My research is focused on investigating and extending the mathematical foundations of equivariant neural networks, with emphasis on Group-equivariant Convolutional Neural Networks (GCNN). Equivariant neural networks are designed to utilize symmetry, when present, to facilitate learning. |

I’m a Ph.D. student in the division of Biomedical Imaging with affiliation to the WASP-AI program. My research’s primary interest is the development and investigation of novel Machine-Learning techniques in biomedical image processing. Specifically, I want to exploit geometrical properties and symmetries of the given image-signals to tackle data-sparsity problems with domain-specific model-design (e.g., Geometrical Deep learning, Graph-CNN, Topology). |
