    Dust Proposes Pretraining Transformers Without Backpropagation●Dust: Pretraining Transformers Without BackpropagationYhnWarMiddle East27636 min ago

    Researchers at Qlabs have presented Dust, a method for pretraining transformer models without using backpropagation. The work, described in a research note from qlabs.sh, suggests an alternative to the gradient-based training that underpins virtually all modern deep learning. The approach is drawing attention from machine learning practitioners debating whether backprop-free training could reduce the cost or energy demands of building large language models.

    New tool maps the flattest walking routes in San Francisco●Find the flattest route between any two points in SFYhnSportFootball308just now

    A new web tool lets San Francisco residents and visitors find the flattest route between any two points in the city, a boon in a place famous for its steep hills. The project has drawn attention online, with people discussing how useful it could be for cyclists, pedestrians with mobility issues, and anyone tired of climbing SF's notorious gradients.
