[All Databricks Machine Learning Associate Questions]

A data scientist is utilizing MLflow Autologging to automatically track their machine learning experiments. After completing a series of runs for the experiment experiment_id, the data scientist wants to identify the run_id of the run with the best root-mean-square error (RMSE).

Which of the following lines of code can be used to identify the run_id of the run with the best RMSE in experiment_id?

AOption A

BOption B

COption C

DOption D

Show Suggested Answer

Suggested Answer: C

To find the run_id of the run with the best root-mean-square error (RMSE) in an MLflow experiment, the correct line of code to use is:

mlflow.search_runs( experiment_id, order_by=['metrics.rmse'] )['run_id'][0]

This line of code searches the runs in the specified experiment, orders them by the RMSE metric in ascending order (the lower the RMSE, the better), and retrieves the run_id of the best-performing run. Option C correctly represents this logic.

Option B looks right for best RMSE!

I might be overthinking it, but I think we need to use a function to get the minimum RMSE, right?

I feel like option B looks familiar, but I can't recall if it specifically targets the best RMSE.

I remember practicing a similar question where we had to sort runs by a metric. I hope it's not too different from that.

I think we need to filter the runs by RMSE, but I'm not sure which option does that correctly.

I've used MLflow before, so I'm confident I can figure this out. I'll carefully read through the question and options to determine the best approach.

Okay, let me think this through step-by-step. I need to find the run with the best RMSE in the specified experiment. The options seem to be showing different MLflow API calls, so I'll need to carefully evaluate each one.

Hmm, I'm a bit unsure about the different MLflow functions and how to use them to find the best run. I'll need to review my notes on that.

This MLflow question is a bit tricky. I'll need to make sure I understand the different functions and how to use them to get the desired result.

Hmm, I'm a bit unsure about this one. I know declarative development is all about using point-and-click tools, but I'm not sure which specific options are the right choices here.

I agree with Lakeesha, Option C looks like the best option to me as well.

But Option C seems to have the most relevant code snippet for identifying the best RMSE.

Option D looks like it's trying to do some sort of black magic. I'm going to have to go with Option C, it's the only one that doesn't make me feel like I'm about to summon a demon.

Hold on, are we sure we're not just supposed to stare at the code and try to will the answer into existence? I'm going with Option A, it's the shortest so it must be the best.

Hmm, I'm not sure. Option D seems to have the most complex syntax, so it must be the right answer, right? Just kidding, I think Option B is the way to go.
