Description

We quickly talked about this today.

Basically querying for a combination of evaluations and corresponding hyperparameters is very cumbersome. This might be solved by doing a join on the database and then offering an API to query against.

Description
Example

What I would like to be able to query is:

  • all results from all runs of flow f for task d.
  • predictive_accuracy (I guess this might then be possible) for all runs of flow f on task d

Research direction

Start by locating the REST API entry points and the database records for flows, evaluations, hyperparameters, tasks, and runs. Define how the proposed queries should join those records and what response format covers the two examples; the work is done when both example queries are supported and tested.
