In accordance with various embodiments, the hierarchical state machine includes one or more non-cyclic directed chains of states representing at least a subset of the label sequences, and transitions weighted based at least in part on the statistical distribution."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Learning the structure of hierarchical extraction models","description":"A hierarchical extraction model for a label hierarchy may be implemented by a weighted hierarchical state machine whose structure and/or weights are determined in part from a statistical distribution ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11295232","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
