Latest Patents

One of John Lim Oh's latest patents is titled "Automated generation of anomaly scenarios for testing machine learned anomaly detection models." This patent describes an anomaly detection system capable of reporting anomalous processes or hosts in a computer network. The system employs machine learning models trained using unsupervised techniques. It assigns observed processes to specific categories based on the file system path of the executed program. The system extracts feature vectors for each process or host from observation records and applies machine learning models to determine an outlier metric for each. Processes or hosts with the highest outlier metrics are reported as detected anomalies for further examination by security analysts. The models can be periodically retrained based on new observation records, allowing them to learn from newly observed data without requiring manual labeling.

Another significant patent by John Lim Oh is "Identifying high-influence features for model-detected anomalies." Similar to his previous work, this patent also focuses on an anomaly detection system that utilizes machine learning models trained with unsupervised techniques. The system categorizes observed processes and extracts feature vectors to determine outlier metrics. The processes or hosts with the highest metrics are flagged as anomalies for security analysts to investigate. This innovation also allows for periodic retraining of the models based on new data.
