…e training scene asks for two different scale targets depending on which resolution was drawn. GSNorm divides the focal length out. Wide fields of view push it the other way. The cubemap faces have a focal length of 346 px at 756 px wide, a

…the whole thing: Three pieces do all the work: the IDF weight, the saturating term-frequency factor (the part), and the length normalization (the part). Here they are, color-coded — the map for the rest of the piece: Take them one at a time

... dr grpo` is named as partial today too — length normalization is implemented, the doubly-robust bias-correction term the name actually refers to is "left to v0.53.12+," and the schema gate keeps a misconfigured run from silently getting

…e step is why GRPO needs no value network. The repository's is a clipped-ratio surrogate (eps 0.2) with a KL term and a length normalization it can switch off (reported, from reading the file). Verification is split: the e rule is a few lin

For every pure type system, if every legal term has some terminating reduction, then every reduction terminates: the Barendregt–Geuvers–Klop conjecture, with arbitrary sorts, non-functional rules and open contexts. This matters to anyone bu

…ansformer layer is a pair of sublayers (attention, then MLP), and the only question that matters for depth is where the normalization sits relative to the residual add. Post-Norm, the original 2017 layout, normalizes after the add: The stre

One more piece worth naming here because it recurs in the next section: GatedNorm replaces A.X-K1's dual-normalization scheme entirely — a single input-dependent gate applied right after RMSNorm, instead of stacking normalization layers aro
