me

I am a Ph.D. student at the University of Amsterdam at the crossroads between deep learning, computer vision, and neuroscience, supervised by Prof. Arnold Smeulders. My background is in physics with a specialization in neuroscience.

My current research is focused on the problem that we have little knowledge about why Deep Networks perform so well and which properties of the data they use to solve given tasks. We are working on understanding and improving Deep Convolutional Networks through imposing additional structure on them. Carefully structured models can help us to open up the "black-box", so we can draw actual conclusions about what these networks learn, how they learn and when they will fail.
Our most recent effort into this direction is a collaboration with Stéphane Mallat and Edouard Oyallon. This joint work is focused on "Multiscale Hierarchical CNNs", a framework for CNNs whose properties can be mathematically and semantically understood.

I will finish my Ph.D. by the end of 2017 and am currently looking for exciting research positions.
