Our paper "Towards Sustainable Scientific Machine Learning Fast and Interpretable PDE Solvers via RBF-PIELM" has been accepted at ACM CODS 2025 as oral and archival work !

Excited to share that Iโ€™ll be presenting my research, โ€œTowards Sustainable Scientific Machine Learning: Fast and Interpretable PDE Solvers via RBF-PIELMโ€ at the ACM India Joint International Conference on Data Science (hashtag#cods 2025) !

In the domain of AI for Science, we need PDE solvers that are not just accurate, but also fast and sustainable. Our work introduces Radial Basis Function-based Physics-Informed Extreme Learning Machines (RBF-PIELM), a lightweight, mesh-free alternative to traditional Physics-Informed Neural Networks (PINNs).

  • ๐—ฆ๐˜‚๐˜€๐˜๐—ฎ๐—ถ๐—ป๐—ฎ๐—ฏ๐—ถ๐—น๐—ถ๐˜๐˜†: Using the Green Algorithms Methodology, RBF-PIELM requires significantly less energy and produces substantially lower carbon emissions compared to PINNs. This is a major step towards sustainable scientific computing.

This research lowers the hardware barrier for AI in science, enabling broader accessibility for researchers with limited compute resources.
