About me
I’m a PhD student at the Jagiellonian University, working on machine learning with the GMUM group under supervision of Prof. Jacek Tabor. My main research interests are centered around the issue of efficiency in deep learning, highlighting the following questions in particular:
- Continual Learning – how to remember the past and reuse it efficiently when learning from a stream of data.
- Conditional Computation – how to adapt the computing power of the model to a given example.
- Generative Models – how to perform weakly supervised conditional generation and adapt existing models for conditional generation.
- Reinforcement Learning – how to increase the sample efficiency and leverage privilged data during training.
- Imitation Learning – how to combat distribution shift when learning from expert data.
