MLS-C01 Exam Overview
The AWS Certified Machine Learning – Specialty evaluates the skills of machine learning practitioners and data scientists working on the AWS platform. It covers areas such as data engineering, data mining, modeling and machine learning, tests to assess data analysis skills, data analysis document ML, selecting and training models, and implementing ML solutions. To receive certification, candidates must demonstrate effective AWS ML knowledge and experience through multiple choice and non-multiple choice options.
MLS-C01 Exam Data Engineering
It involves creating and maintaining a pipeline to efficiently collect, transform, and store data for machine learning applications. These processes include defining and managing data sets, ensuring data quality, and integrating data from multiple sources such as databases and data lakes. Effective data applications require expertise in using tools and services such as AWS Glue, Amazon Kinesis, and AWS Lambda to create efficient and reliable applications that support developing and deploying powerful machine learning models.
Exploratory Data Analysis
It is a critical phase in machine learning where data is visually and statistically explored to uncover patterns, anomalies, and relationships. Techniques such as data visualization with tools like Jupyter notebooks and Matplotlib aid in understanding data distributions and correlations. Feature engineering methods like normalization and scaling prepare data for modeling. Evaluating model assumptions and interpreting results using metrics such as ROC curves and confusion matrices are key in guiding subsequent modeling decisions.
Machine Learning Implementation and Operations (20%)
Modeling in machine learning involves transforming business problems into mathematical models that can be solved using algorithms. This site focuses on selecting the appropriate model based on data characteristics and business objectives. Model training uses techniques such as supervised or unsupervised learning to fit data and make predictions. Optimization techniques such as hyperparameter tuning can improve model performance. Good modeling enables accurate forecasting and forecasting in areas ranging from finance to healthcare, enabling informed decisions and business results.
