Welcome to my personal website! Here I share some of my little projects.

  • Enhancing decision making with RAG chatbot

    Description AI powered virtual assistant speacialized in the AltA methodology (Alternative Analysis) of NATO. It combines Large Language Models (langchain, groq) with Retrieval Augmented Generation (Chroma) to provide responses to specific questions related with the topic that “general purpose” models cannot provide.

  • Prototype-based learning. Part II: LVQ family of models in PyTorch

    Description In my journey to bridge psychology and data science, I discovered Learning Vector Quantization (LVQ) and immediately saw its potential connection to human category learning. This realization led me to dive deeper, implementing LVQ from scratch, initially by coding all the operations using PyTorch, and then by abstracting the optimization and learning processes to fully leverage PyTorch’s features.
