From noise to signal
Most log lines are reprints. The useful ones are the reprints that changed.

Most log lines are reprints. The useful ones are the reprints that changed.
A good log model starts by admitting that uniqueness is rare. Template mining finds the stable sentence. Clustering groups the reprints. Anomaly detection watches the groups, not the individual characters.
We keep the raw event. Always. Signal is a view, not a delete. Engineers must be able to drop from the sentence to the line that proved it.
That is why LogAI never hides the stream. It simply refuses to make the stream the homepage of an incident.
