Machine Learning Workflow on AWS
A typical machine learning workflow on AWS starts with data collection and preprocessing using services like Amazon S3 and AWS Glue. The next step involves model building and training with Amazon SageMaker, followed by hyperparameter tuning to optimize model performance. Once the model is trained, it is deployed as an endpoint on SageMaker for inference. Finally, AWS services like CloudWatch and SageMaker Model Monitor are used to ensure performance and reliability, with periodic updates to the model as needed.
