Manos Fergadiotis

Currently, I am a Research Enginner at Document Intelligence Centre of Excellence at NCSR "Demokritos" and a Research Assistant at AUEB NLP Group, working on challenging problems in Natural Language Processing.

My research interests focus on Artificial Intelligence, especially Natural Language Processing and particularly:

  • Machine Learning, especially Deep Learning
  • Information Extraction
  • Text Classification, especially Large-Scale Multi-Label Text Classification
  • Few-shot and Zero-shot Learning
  • Information Retrieval for large document collections
  • Transfer Learning (Pre-trained Language Models and Domain Adaptation)
