🚀 Just released a new tool for the neuroscience and Topological Data Analysis communities!
🔗 github.com/gdisarra/top...

The topology-degree repository provides code and methods to quantify the topology in high-dimensional data using persistent homology.

A computation that took us over 8 hours now only takes 15 seconds with tropical geometry! Very excited that Oskar Henriksson will join the algebra in data analysis (AIDA) group @mpicbg.bsky.social @tudresden.bsky.social

My paper with Luis Scoccola and @haharrington.bsky.social were accepted to present in ICML 2025 🥳🥳
We use gradient descent to solve a fundamental problem in computational topology: Compute a topologically good cover of a dataset. It improves Mapper and persistent homology!

Cover Learning for Large-Scale Topology Representation
Classical unsupervised learning methods like clustering and linear dimensionality reduction parametrize large-scale geometry when it is discrete or linear, while more modern methods from manifold lear...

Hi, this is my new professional account :)
I'm a mathematician working on geometry and topology of data. Recently I'm focused on Bobrowski-Skraba's universal statistical law of persistent homology, and also neuroscience applications - toroidal grid cell topology.

어떤 차별은 공기처럼 존재한다. 어느새 소수자를 에워싼다. 소수자는 차별의 시선을 스스로 내면화하기에 이른다. 모욕에 가까운 차별을 당해도 피해망상은 아닐까 자기검열하는 식이다. 섣불리 부당하다고 말했다가는 혐오의 표적이 될 수도 있다. 결코 사소할 수 없는 소수자의 감정을 캐시 박 홍 UC버클리대 교수는 ‘마이너 필링스(minor feelings·소수적 감정)’라고 이름 붙였다.
