The system constructs a feature vector fore each data point and k random vectors. After constructions, the system performs a combination of Locality Sensitive Hashing algorithm and Local Outlier Factor (LOF) algorithm on the constructed feature vectors and the constructed k random vectors to compute outlier scores for each data point. The system detects a fraudulent data point based on the outlier scores that indicate consistent degrees."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Computer-implemented method for detecting fraudulent transactions using locality sensitive hashing and locality outlier factor algorithms","description":"Methods and systems for detecting fraudulent data points in a database of a computerized system include receiving, from a user device, a request for detecting one or more fraudulent data points in a d","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11263643","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.
