Late Transformer Layers Recode Syntax Canonically: Evidence from Greek Scrambling and Cross-Layer Generalisation
Christos Nikolaos Zacharopoulos, Revekka Kyriakoglou, Chara Tsoukala +1
Probing studies have established that syntactic information is decodable in early and middle transformer layers, but what happens to that information in later layers remains poorly…
Multilingual corpora for the study of new concepts in the social sciences and humanities:
Revekka Kyriakoglou, Anna Pappa
This article presents a hybrid methodology for building a multilingual corpus designed to support the study of emerging concepts in the humanities and social sciences (HSS), illust…
In Machina N400: Pinpointing Where a Causal Language Model Detects Semantic Violations
Christos-Nikolaos Zacharopoulos, Revekka Kyriakoglou
How and where does a transformer notice that a sentence has gone semantically off the rails? To explore this question, we evaluated the causal language model (phi-2) using a carefu…
Decoding Emergent Big Five Traits in Large Language Models: Temperature-Dependent Expression and Architectural Clustering
Christos-Nikolaos Zacharopoulos, Revekka Kyriakoglou
As Large Language Models (LLMs) become integral to human-centered applications, understanding their personality-like behaviors is increasingly important for responsible development…
Pairs of tree dessins, their Shabat polynomials, and monodromy groups
Benjamin Dupont, Revekka Kyriakoglou, Vassilis Metaftsis +2
Coverings of the Riemann sphere by itself, ramified over two points, are given by so-called Shabat polynomials. The correspondence between Grothendieck's dessins d'enfants and Bely…
Développement automatique de lexiques pour les concepts émergents : une exploration méthodologique
Revekka Kyriakoglou, Anna Pappa, Jilin He +5
This paper presents the development of a lexicon centered on emerging concepts, focusing on non-technological innovation. It introduces a four-step methodology that combines human…

Jorge Almeida, Alfredo Costa, Revekka Kyriakoglou +1
We give necessary and sufficient conditions for the group of a rational maximal bifix code to be isomorphic with the -group of , when is recurrent and …
Profinite semigroups
Revekka Kyriakoglou, Dominique Perrin
We present a survey of results on profinite semigroups and their link with symbolic dynamics. We develop a series of results, mostly due to Almeida and Costa and we also include so…
