    Excited to share our latest #ICML2026 paper on dataset selection/valuation during the post-training stage, led by @cindy2000_sh, in collaboration with our fantastic colleagues from Meta! The core idea is simple but powerful: treat dataset selection as portfolio allocation. With

    🕛 Excited to share ChronoEarth-492K, a dataset + benchmark for spatiotemporal hyperspectral Earth observation. The goal is simple: make it easier to study not only what is on the Earth’s surface, but also how it changes over time. 🌍 Github Page: github.com/uiuctml/Chrono…

    I know the recent progress in AI from frontier labs is amazing, but let me share one of our recent works that I am really excited about on understanding the role of random projections in approximating influence functions! See Pingbang's detailed thread below 👇 Joint work with

    🚨 New Paper 🚨 A Unified Theory of Random Projection for Influence Functions How large should the projection dimension m be for influence functions to actually work? 👉 We show m is not governed by ambient dimension or any O(log n) bound from classical JL 👉 but by curvature
