Researchers have introduced Hierarchical Partial-Order (HPO) models, an extension of existing rank aggregation techniques designed to handle grouped data with latent hierarchical structures. These models build upon partial-order concepts, allowing for incomparabilities in preferences and enabling principled information sharing across groups. The paper also presents Hierarchical Clustering Partial Order (HCPO) models for unsupervised clustering and demonstrates their effectiveness on various datasets, including LLM agent traces, outperforming existing methods in predictive performance and interpretability.
