how silly of me to forget that im living a life i once only dreamed of
reward weights on grpo are mostly proportional to the standard deviation of the reward, not the value. this implies that you should consider prenormalizing your rewards to std=1 and then weighting your rewards. kinda blursed

Green fluorescent protein was discovered in a jellyfish. Researchers needed so much material to solve the protein's structure that they invented a "jellyfish cutting machine" capable of extracting GFP from 6,000 jellyfish per day. Osamu Shimomura, who shared a Nobel Prize for…

We estimate that Claude Opus 4.1 has a 50%-time-horizon of around 1 hr 45 min (95% confidence interval of 50 to 195 minutes) on our agentic multi-step software engineering tasks. This estimate is lower than the current highest time-horizon point estimate of around 2 hr 15 min.

RNA is far more than a messenger. Its structures regulate, evolve, and catalyze — carrying out functions DNA and proteins cannot alone. But predicting #RNA structure from sequence is still extremely difficult. In our latest NAR paper, we present a way forward. 🧵 ⤵️
WOAHHH this is SO COOL!!

there is a great trefethen essay about inverse yogiisms... statements that are literally true, but convey something false. what are some for ML? "optimizing a neural network is in a highly non-linear, non-convex, high-dim landscape riddled with saddle points and local minima"?
