Our paper, “A Theory of Initialization’s Impact on Specialization,” has been accepted to ICLR 2025! openreview.net/forum?id=RQz... We shows how neural network can build specialized and shared representation depending on initialization, this has consequences in continual learning. (1/8)

Thank you to all the organizers, amazing speakers, and EVERYONE who turned out to #standupforscience NYC today! @standupforscience.bsky.social (2nd photo not mine but was shared and was a spectacular view!)

Why do we even have to do this? I wondered the whole time at Stand for Science. 🧪 But it was inspiring to see so many people committed to fighting for truth, science, and justice!

In an unprecedented move, the US National Institutes of Health (NIH) has begun mass terminations of research grants that fund active scientific projects because they no longer meet “agency priorities”…. 🧪 #AcademicSky www.nature.com/articles/d41...

I've created a @gatsbyucl.bsky.social starter pack! Let me know if you’d like to be included, or just jump in to see what we're talking about. Either way, a retweet would be greatly appreciated! 🚀 go.bsky.app/4g6Ro4U go.bsky.app/AErHDon
