@random_walker @mmitchell_ai Taking a step back, why do we say ML-based science is in crisis? There are two reasons: First, reproducibility failures in fields adopting ML are systemic—they affect nearly every field that has adopted ML methods. In each case, pitfalls are being independently rediscovered.

[Arvind Narayanan @random_walker]

ML is being rapidly adopted in the sciences, but the gnarly problem of data leakage has led to a reproducibility crisis. In a new paper, @sayashk and I present "model info sheets" to catch leakage by guiding researchers through a series of ~20 questions https://t.co/HPV7tP1f1Z 🧵

Fortran is a well-aged programming language; rock-solid reliability and new support for parallel #programming make it an essential language for next-generation high-performance computing: Modern #Fortran is our Deal of the Day: https://t.co/UwLk32Ovl9 @realmilancurcic

[Arvind Narayanan @random_walker]

There’s a reproducibility crisis brewing in almost every scientific field that has adopted machine learning. On July 28, we’re hosting an online workshop featuring a slate of expert speakers to help you diagnose and fix these problems in your own research: https://t.co/zexYmhkttp
