Execute algorithm
Some algorithms, such as Localization, don't require trained models. You can run no-model-based algorithms using the execute API.
Path and HTTP methods
POST _plugins/_ml/_execute/<algorithm_name>
Example request: Execute localization
The following example uses the Localization algorithm to find subset-level information for aggregate data (for example, aggregated over time) that demonstrates the activity of interest, such as spikes, drops, changes, or anomalies.
