I have recently started as a post-doc with Dr. Kyunghyn Cho and Dr. Krzysztof Geras at New York University. I am also a machine learning lead at molecule.one . I obtained my PhD from Jagiellonian University supervised by Prof. Jacek Tabor and co-supervised by Prof. Amos Storkey (University of Edinburgh). I also spent two summers as a visiting student with Prof. Yoshua Bengio.

My email is staszek.jastrzebski (on gmail).

News:

  • Our paper on parameter efficient training of BERT was accepted to ICML 2019!
  • Papers accepted to ICLR 2019, and AISTATS 2019! Also, our preprint on Neural Architecture Search is online.

My main research goal is to understand and improve how deep network generalize. My research interests include:

  • Optimization in Deep Learning
  • Representation Learning
  • Natural Language Processing
  • Computer Aided Drug Design

Co-supervised students:

  • [BSc] Michał Zmysłowski (UW) - Gradient structure and generalization
  • [MSc] Sławomir Mucha - Towards the ImageNet of virtual screening
  • [MSc] Tobiasz Ciepliński - Evaluating generative models in chemistry using docking simulators
  • You? I am always looking for new promising students
  • [Defended, MSc] Tomasz Wesołowski - Relevance of enriching word embeddings in modern deep natural language processing
  • [Defended, MSc] Andrii Krutsylo - Physics aware representation for drug discovery
  • [Defended, BSc] Michał Soboszek - Evaluating word embeddings
  • [Defended, MSc] Jakub Chłędowski - Representation learning for textual entailment
  • [Defended, MSc] Mikołaj Sacha - Meta learning and sharpness of the minima
