May Developer Challenge - AI Services - Week 5

Developer Advocate
Developer Advocate

Welcome to the last week of the AI Developer Challenge! Thank you so much for your collaboration! I love to see the exchange in the discussion! This week we want to take our model and deploy it to then make predictions using our model.

Now in the real world we would retrain the model with some feature engineering and by using the outcome of our feature importance. But we only have 5 Wednesdays in May and we want to finish the process of training and serving a model with Data Attribute Recommendation (DAR)! You are welcome to try to improve your model share it here as well! Maybe start with feature selection and train a model using only the most important features this time?

Here is what we have to do to deploy a model using DAR:

  1. Use the POST Create Deployment Configuration Regression request. Assign the value of the deploymentExecutableIdRegression (=”70db0a45-c2ab-4525-91c5-0ff763d3784f”) in your environment.  You can also find that ID using the GET List Executables request (make sure to use version 3 of the deployment executable for model template 'bdbcd699-4419-40a5-abb8-e7ad43dde49b’!)

  2. Double check that you are deploying the correct model using the GET List Artifacts request and compare the artifact ids (modelArtifactIdRegression). The scenario ID is still assigned from the previous steps.
  3. After creating the configuration use the POST Deploy Model Regression request to deploy your model. Your status will be UNKNOWN. Check the status using GET Get Deployment Regression details request. Your status should be RUNNING now. With the deployment url you get in the response, you can now query your model.
  4. Go to last folder of the collections DAR API – Inference and open the POST POST Inference Regression request. Assign the deployment id from the previous step to the variable deploymentUrlRegression
  5. Paste the following json into your body to predict avocado prices for the following two data entries:

If you have made it here, GREAT WORK! You have completed 5 weeks of learning about SAP's AI Services! Thank you so much for participating and helping each other out! It is so much fun to be part of this community! We would love to get your feedback on the AI Services! Let us know what your thoughts in the comments!

What you have learned:

  1. Document Information Extraction Premium is a genAI based tool that helps you to extract information from documents. 
  2. You learned how to use the UI as well as the Python SDK!
  3. Data Attribute Recommendation can be applied to different machine learning problems!
  4. You have learned how to upload a dataset and train and deploy a regression model!
  5. We used Postman to implement the end-to-end machine learning workflow!

Additional Information

Week 1 challenge

Week 2 challenge

Week 3 challenge

Week 4 challenge

We have used the AI API Postman collection to train and deploy our model. You can do the same using the AI API Python SDK

You can also connect your DAR instance to SAP AI Launchpad to do the training and serving.

For the inference you can either do a standard REST Call or use the DAR SDK.

My submission for week 5 !

Thanks for all the challenges. For Data Attribute Recommendation, I think I'll need more time to understand the concept and what each API request is doing. I appreciate this opportunity to know this service.




Here's my Submission. Thank you Nora for this challenge around the AI Service

Here is my Week5 Submission. Its new learning on SAP AI Services. Hope to understand in detail on DAR>

Hope to see more challenges on SAP AI




Here is my submission for this week.



Thank you, @noravonthenen, for this awesome learning. I also need to practice a couple of more times with other AI-inference Ops scenarios.





Here's my submission for week 5.


The part of training a model using the API seemed both very complex and very interesting. Made me eager to read a bit more on this subject to try to understand every piece of the puzzle!

Thank you for this challenge, it was super fun!

I can't get the deploymentUrl:


I think I need it to make the query. 😞

@Ruthiel Think you need to wait until the Status is RUNNING.
