Feed: R-bloggers. Author: Euthymios Kasvikis. INTRODUCTION The ggvis package is used to make interactive data visualizations. The fact that it combines shiny’s reactive programming model and dplyr’s grammar of data transformation make it a useful tool for data scientists. This package may allows us to implement features like interactivity, but on the other hand every interactive ggvis plot must be connected to a running R session.Before proceeding, please follow our short tutorial.Look at the examples given and try to understand the logic behind them. Then try to solve the exercises below using R and without looking at the answers. Then ... Read More

Feed: Featured Blog Posts - Data Science Central. Author: Jesus Ramos. Data Denialism A common scenario that data analysts in general encounter is what I like to describe as "data denialism". Often, and especially while consulting, an analyst will find that the data tells a different story than what the customer holds to be true. It is also often the case that, when presenting this finding, the customer will outright deny the evidence, asserting that either the data or the analysis must be wrong. For example, it may be that a retailer focused on the low-end market is getting most ... Read More

Feed: Planet big data. Author: Julie Steele. August 17th, 2017 Editor’s note: Welcome to Throwback Thursdays! Every third Thursday of the month, we feature a classic post from the earlier days of our company, gently updated as appropriate. We still find them helpful, and we think you will, too! The original version of this post can be found here. Many enterprises are hoping to systematically drive competitive advantage and operational efficiency by gaining insight from data. For that reason, they may be contemplating — or already well into — a “data lake” effort. These are large, complex efforts, typically focussed ... Read More

Feed: Hortonworks Blog – Hortonworks. Author: Casey Stella. The Motivation Many cybersecurity problems are also big data problems.   What is more and more apparent, though, is that these problems are also problems solved by data science.  The modern cybersecurity practitioner solves cybersecurity problems by making sense of data.  This is firmly within the sweet spot where data science meets big data and reaps rewards.  The Metron team at Hortonworks is keenly aware of this relationship as we are building a cybersecurity platform atop big data infrastructure.  While there are many great platforms to use for dealing with the volume and ...

Feed: CDH – Cloudera Engineering Blog. Author: Justin Kestelyn. This framework based on Apache Flume, Apache Spark Streaming, and Apache Impala (incubating) can detect and report on abnormal bad HTTP requests within seconds.                      Website performance and availability are mission-critical for companies of all types and sizes, not just those with a revenue stream directly tied to the web. Web pages can become unavailable for many reasons, including overburdened backing data stores or content-management systems or a delay in load times of third-party content such as advertisements. In addition to the deterioration of user experience during such incidents, search engines quickly ... Read More

Feed: IBM Big Data & Analytics Hub - All Content; Author: siva-anne; This is final blog in the 3-part series on IBM EventStore. Part 1 introduces IBM EventStore, and part 2 describes details on ingesting event data into IBM EventStore using the scenario of Clickstream analysis for a retail business. In this blog, we will look at analyzing the Clickstream data with IBM EventStore to derive timely insights on interests of retail customers. Typically, ingesting streaming event data, persisting with low latency and analyzing it along with historical event data requires integrating multiple analytic systems. IBM EventStore is purpose built to simplify ... Read More

Feed: Microsoft Azure Blog. Author: Corey Sanders. Most modern applications are built using events – whether it is reacting to changes coming from IoT devices, responding to user clicks on mobile apps, or initiating business processes from customer requests. With the growth of event-based programming, there is an increased focus on serverless platforms, like Azure Functions, a serverless compute engine, and Azure Logic Apps, a serverless workflow orchestration engine. Both services enable you to focus on your application without worrying about any infrastructure, provisioning, or scaling. Today, I am excited to announce that we are making event-based and serverless applications ... Read More

Feed: CDH – Cloudera Engineering Blog. Author: Justin Kestelyn. Thanks to Karthik Vadla, Abhi Basu, and Monica Martinez-Canales of Intel Corp. for the following guest post about using CDH for cost-effective processing/indexing of DICOM (medical) images. Medical imaging has rapidly become the best non-invasive method to evaluate a patient and determine whether a medical condition exists. Imaging is used to assist in the diagnosis of a condition and, in most cases, is the first step of the journey through the modern medical system. Advances in imaging technology has enabled us to gather more detailed, higher-resolution 2D, 3D, 4D, and microscopic ... Read More
