Area Under the Receiver-Operator Curve (AU-ROC) The Receiver Operating Characteristic (ROC) curve is a graphical plot that illustrates the diagnostic ability of a binary classifier system as its discrimination threshold is varied. It is created by plotting the True Positive Rate (TPR) against the False Positive Rate (FPR) at various threshold settings. True Positive Rate (TPR), also known as Sensitivity or Recall, is defined as: \text{TPR} = \frac{\text{TP}}{\text{TP} + \text{FN}} False Positive...
KV Caching causes enormous savings in evaluating LLMs. One of the things that fundamentally enbable KV caching to work is: modern LLMs like the GPT series tend to be just Transformer decoders instead of an encoder-decoder architecture. Consider the operations that are involved in a decoder: positional encodings positionwise feedforward netowrks LayerNorms (also positionwise) Masked Self-Attention All operations except the Masked Self-Attention are purely positionwise, the only place where differ...

My old supervisor, Prof. Rainer Nagel, would sometimes ask me whether I am still doing mathematics. The answer. Agentic coding tools are strong enough to essentially set up an entire machine learning experiment and submit the job on Kubernetes. I review code and logic, give specifications, etc. This leaves time for reading papers. I miss giving talks, and I thought it would be nice to write up some things I have been thinking about as material for a seminar talk I can give when I visit old acqua...
Automating Festival Registration with AI Agents How I built an AI-powered system to track swing dance festival registrations and never miss another sold-out event As a swing dancer who travels to festivals across Europe, I was constantly frustrated by missing registration openings. Festivals like Herräng or BalDamn sell out within hours of registration opening, and keeping track of 10+ festivals with different registration dates, times, and timezones was becoming impossible. So I built an AI-pow...
18th to 27th of February 2025. I never planned for any of this to happen. People who don’t know me generally think I have my life mostly together. I have a PhD from one of the strongest math departments in Europe. I have a job that is 100% remote which comes with a lot of freedom. I have friends where I can crash in every corner of Europe. The truth is, I’m just winging it nonstop. I work ridiculously hard. When I was 13, I went to a life-changing summer camp. I talked to a camper a few years ol...
