Marcel Gutsche, PhD

CTO at rabbitAI | Physics PhD

I build ground-truth systems for computer vision. My background in physics taught me to live with uncertainty β€” to see it not as an error, but as information. The hardest problems are rarely about finding the exact value, but about understanding where uncertainty comes from and how to manage it.

I care less about making models smarter and more about making them honest β€” systems that make their assumptions visible and stay silent when the data has nothing clear to say.

Uncertainty and Decision Tools

Interactive tools for probabilistic thinking, from exploring complex trade-offs to testing your own calibration.

Monte Carlo Decisions

Interactive

Model uncertainty in complex choices using probability distributions. Watch how uncertainty compounds and where your intuition slips.

Calibration Training

Interactive

How confident should you be? Most of us overestimate. This tool shows exactly where your intuition drifts off course.

rabbitAI

At rabbitAI, we build real-world ground truth for computer vision, capturing 3D scenes to make AI systems safer, more explainable, and less naive. My work connects physics, hardware, and machine learning to push the frontier of how machines understand reality.
