Sandbox For beginners. Whether you are trying to build dynamic network models or forecast real-world behavior, this book demonstrates how graph algorithms deliver value — from finding vulnerabilities and bottlenecks to detecting communities and improving machine learning predictions. We walk you through hands-on examples of how to use graph algorithms in Apache Spark and Neo4j. We include sample code and tips for over 20 practical graph algorithms that cover importance through centrality, community detection and optimal pathfinding. Read this book to:. Discover how graph algorithms help you leverage the relationships within your data to develop more intelligent solutions and enhance your machine learning models.
The volume of geospatial data increased tremendously. Such data includes but is not limited to weather maps, Internet-of-Things sensors, and geo-tagged social media. Many data-intensive geospatial analytics applications, such as Machine Learning algorithms, highly rely on the underlying data infrastructures such as database management systems DBMS to efficiently manipulate, retrieve and manage data. My research focuses on crafting database systems to accelerate large-scale geospatial data analytics.
Lightning-fast unified analytics engine. Our goal was to design a programming model that supports a much wider class of applications than MapReduce, while maintaining its automatic fault tolerance. In particular, MapReduce is inefficient for multi-pass applications that require low-latency data sharing across multiple parallel operations. These applications are quite common in analytics, and include:.
Apache Spark is an open-source, distributed processing system used for big data workloads. It utilizes in-memory caching, and optimized query execution for fast analytic queries against data of any size. It provides development APIs in Java, Scala, Python and R, and supports code reuse across multiple workloads—batch processing, interactive queries, real-time analytics, machine learning, and graph processing. Apache Spark has become one of the most popular big data distributed processing framework with , meetup members in
