  "title": "Multi-Domain Clustering via Measure Quantization",
  "summary": "Replaces per-domain K-means-style centroid clustering with a shared set of prototypes learned by minimizing a probability metric (Sinkhorn divergence or MMD) between each domain's measure and the prototype measure, with assignment by nearest centroid or optimal transport. Costs are the iterative mini-batch optimization of the divergence (Sinkhorn requires entropic OT computations per batch) plus the implementation complexity of measure-quantization training, though mini-batching keeps memory within a single-GPU budget. It can fail when domains have poorly aligned cluster structures (forcing shared prototypes degrades per-domain fit), when the mini-batch approximation of the divergence is biased at small batch sizes, and when the OT-based assignment couples samples in ways that are expensive or unstable at inference time for very large domains.",
  "rationale": "The method is computationally feasible on constrained infrastructure via its mini-batch strategy, but the quality advantage is asserted without a quantified factor and depends on the workload having genuinely multi-domain data, so it warrants small-scale validation before production adoption.",
