Are you looking to find out the different performance factors that impact your model rating? Do you want to learn how to refine your model and maintain it in production? This comprehensive course will give you an in-depth insight into the important concepts of how to optimize and refine your model until they meet your specific objectives.  

About the Model Training Deep Dive: Refine and Maintain course 

This course is meant to provide technical audiences and business users with an understanding of the 'Refine' phase of the model training process, as well as how model maintenance works.  

It provides insights into precision vs. recall, the role of 'Validation', the model rating and the different performance factors impacting it, and how you can refine your model until it performs as required to meet your objectives. It will also cover how you can maintain your model in production. 

The Model Training Deep Dive: Refine and Maintain course takes one-hour thirty minutes to complete. At the end, you’ll receive a diploma of completion.
