In theory yes, *if trained optimally*. But in practice, do all noise level equally matter? with @annegnx.bsky.social, S Martin & R Gribonval05 Nov 2025 09:03 +0000at://did:plc:7iccorlma4thm34htiswusuc/app.bsky.feed.post/3m4uowrtc422khttps://bsky.app/profile/mathurinmassias.bsky.social/post/3m3whhveanc2qKickstarting our workshop on Flow matching and Diffusion with a talk by Eric Vanden Eijnden on how to optimize learning and sampling in Stochastic Interpolants!

Did you know that the flow matching target you're trying to learn *can only generate training points*? w @quentinbertrand.bsky.social @annegnx.bsky.social @remiemonet.bsky.social 👇👇👇18 Jun 2025 08:08 +0000at://did:plc:7iccorlma4thm34htiswusuc/app.bsky.feed.post/3lrukm2gzw22chttps://bsky.app/profile/mathurinmassias.bsky.social/post/3lnktrczajs2fIt was received quite enthusiastically here so time to share it again!!! Our #ICLR2025 blog post on Flow Matching was published yesterday : https://iclr-blogposts.github.io/2025/blog/conditional-flow-matching/ My PhD student @annegnx.bsky.social will present it tomorrow in ICLR, 👉poster session 4, 3 pm, #549 in Hall 3/2B 👈24 Apr 2025 13:45 +0000at://did:plc:7iccorlma4thm34htiswusuc/app.bsky.feed.post/3lnktrczajs2fhttps://bsky.app/profile/mathurinmassias.bsky.social/post/3lmr3bjhb722bI had a blast giving a summer school on generative models at AI Hub Senegal, in particular flow matching, with @quentinbertrand.bsky.social and @remiemonet.bsky.social Our material is publicly available !!! https://github.com/QB3/SenHubIA2025 ensdelyon.bsky.social14 Apr 2025 07:50 +0000at://did:plc:7iccorlma4thm34htiswusuc/app.bsky.feed.post/3lmr3bjhb722b
