# Execute algorithm
|
|
|
|
Some algorithms, such as [Localization]({{site.url}}{{site.baseurl}}/ml-commons-plugin/algorithms#localization), don't require trained models. You can run no-model-based algorithms using the `execute` API.
|
|
|
|
## Path and HTTP methods
|
|
|
|
```json
|
|
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.
|
|
|
|
```json
|
|
POST /_plugins/_ml/_execute/anomaly_localization
