I am a postdoctoral researcher at Empirical Inference Department, Max Planck Institute for Intelligent Systems working with Bernhard Schölkopf. I work in the field of machine learning (intersection of computer science and statistics). My research topics include (but not limited to)
- Fast (linear runtime) non-parametric statistical tests
- Kernel-based representation of data
- Deep generative modelling of images
- Approximate Bayesian inference
- Please feel free to contact me for a research discussion.
- If you are a student working in a field related to machine learning, and are looking for an internship opportunity (for 2-6 months) at the Empirical Inference department, please contact me.

New preprint: Witnessing Adversarial Training in Reproducing Kernel Hilbert Spaces. In this work, we augment GAN’s loss function with a new term that provides more information about what the generator learns during training.

Our paper titled “Informative Features for Model Comparison” was accepted to NIPS 2018. Given two samples from two candidate models, and a reference sample (observed data), the goal is to design a statistical test to determine which of the two samples is closer to the reference sample. This has an application for comparing two GAN models.
