Algorytmy uczenia maszynowego. Zaawansowane techniki implementacji
Giuseppe Bonaccorso
Imponujący rozwój standardowych algorytmów przy ciągłej obniżce cen sprzętu i udostępnianiu coraz to szybszych komponentów przyczynił się do zrewolucjonizowania wielu gałęzi przemysłu. Obecnie uczenie maszynowe pozwala automatyzować procesy, które do niedawna musiały być zarządzane przez człowieka. Zadania, które jeszcze dekadę temu stanowiły nieprzekraczalną przeszkodę, dziś są wykonywane przez zwykły komputer osobisty. W efekcie dzięki technologii oraz dostępnym wysokopoziomowym otwartym platformom każdy, kto zainteresuje się uczeniem maszynowym, może projektować i wdrażać niezwykle potężne modele. Celem tej książki jest przybliżenie profesjonalistom tajników złożonych algorytmów uczenia maszynowego i zasad ich stosowania w praktyce. Poza praktycznymi informacjami dotyczącymi działania algorytmów i ich wdrożeń znalazły się tu również niezbędne podstawy teoretyczne. Opisano klasyczne modele uczenia nadzorowanego, nienadzorowanego i półnadzorowanego. Wskazano, w jakich sytuacjach okazują się one najbardziej przydatne. Zaprezentowano techniki wydobywania danych za pomocą modeli bayesowskich, algorytmu MCMC, a także dzięki stosowaniu ukrytych modeli Markowa. Omówiono zestaw przydatnych do uczenia maszynowego narzędzi, takich jak biblioteki: scikit-learn, Keras i TensorFlow. Najciekawsze zagadnienia: najważniejsze koncepcje teoretyczne uczenia maszynowego modelowanie probabilistyczne i uczenie hebbowskie zaawansowane koncepcje modeli neuronowych modele generatywne, takie jak splotowe sieci GAN i sieci Wassersteina głębokie sieci przekonań zaawansowane algorytmy: TD(tylda), aktor-krytyk, SARSA i Q-uczenie Uczenie maszynowe - już dziś zaimplementuj rozwiązania przyszłości!

Discover how to perform a complete forensic investigation of large-scale Hadoop clusters using the same tools and techniques employed by forensic experts. This book begins by taking you through the process of forensic investigation and the pitfalls to avoid. It will walk you through Hadoop’s internals and architecture, and you will discover what types of information Hadoop stores and how to access that data. You will learn to identify Big Data evidence using techniques to survey a live system and interview witnesses. After setting up your own Hadoop system, you will collect evidence using techniques such as forensic imaging and application-based extractions. You will analyze Hadoop evidence using advanced tools and techniques to uncover events and statistical information. Finally, data visualization and evidence presentation techniques are covered to help you properly communicate your findings to any audience.
Amazon Fargate Quick Start Guide. Learn how to use AWS Fargate to run containers with ease
Deepak Vohra
Amazon Fargate is new launch type for the Amazon Elastic Container Service (ECS). ECS is an AWS service for Docker container orchestration. Docker is the de facto containerization framework and has revolutionized packaging and deployment of software. The introduction of Fargate has made the ECS platform serverless.The book takes you through how Amazon Fargate runs ECS services composed of tasks and Docker containers and exposes the containers to the user. Fargate has simplified the ECS platform. We will learn how Fargate creates an Elastic Network Interface (ENI) for each task and how auto scaling can be enabled for ECS tasks. You will also learn about using an IAM policy to download Docker images and send logs to CloudWatch. Finally, by the end of this book, you will have learned about how to use ECS CLI to create an ECS cluster and deploy tasks with Docker Compose.

Amazon S3 is one of the most famous and trailblazing cloud object storage services, which is highly scalable, low-latency, and economical. Users only pay for what they use and can store and retrieve any amount of data at any time over the Internet, which attracts Hadoop users who run clusters on EC2.The book starts by showing you how to install several AWS SDKs such as iOS, Java, Node.js, PHP, Python, and Ruby and shows you how to manage objects. Then, you’ll be taught how to use the installed AWS SDKs to develop applications with Amazon S3. Furthermore, you will explore the Amazon S3 pricing model and will learn how to annotate S3 billing with cost allocation tagging. In addition to this, the book covers several practical recipes about how to distribute your content with CloudFront, secure your content with IAM, optimize Amazon S3 performance, and notify S3 events with Lambada.By the end of this book, you will be successfully implementing pro-level practices, techniques, and solutions in Amazon S3.
