Transformers are inherently succinct★ 74
Hacker News (AI keywords)53 days agoPaperThis paper studies transformer expressivity through succinctness: how compactly a formalism describes a language. It proves fixed-precision transformers can be exponentially more succinct than LTL and RNNs, and doubly exponentially more succinct than finite automata. The same succinctness makes verification hard, with basic problems such as emptiness and equivalence shown to be EXPSPACE-complete.
How to Stop Shipping Low-Quality RL Environments (with Examples)
Latent Space53 days agoTutorialThe post argues that low-quality RL environments are not harmless infrastructure bugs; they can make models worse by feeding them broken learning signals. Based on years of inspecting trajectories, the author highlights recurring environment and harness failures that teams need to fix. The practical lesson is to debug the training environment, grader, and interaction traces before blaming the model or scaling training.
