Milan Tenn
We prove the conjecture of Donnelly et al. that a certain class of Littlewood-Richardson tableaux are equinumerous with peakless Motzkin paths of length . Furthermore, we constr…
CEAA: A Cognitive Embodied Agents Architecture for Interactive Computing Systems
Aimilios Hadjiliasi, Louis Nisiotis
The development of embodied Intelligent Virtual Agents (IVAs) that have cognitive capabilities in real-time interactive virtual environments remains a challenge, even with today's…
From Prompt to Service: An SLM-Based Agent Orchestration Gateway for AI-Driven Virtual Worlds
Louis Nisiotis, Aimilios Hadjiliasi
As generative AI capabilities expand, AI-driven virtual worlds face a growing architectural challenge. Users interact through in-world interfaces in multimodal ways, yet their requ…
A Comparative Assessment of Technology Acceptance and Learning Outcomes in Computer-based versus VR-based Pedagogical Agents
Aimilios Hadjiliasi, Louis Nisiotis, Irene Polycarpou
As educational technology evolves, the potential of Pedagogical Agents (PAs) in supporting education is extensively explored. Typically, research on PAs has primarily focused on co…
