I built non-autoregressive decision models with RL a year ago

A long thread on launch language, whether constrained routing is novel, and links to open Jev-like work including OpenDecision.

Highlights

  • 1,362 points. Story URL points at Laya's publisher site, not TypeSafe.
  • Commenters argue constrained choice from predefined options is an established pattern.
  • OpenDecision's author says their project built on Jev-architecture research from a year earlier.
  • A comment links arXiv 2503.23303 as prior art on the architecture Laya's author proposed.

Watch out

Point totals move. Architecture priority claims are commenters' interpretations, not court findings.
