AWS Certified Machine Learning – Specialty (MLS-C01)

The AWS Certified Machine Learning – Specialty (MLS-C01) certification is designed for individuals who perform a development or data science role. It validates a candidate’s ability to design, implement, deploy, and maintain machine learning (ML) solutions for given business problems.

As of my knowledge cutoff in September 2021, the exam covers four domains:

1. Data Engineering: 20%
2. Exploratory Data Analysis: 24%
3. Modeling: 36%
4. Machine Learning Implementation and Operations: 20%

Here’s a brief description of each domain:

1. Data Engineering: This domain checks your knowledge and skills in creating data repositories for machine learning, identifying and implementing a data-ingestion solution, identifying and implementing a data-transformation solution.
2. Exploratory Data Analysis: Here you’ll need to sanitize and prepare data for modeling, perform feature engineering, and visualize data for machine learning.
3. Modeling: This covers the knowledge needed to frame business problems as machine learning problems, select the appropriate ML approach, train machine learning models, and perform hyperparameter optimization.
4. Machine Learning Implementation and Operations: In this domain, you’re tested on how to deploy machine learning solutions and operationalize machine learning models. You also need to know how to ensure the operational excellence of machine learning solutions.

To be eligible for this certification, AWS recommends candidates have a background in development or data science, understand basic machine learning concepts, have experience in developing, architecting, or running ML/deep learning workloads on the AWS Cloud. The AWS Machine Learning Path learning resources is a good place to start preparation.

The certification process involves a multiple-choice, multiple-answer exam, and can be taken at a testing center or as an online proctored exam.

As always, please remember to check the official AWS Certification website or other relevant resources for the most recent details, as this information was accurate up to my last training data in September 2021, and AWS may have made updates or changes since then.
