  "title": "The Silhouette Operator: Identifiability of Low-Rank Measures from One-Dimensional Projections",
  "summary": "SME replaces general multivariate nonparametric or deep-learning density estimation with a low-rank empirical measure built by matching 2k one-dimensional projected marginals in Wasserstein distance. It costs an identifiability constraint (the rank-k structure and optimally chosen, non-arbitrary projection directions) plus the complexity of Wasserstein marginal matching, while remaining cheap in compute. It fails when the true distribution is not well approximated by a finite sum of product measures, when projection directions are poorly chosen, or in high-dimensional regimes beyond the moderate settings evaluated.",
  "rationale": "This is a theoretical statistics and density-estimation result outside production LLM inference or training practice, so it is worth monitoring only if the reader's workloads include moderate-dimensional nonparametric density estimation.",
