What does an anomaly score represent in Elasticsearch machine learning anomaly detection?

AThe average value of the detected anomalies

BThe total number of data points processed by the job

CThe likelihood that a data point is unusual compared to normal patterns

DThe time taken to run the anomaly detection job

Step-by-Step Solution

Solution:

Step 1: Understand anomaly score meaning
An anomaly score measures how unusual a data point is compared to expected behavior.
Step 2: Relate to Elasticsearch ML output
Elasticsearch assigns higher scores to points that deviate more from normal patterns.
Final Answer:
The likelihood that a data point is unusual compared to normal patterns -> Option C
Quick Check:
Anomaly score = Unusualness likelihood [OK]

Quick Trick: Anomaly score shows how strange a data point is [OK]
