Learn Azure Synapse Data Explorer

By: Pericles (Peri) Rocha

Overview of this book

Large volumes of data are generated daily from applications, websites, IoT devices, and other free-text, semi-structured data sources. Azure Synapse Data Explorer helps you collect, store, and analyze such data, and work with other analytical engines, such as Apache Spark, to develop advanced data science projects and maximize the value you extract from data. This book offers a comprehensive view of Azure Synapse Data Explorer, exploring not only the core scenarios of Data Explorer but also how it integrates within Azure Synapse. From data ingestion to data visualization and advanced analytics, you’ll learn to take an end-to-end approach to maximize the value of unstructured data and drive powerful insights using data science capabilities. With real-world usage scenarios, you’ll discover how to identify key projects where Azure Synapse Data Explorer can help you achieve your business goals. Throughout the chapters, you'll also find out how to manage big data as part of a software as a service (SaaS) platform, as well as tune, secure, and serve data to end users. By the end of this book, you’ll have mastered the big data life cycle and you'll be able to implement advanced analytical scenarios from raw telemetry and log data.

Introducing ML into your projects with AutoML

One of the challenges for data scientists and analysts when working with ML is that they need to perform a long series of tests before they can find the optimal parameters to train a model that maximizes its results. From finding and transforming the right features to identifying the algorithms that perform best and tuning their parameters just the right way, this is an extensive task that requires many hours of testing and iteration.

In 2018, Microsoft announced the availability of its AutoML feature in Azure ML during a preview. AutoML works like a recommendation system for ML algorithms: you provide your data, set AutoML to the task you want to achieve (e.g. classification, forecasting, or regression), provide your task parameters (e.g. model metrics or cost constraints), and AutoML will test several different algorithms and parameters until it finds the best model for your data. Then, you can export this model or register it in your...
