Mastering Azure Machine Learning. - Second Edition

Overview of this book

Azure Machine Learning is a cloud service for accelerating and managing the machine learning (ML) project life cycle that ML professionals, data scientists, and engineers can use in their day-to-day workflows. This book covers the end-to-end ML process using Microsoft Azure Machine Learning, including data preparation, performing and logging ML training runs, designing training and deployment pipelines, and managing these pipelines via MLOps. The first section shows you how to set up an Azure Machine Learning workspace; ingest and version datasets; as well as preprocess, label, and enrich these datasets for training. In the next two sections, you'll discover how to enrich and train ML models for embedding, classification, and regression. You'll explore advanced NLP techniques, traditional ML models such as boosted trees, modern deep neural networks, recommendation systems, reinforcement learning, and complex distributed ML training techniques - all using Azure Machine Learning. The last section will teach you how to deploy the trained models as a batch pipeline or real-time scoring service using Docker, Azure Machine Learning clusters, Azure Kubernetes Services, and alternative deployment targets. By the end of this book, you’ll be able to combine all the steps you’ve learned by building an MLOps pipeline.

Conventions used

There are a number of text conventions used throughout this book.

Code in text: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "The score.py script is a deployment file that needs to contain an init() and run(batch) method."

A block of code is set as follows:

# increase display of all columns of rows for pandas datasets
pd.set_option('display.max_columns', None)
pd.set_option('display.max_rows', None)
# create pandas dataframe
raw_df = tabdf.to_pandas_dataframe()
raw_df.head()

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

df = df.drop(['Postcode'],axis=1)
df.head()

Any command-line input or output is written as follows:

$ pip install azure-cognitiveservices-personalizer

Bold: Indicates a new term, an important word, or words that you see onscreen. For instance, words in menus or dialog boxes appear in bold. Here is an example: "We can see that the dataset is passed as the titanic named input to the Preprocessing step."
