Here, we introduce a topological approach that reframes physiological brain recordings as a time-varying geometric structure. By quantifying changes in its shape via persistent homology, we extract robust biomarkers that identify seizure onset and end in real time.

@Pseudomanifold @ERC_Research Massive congratulations Bastian!
It’s almost HOLES GPT: Higher Order Learning of Essential Structures with Geometry, @Pseudomanifold and Topology

This is how a proper research dinner goes in Nagoya 🇯🇵

[Ximena Fernández @pi_ene]

@vh_wes Exactly that!

[Ximena Fernández @pi_ene]

It’s happening!

[Ximena Fernández @pi_ene]

@RaphalHOAREAU1 @caeater_7306 Will definitely take a look on that. Thanks for pointing it out!

[Ximena Fernández @pi_ene]

@RaphalHOAREAU1 @caeater_7306 Sounds fascinating! Indeed I recently travelled to Nagoya 🇯🇵 to collaborate with the cosmology research group at the University.

[Ximena Fernández @pi_ene]

@celsius Thanks! I can say it was a hard path to finally achieve it

[Ximena Fernández @pi_ene]

@pgroisma Gracias Patu!

@BanikGurudas Trust in the process, it is hard but it is also gorgeous when you finally understand it. It takes patience and a lot of effort. Good luck!
