Tomer Zipori
Playful questions. Rigorous answers.
I build models, experiments, and tools to understand how people—and machines—make sense of the world.
Selected work
Questions with somewhere to go.
Three finished projects where a claim becomes a tool, a workflow, or a picture.
02 · Neural network investigation
Looking for an animal neuron
A controlled experiment inside Gemma that tests whether a strong animal response is really an animal concept.
03 · Model mechanics
What’s Artificial Intelligence all about?
A small hands-on path into the mechanics behind a model.
Completed experiment
Can gradient descent learn around padded zeros?
A BatchNorm implementation detail clearly changed internal activations. Across five paired seeds, its effect on intent-classification macro-F1 was smaller and uncertain.

About me
Let’s talk about statistics, models, and deep neural networks.
My background spans psychology, experimental methods, statistics, data science, and machine learning. I’m facinated by statistics and machine learning. I explore them and turn research questions into models, visual explanations, and even sometimes tools that other people can use.
