Overview of this book

From data wrangling through to translating text, you can accomplish this and more with the artificial intelligence and machine learning services available on AWS. With this book, you’ll work through hands-on exercises and learn to use these services to solve real-world problems. You’ll even design, develop, monitor, and maintain machine and deep learning models on AWS. The book starts with an introduction to AI and its applications in different industries, along with an overview of AWS artificial intelligence and machine learning services. You’ll then get to grips with detecting and translating text with Amazon Rekognition and Amazon Translate. The book will assist you in performing speech-to-text with Amazon Transcribe and Amazon Polly. Later, you’ll discover the use of Amazon Comprehend for extracting information from text, and Amazon Lex for building voice chatbots. You will also understand the key capabilities of Amazon SageMaker such as wrangling big data, discovering topics in text collections, and classifying images. Finally, you’ll cover sales forecasting with deep learning and autoregression, before exploring the importance of a feedback loop in machine learning. By the end of this book, you will have the skills you need to implement AI in AWS through hands-on exercises that cover all aspects of the ML model life cycle.

Performing inference through Batch Transform

In this section, we will classify (in batch mode) a few images that form part of the test dataset. Since we want to classify more than one image at a time, we will create a Batch Transform job. Please refer to Chapter 8, Creating Machine Learning Inference Pipelines, to learn about when and where Batch Transform jobs are used and how they work.

Before we create a Batch Transform job, we need to provision the trained model.

In the following code snippet, we are going to do the following:

  1. We will create a trained model by calling the create_model() function of the SageMaker service (boto3, the AWS SDK for Python, is used to provision a low-level interface to the SageMaker service).
  2. We will pass a Docker image of the image classification algorithm and the path to the trained model to this function:
info = sage.describe_training_job(TrainingJobName...
