Becoming Suspicious Across Borders: Algorithmic Extraterritoriality and AI-Driven Financial Surveillance
Georgios Pavlidis, Savvas Chatzichristofis, Eleni Gavriil
Suspicion is an important, yet elusive concept in anti-money laundering and counter-terrorist financing (AML/CFT), which allows for intervention below the threshold of proof. In it…
Evaluation of Large Language Models for Anomaly Detection in Autonomous Vehicles
Petros Loukas, David Bassir, Savvas Chatzichristofis +1
The rapid evolution of large language models (LLMs) has pushed their boundaries to many applications in various domains. Recently, the research community has started to evaluate th…
6th Place Solution to Google Universal Image Embedding
S. Gkelios, A. Kastellos, S. Chatzichristofis
This paper presents the 6th place solution to the Google Universal Image Embedding competition on Kaggle. Our approach is based on the CLIP architecture, a powerful pre-trained mod…
A distributed, plug-n-play algorithm for multi-robot applications with a priori non-computable objective functions
Athanasios Ch. Kapoutsis, Savvas A. Chatzichristofis, Elias B. Kosmatopoulos
This paper presents a distributed algorithm applicable to a wide range of practical multi-robot applications. In such multi-robot applications, the user-defined objectives of the m…
Investigating the Vision Transformer Model for Image Retrieval Tasks
Socratis Gkelios, Yiannis Boutalis, Savvas A. Chatzichristofis
This paper introduces a plug-and-play descriptor that can be effectively adopted for image retrieval tasks without prior initialization or preparation. The description method utili…
The Lagrangian remainder of Taylor's series, distinguishes time complexities to polynomials or not
Nikolaos P. Bakas, Elias Kosmatopoulos, Mihalis Nicolaou +1
The purpose of this letter is to investigate the time complexity consequences of the truncated Taylor series, known as Taylor Polynomials \cite{bakas2019taylor,Katsoprinakis2011,Ne…
ITSO: A novel Inverse Transform Sampling-based Optimization algorithm for stochastic search
Nikolaos P. Bakas, Vagelis Plevris, Andreas Langousis +1
Optimization algorithms appear in the core calculations of numerous Artificial Intelligence (AI) and Machine Learning methods, as well as Engineering and Business applications. Fol…
