Locations that have few anomalies are indicated in blue; locations with many anomalies are red. Thus you can quickly see the locations that are generating the most anomalies. If your vector layers define regions, counties, or postal codes, you can zoom in for fine details.

 ## How to restart failed {{anomaly-jobs}} [ml-ad-restart-failed-jobs]
 
 If an {{anomaly-job}} fails, try to restart the job by following the procedure described below. If the restarted job runs as expected, then the problem that caused the job to fail was transient and no further investigation is needed. If the job quickly fails after the restart, then the problem is persistent and needs further investigation. In this case, find out which node the failed job was running on by checking the job stats on the **Job management** pane in {{kib}}. Then get the logs for that node and look for exceptions and errors where the ID of the {{anomaly-job}} is in the message to have a better understanding of the issue.

 ## What are the input features used by the model? [faq-features]
 
 All input features are specified by the user, for example, using [diverse statistical functions](https://www.elastic.co/guide/en/machine-learning/current/ml-functions.html) like count or mean over the data of interest.

 ## Does the data used by the model only include customers' data? [faq-data]
 
 Yes. Only the data specified in the {{anomaly-job}} configuration are used for detection.
 
-
 ## What does the model output score represent? How is it generated and calibrated? [faq-output-score]
 
 The ensemble model generates a probability value, which is then mapped to an anomaly severity score between 0 and 100. The lower the probability of observed data, the higher the severity score. Refer to this [advanced concept doc](ml-ad-explain.md) for details. Calibration (also called as normalization) happens on two levels:
 
 1. Within the same metric/partition, the scores are re-normalized “back in time” within the window specified by the `renormalization_window_days` parameter. This is the reason, for example, that both `record_score` and `initial_record_score` exist.
 2. Over multiple partitions, scores are renormalized as described in [this blog post](https://www.elastic.co/blog/changes-to-elastic-machine-learning-anomaly-scoring-in-6-5).

 ## Is the model static or updated periodically? [faq-model-update]
 
 It’s an online model and updated continuously. Old parts of the model are pruned out based on the parameter `model_prune_window` (usually 30 days).

 ## Is the performance of the model monitored? [faq-model-performance]

 ## How to measure the accuracy of the unsupervised {{ml}} model? [faq-model-accuracy]
 
 For each record in a given time series, anomaly detection models provide an anomaly severity score, 95% confidence intervals, and an actual value. This data is stored in an index and can be retrieved using the Get Records API. With this information, you can use standard measures to assess prediction accuracy, interval calibration, and so on. Elasticsearch aggregations can be used to compute these statistics.
 
 The purpose of {{anomaly-detect}} is to achieve the best ranking of periods where an anomaly happened. A practical way to evaluate this is to keep track of real incidents and see how well they correlate with the predictions of {{anomaly-detect}}.

 ## Can the {{anomaly-detect}} model experience model drift? [faq-model-drift]
 
 Elasticsearch’s {{anomaly-detect}} model continuously learns and adapts to changes in the time series. These changes can take the form of slow drifts as well as sudden jumps. Therefore, we take great care to manage the adaptation to changing data characteristics. There is always a fine trade-off between fitting anomalous periods (over-fitting) and not learning new normal behavior. The following are the main approaches Elastic uses to manage this trade-off:
