Cercet\u0103rile recente din cadrul Hub-ului Rom\u00e2n de IA vizeaz\u0103 eficientizarea sistemelor de recomandare, securitatea modelelor de limbaj \u0219i avansul tehnologiilor de sintez\u0103 vocal\u0103 pentru limba rom\u00e2n\u0103.<\/p>\n\n\n\n

Sisteme de Recomandare bazate pe Knowledge Graphs (TRL 3)<\/strong><\/h3>\n\n\n\n

Este propus un sistem de recomandare a re\u021betelor culinare, utiliz\u00e2nd o arhitectur\u0103 hibrid\u0103 pentru a dep\u0103\u0219i limit\u0103rile modelelor bazate exclusiv pe Transformer (cost ridicat, explicabilitate sc\u0103zut\u0103).<\/p>\n\n\n\n

  • Retrieval-Augmented Generation (RAG + KG):<\/strong> LLM-ul interogheaz\u0103 graful de cuno\u0219tin\u021be pentru fapte relevante, inject\u00e2nd tripletele sau subgrafele recuperate direct \u00een prompt pentru a genera r\u0103spunsuri fundamentate (grounded<\/em>).<\/li>\n\n\n\n
  • Graph-Enhanced Training:<\/strong> Include embeddin-uri de graf sau triplete \u00een etapa de fine-tuning pentru a permite modelului s\u0103 \u00eenve\u021be rela\u021biile \u00een mod explicit.<\/li>\n\n\n\n
  • Obiectiv:<\/strong> Crearea unui model compact, eficient \u0219i interpretabil structural pentru recomand\u0103ri de nutri\u021bie \u0219i reducerea risipei alimentare.<\/li>\n<\/ul>\n\n\n\n

    Aceast\u0103 tehnic\u0103 de Proof of Concept vizeaz\u0103 reconstruc\u021bia textului original pornind de la reprezent\u0103rile numerice (embeddings) ale modelelor de tip encoder<\/sup>.<\/p>\n\n\n\n

    • Performan\u021b\u0103:<\/strong> Tehnica de inversare dep\u0103\u0219e\u0219te standardele actuale (SOTA) pe multiple seturi de date \u0219i modele de encodare.<\/li>\n\n\n\n
    • Eficien\u021b\u0103:<\/strong> Metoda de reconstruc\u021bie este optimizat\u0103 la nivel de token, reduc\u00e2nd costurile de generare f\u0103r\u0103 a sacrifica acurate\u021bea recuper\u0103rii.<\/li>\n\n\n\n
    • Aplica\u021bii Critice:<\/strong> Analiza securit\u0103\u021bii (recuperarea propozi\u021biilor din vectori), testarea vulnerabilit\u0103\u021bilor bazelor de date vectoriale \u0219i interpretarea caracteristicilor lingvistice (semantice vs. sintactice) codificate \u00een embedding-uri.<\/li>\n<\/ul>\n\n\n\n
