Inhalt: Learn how to use TensorFlow 2.0 to build machine learning and deep learning models with complete examples. The book begins with introducing TensorFlow 2.0 framework and the major changes from its last release. Next, it focuses on building Supervised Machine Learning models using TensorFlow 2.0. It also demonstrates how to build models using customer estimators. Further, it explains how to use TensorFlow 2.0 API to build machine learning and deep learning models for image classification using the standard as well as custom parameters. You'll review sequence predictions, saving, serving, deploying, and standardized datasets, and then deploy these models to production. All the code presented in the book will be available in the form of executable scripts at Github which allows you to try out the examples and extend them in interesting ways.What You'll LearnReview the new features of TensorFlow 2.0Use TensorFlow 2.0 to build machine learning and deep learning models Perform sequence predictions using TensorFlow 2.0Deploy TensorFlow 2.0 models with practical examplesWho This Book Is ForData scientists, machine and deep learning engineers.

Ausgabe: second edition

ISBN: 9781484277768

Inhalt: 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. You'll gain familiarity with the critical process of selecting machine learning algorithms, data ingestion, and data processing to solve business problems. You'll see a demonstration of how to build supervised machine learning models such as linear regression, logistic regression, decision trees, and random forests. You'll 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 PySpark's latest ML library. After completing this book, you will understand how to use PySpark's 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 applications. What you will learn: Build a spectrum of supervised and unsupervised machine learning algorithms. Use PySpark's machine learning library to implement machine learning and recommender systems. Leverage the new features in PySpark's machine learning library. Understand data processing using Koalas in Spark. Handle issues around feature engineering, class balance, bias and variance, and cross validation to build optimally fit models. Who This Book Is For: Data science and machine learning professionals.

Inhalt: " A boy grows up to make positive change in his community.After suffering much heartache, Sundar decides change must come to his small Indian village. He believes girls should be valued as much as boys and that land should not be needlessly destroyed. Sundar's plan? To celebrate the birth of every girl with the planting of 111 trees. Though many villagers resist at first, Sundar slowly gains their support, and today, over a quarter of a million trees grow in his village. A once barren, deforested landscape has become a fertile, prosperous one where girls can thrive. Sure to plant seeds of hope in children. Improving the world is within everyone's reach."

After he gets married, Sundar works in a marble quarry owned by men who unapologetically wreak ecological havoc on the land. Disgusted by these practices, Sundar quits his job and runs for the position of head of his village, a title known as the sarpanch, and wins. His joy is short-lived: A year after his victory, his oldest daughter dies. As he mourns, he notices how little female children are valued in his village. He then hatches a plan to honor his daughter's memory, change attitudes about gender, and combat the deforestation that has been devastating the local land. Every time a girl is born in the village, Sundar decides that the people will plant 111 trees in her honor. Sundar's idea fundamentally affects his hometown in deeply positive ways. Including endnotes about Rajasthan, gender equity, and eco-feminism, this earnest, inspiring book forthrightly discusses everything from environmental exploitation to female feticide in language suitable for young readers. Although many readers will give a side-eye when Sundar tells the villagers that in developed countries girls and boys are treated equally, overall, this is an uplifting story about the power of personal action.

The notion of planting 111 trees for every baby girl born in his village came to him after a lifetime of struggle and personal tragedy, and this beautiful, poignant book tells of his path from boyhood to village head. Growing up in his Indian village, Sundar cherished time alone with his mother, even when it meant walking miles in the blistering heat to fetch water. As an adult, he taught his children to love and respect nature. And as a worker in the marble mines, he stood his ground when he witnessed the damage being done to the land. Sundar dreamt of planting trees on the ravaged land and, to honor his daughter, ordered the villagers to come around to the idea of planting trees when girls are born. Illustrated in bright, crisp earth tones and textured-leaf motifs, 111 Trees is the true story of radical ideas coming to fruition through collaboration, persistence, and gradual change, an homage to trees, girls, and a planet that is sure to return the favor when we care for it.

The initiative was started in 2006 by the village head, Shyam Sundar Paliwal. Singh's story, written in conjunction with Paliwal, describes his life in the village-of walking with his mother to fetch water and growing up to work in a marble mine that was harming the land. After his young daughter died, Paliwal planted trees in her honor and got the idea to plant trees for all the daughters born in the village to honor them and help the land. Back matter explains more about gender inequality, Paliwal's life, and the initiative, which also includes setting aside money for the girls to use when they turn 18.
