AI agents are showing up everywhere in science right now, but deploying them on real research infrastructure presents unique challenges: e.g., federated authentication, restrictive networks, diverse compute, and systems that aren't always up. Paper: doi.org/10.2139/ssrn...

Quite interesting paper that compares various continuous/regression methods for spatial analysis. Not exhaustive, but by using synthetic data, and reproducible workflows, it provides a nice landscape for beginners in the field www.researchgate.net/publication/...

Some brief news. Since February, I have joined PUC-Rio as an Applied Research Scientist, at the ICA lab in the electrical engineering department. Basically working in #AI4Science applications for industry partners. It's nice to be in Rio 🇧🇷

O que ele não fala, é que nós outros países que tem produtividade maior, a escolaridade da população é alta, a taxa de industrialização e automação de processos idem. E detalhe, em TODOS esses a jornada é menor que o 7x0 ( porque no Brasil CLT é exceção, e jornada 44h é coisa de privilegiado)
