcome the Fear Of Missing Out: Active Sensing UAV Scanning for Precision Agriculture
Marios Krestenitis, Emmanuel K. Raptis, Athanasios Ch. Kapoutsis +3
This paper deals with the problem of informative path planning for a UAV deployed for precision agriculture applications. First, we observe that the ``fear of missing out'' data le…
Neural Crystals
Sofia Karamintziou, Thanassis Mavropoulos, Dimos Ntioudis +4
We face up to the challenge of explainability in Multimodal Artificial Intelligence (MMAI). At the nexus of neuroscience-inspired and quantum computing, interpretable and transpare…
User Identity Linkage in Social Media Using Linguistic and Social Interaction Features
Despoina Chatzakou, Juan Soler-Company, Theodora Tsikrika +3
Social media users often hold several accounts in their effort to multiply the spread of their thoughts, ideas, and viewpoints. In the particular case of objectionable content, use…
Artificial Disfluency Detection, Uh No, Disfluency Generation for the Masses
T. Passali, T. Mavropoulos, G. Tsoumakas +2
Existing approaches for disfluency detection typically require the existence of large annotated datasets. However, current datasets for this task are limited, suffer from class imb…
LARD: Large-scale Artificial Disfluency Generation
T. Passali, T. Mavropoulos, G. Tsoumakas +2
Disfluency detection is a critical task in real-time dialogue systems. However, despite its importance, it remains a relatively unexplored field, mainly due to the lack of appropri…
Towards Semantic Detection of Smells in Cloud Infrastructure Code
Indika Kumara, Zoe Vasileiou, Georgios Meditskos +5
Automated deployment and management of Cloud applications relies on descriptions of their deployment topologies, often referred to as Infrastructure Code. As the complexity of appl…
Towards Air Quality Estimation Using Collected Multimodal Environmental Data
Anastasia Moumtzidou, Symeon Papadopoulos, Stefanos Vrochidis +6
This paper presents an open platform, which collects multimodal environmental data related to air quality from several sources including official open sources, social media and cit…
