Overview of this book

Amazon SageMaker is a fully managed machine learning (ML) service that helps data scientists and ML practitioners manage ML experiments. In this book, you'll use the different capabilities and features of Amazon SageMaker to solve relevant data science and ML problems. This step-by-step guide features 80 proven recipes designed to give you the hands-on machine learning experience needed to contribute to real-world experiments and projects. You'll cover the algorithms and techniques that are commonly used when training and deploying NLP, time series forecasting, and computer vision models to solve ML problems. You'll explore various solutions for working with deep learning libraries and frameworks such as TensorFlow, PyTorch, and Hugging Face Transformers in Amazon SageMaker. You'll also learn how to use SageMaker Clarify, SageMaker Model Monitor, SageMaker Debugger, and SageMaker Experiments to debug, manage, and monitor multiple ML experiments and deployments. Moreover, you'll have a better understanding of how SageMaker Feature Store, Autopilot, and Pipelines can meet the specific needs of data science teams. By the end of this book, you'll be able to combine the different solutions you've learned as building blocks to solve real-world ML problems.

Evaluating the model in Python

In the previous recipes, we have trained the regression model using the Linear Learner algorithm and loaded the model using MXNet and Gluon. After the training step, the model needs to be evaluated, and the results and metric values need to be compared with other models. Model evaluation is a critical part of the ML process as this helps us find the best model, which will be used to perform predictions on future unseen values. This recipe aims to provide a simplified set of steps when evaluating regression models.

With the Python programming language, we will generate the visualization of the regression line over the original scatter plot chart and evaluate the ML model using the relevant metrics (for example, Root Mean Squared Error(RMSE), Mean Squared Error (MSE), and Mean Absolute Error (MAE))
