Sinopsi

Master the new features in PySpark 3.1 to develop data-driven, intelligent applications. This updated edition covers topics ranging from building scalable machine learning models, to natural language processing, to recommender systems.Machine Learning with PySpark, Second Edition begins with the fundamentals of Apache Spark, including the latest updates to the framework. Next, you will learn the full spectrum of traditional machine learning algorithm implementations, along with natural language processing and recommender systems. YouâÇÖll gain familiarity with the critical process of selecting machine learning algorithms, data ingestion, and data processing to solve business problems. YouâÇÖll see a demonstration of how to build supervised machine learning models such as linear regression, logistic regression, decision trees, and random forests. YouâÇÖll also learn how to automate the steps using Spark pipelines, followed by unsupervised models such as K-means and hierarchical clustering. A section on Natural Language Processing (NLP) covers text processing, text mining, and embeddings for classification. This new edition also introduces Koalas in Spark and how to automate data workflow using Airflow and PySparkâÇÖs latest ML library.After completing this book, you will understand how to use PySparkâÇÖs machine learning library to build and train various machine learning models, along with related components such as data ingestion, processing and visualization to develop data-driven intelligent applicationsWhat you will learn:Build a spectrum of supervised and unsupervised machine learningá algorithmsUse PySparkâÇÖs machine learning library to implement machine learning and recommender systemsáLeverage the new features in PySparkâÇÖs machine learning libraryUnderstand data processing using Koalas in Spark Handle issues around feature engineering, class balance, bias and variance, and cross validation to build optimally fit modelsWho This Book Is ForáData science and machine learning professionals.
