Sophia Izokun is a prominent inventor based in New York, NY (US). She has made significant contributions to the field of computer security through her innovative use of machine learning. Her work focuses on reducing false positive alerts, which is a critical challenge in cybersecurity.

Latest Patents

Sophia holds a patent titled "Alert reduction using machine learning scoring." This invention addresses the issue of false positive computer security alerts. The process involves ingesting a dataset of security alerts with their resolution status. The alerts are tokenized, and cardinality is calculated for each tokenized data field. Entropy is also calculated for each tokenized value. A combined token score is generated based on cardinality and entropy, which is then compared against all tokenized fields for the alerts. Adjustments are made to the combined token scores based on these comparisons. Tokens resolved as true positives are excluded, and a generative language model creates an exclusion condition based on the adjusted scores. This exclusion condition is tested against a second dataset to generate a score, which is then presented to the user. Upon user acceptance, the exclusion condition is deployed to filter out false positive alerts.
