When using digital certificate, one usually gets signature from some authority, then show the message and signature for verification.

Wanna learn about autodiff and sparsity? Check out our #ICLR2025 blog post with @adrhill.bsky.social and Alexis Montoison. It has everything you need: matrices with lots of zeros, weird compiler tricks, graph coloring techniques, and a bunch of pretty pics! iclr-blogposts.github.io/2025/blog/sp...
A visualization of compressed column evaluation in sparse autodiff. Here, columns 1, 2 and 5 of the matrix (in yellow) have no overlap in their sparsity patterns. Thus, they can be evaluated together by multiplication with a sum of basis vectors (in purple).

Model-free deep RL algorithms like NFSP, PSRO, ESCHER, & R-NaD are tailor-made for games with hidden information (e.g. poker). We performed the largest-ever comparison of these algorithms. We find that they do not outperform generic policy gradient methods, such as PPO. arxiv.org/abs/2502.08938 1/N

@xtimv.bsky.social and I were just discussing this interesting comment in the DeepSeek paper introducing GRPO: a different way of setting up the KL loss. It's a little hard to reason about what this does to the objective. 1/
Also note that, instead of adding KL penalty in the reward, GRPO regularizes by directly adding the KL divergence between the trained policy and the reference policy to the loss, avoiding complicating the calculation of the advantage.
