Jana Zeller

Hi! I'm an ELLIS PhD student at the ETH Max Planck Center for Learning Systems, where I'm fortunate to be supervised by Wieland Brendel and Ryan Cotterell.

Previously, I earned my M.Sc. in Advanced Computer Science from Oxford, supported by a Google DeepMind Scholarship. During my time in Oxford, I worked on visual prompting with Suny Shtedritski and Chrisitan Rupprecht. Before that, I completed my Bachelor at Karlsruhe Institute of Technology. I also spent an exciting summer at Carnegie Mellon University as part of the Robotics Institute Summer Scholars program, exploring efficient architectures for videos with Jonathon Luiten and Deva Ramanan.

Besides research, I enjoy theatre, board games, and baking 🧁
(I am always happy to trade baking recipes and on the hunt for somebody to play set with :D )

Research

I'm interested in computer vision, natural language processing, and how we can combine both to build more intelligent systems, that show similar data efficiency to humans.

Trained an LLM with the knowlede and capabities of a 5th grader. Studied how post-training, in-context learning, and scaling effect performance on out-of-scope tasks.

Can models reason better with intermediate visualizations, akin to human mental imagery? MentisOculi evaluates this across frontier models and finds that visual thoughts do not yet improve reasoning.

We automatically discover visual prompts for CLIP. Interestingly, they look like red circles.

Treating Video as an Image

Preprint, 2022
preprint / poster / video

We speedup video processing by merging frames together and passing them through the same vision model only once.
