If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://bemind.gitbook.io/neural/neuralprophet/rukovodstva-po-funkciyam/pryamaya-vizualizaciya-vo-vremya-obucheniya.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
