Hi! I’m Eugenia Elistratova. Cohomology Zero is a blog where I write about machine learning and about math for its own sake.

The name comes from «Группы и теория гомотопий (трэш трейлер)» — a legendary Russian-language trash trailer for a homotopy theory course. We unapologetically nerd out about math here, patiently waiting for the environment to answer: cohomology — zero?..

Current and upcoming series:

  • Transformers from scratch — a step-by-step walk from RNNs with attention to the full Transformer architecture.
  • Generative models — VAEs and friends, with the math worked out carefully.
  • Mathematics — a bit of everything, coming soon.
