About

I'm a machine learning researcher with a strong mathematical background. I finished a Master's degree in machine learning and a Master's degree in mathematics. I graduated from a class for exceptionally gifted students in XIV LO im. Stanisława Staszica and successfully competed in the Polish Mathematical Olympiad and the International Mathematics Competition. I conducted research on commutative algebra and algebraic geometry with Dr. Hab. Joachim Jelisiejew, which resulted in the publication "Irreversibility of structure tensors of modules" (https://doi.org/10.1007/s13348-022-00361-w) and the paper "Iarrobino's decomposition for self-dual modules", available on ArXiv (https://arxiv.org/abs/2405.13829). Now I'm conducting research in machine learning. My specialty field is reinforcement learning. With a group from the Polish Academy of Sciences I co-created the Latent Subgoal Search algorithm (which is yet to be extended). I worked on a proactive cloud solver based on RL for 7bulls.com and developed RL methods for investing in currency pairs for AI Investments. Currently I'm pursuing a PhD at the University of Warsaw in the topic of reinforcement learning. I'm also employed at the IDEAS Research Institute. We conduct research on the topic of communication for multi-agent reinforcement learning. I'm also working on the application of reinforcement learning for the tension regulation in hanger rods with a group from the Polish Academy of Sciences under an NCBR grant.

    Inventing and implementing the Latent Subgoal Search algorithm, a modification of the Subgoal Search algorithm - an algorithm connecting planning and hierarchical reinforcement learning. Our method added the latent representations to the model, as a neural network the Transformer architecture was utilized. Work done as the Master's thesis in machine learning.
