Δημοσθένης Ελμάς

At CERTH-ITI, I developed web and mobile applications and built APIs for database transactions and user authentication. I also co-authored two peer-reviewed papers on social-robot-based platforms for diet tracking and childhood-obesity prevention.

For my MSc thesis at Aristotle University of Thessaloniki, I adapted PyTorch implementations of the Informer, Temporal Fusion Transformer, and CSDI diffusion model to forecast wind-farm power output. I modified attention and training procedures and designed a multi-stage training scheme.

In my free time, I’m building a local RAG assistant in C++ with a FAISS index, ONNX Runtime embeddings, and a quantized LLM served through llama.cpp. It’s designed to run without a dedicated GPU and includes multi-turn conversation memory.

I’m also experimenting with a Unity-based tri-dexel machining simulation and reinforcement-learning environment with G-code support. Alongside that project, I’m collaborating with clinical doctors on statistical shape modeling of 3D medical volumes for a research publication.
