Understanding the Machine Learning Process
Before diving into SageMaker’s capabilities, let’s revisit the fundamental stages of machine learning:
- Decision Process: ML algorithms analyze data, labeled or unlabeled, to identify patterns and make predictions.
- Error Function: This function evaluates the model’s accuracy by comparing its predictions to known examples, pinpointing areas for improvement.
- Model Optimization: The algorithm iteratively adjusts its internal parameters based on the error function, striving for ever-increasing accuracy.
SageMaker simplifies these processes, empowering data scientists to efficiently develop and deploy machine learning models.
How Does AWS SageMaker Work?
SageMaker offers a structured approach to the ML lifecycle, encompassing three critical phases:
