cf4 detection system for Transformers

Enterprise systems often produce a large volume of logs to record runtime status and events. Anomaly detection from system logs is crucial for service management and system maintenance. Most existing log-based anomaly detection methods use log event indexes parsed from log data to detect anomalies. Those methods cannot handle unseen log templates and lead to inaccurate anomaly detection…
