Feed: Featured Blog Posts - Data Science Central. Author: Neeraj. Preface This article is based on Unsupervised Learning algorithm: Hierarchical Clustering. This is the brief illustration with a practical working example of forming unsupervised hierarchical clusters and testing them to assure that you have formed the right clusters. This is a real-life data world example which can be studied and evaluated as data is provided for personal use and practice. There are variations to each topic in data science but there is a brief basic pattern that can be followed to build models. “The Datum” empowers you to have access ... Read More

Feed: R-bloggers. Author: Niklas Junker. Networks are everywhere. We have social networks like Facebook, competitive product networks or various networks in an organisation. Also, for STATWORX it is a common task to unveil hidden structures and clusters in a network and visualize it for our customers.In the past, we used the tool Gephi to visualize our results in network analysis. Impressed by this outstanding pretty and interactive visualization, our idea was to find a way to do visualizations in the same quality directly in R and present it to our customers in an R Shiny app. Our first intention was ...

Feed: Planet MySQL; Author: Continuent; Overview The Skinny In this blog post we will discuss how to use the Tungsten Connector keep-alive feature to ensure long-running MySQL & MariaDB/Percona Server client sessions stay connected in a Tungsten Cluster. Agenda What’s Here? Briefly explore how the Tungsten Connector works Describe the Connector keep-alives – what are they and why do we use them? Discuss why the keep-alive feature is not available in Bridge mode and why Examine how to tune the keep-alive feature in the Tungsten Connector Tungsten Connector: A Primer A Very Brief Summary The Tungsten Connector is an intelligent ...

Feed: R-bloggers. Author: R Views. We were recently presented with a problem where the decision maker wanted to understand how their data would naturally group together. The classic technique of k-means clustering was a natural choice; it’s well known, computationally efficient, and implemented in base R via the kmeans() function.Our problem has a slight wrinkle: the decision maker wished to see the data grouped with (nearly) equal sizes. Now, a ‘true’ statistician would tell the client that the right thing to do from a theoretical perspective was to use native k-means results because some centers can simply have more nearby ...

Feed: All - O'Reilly Media. Author: Mac Slocum. Clapping crowd People from across the cloud native and distributed systems worlds came together in San Jose for the O'Reilly Velocity Conference. Below you'll find links to highlights from the event. Infrastructure first: Because solving complex problems needs more than technology Everett Harper looks at the key practices that are crucial for solving our most critical challenges. From puzzles to products Jessica Kerr argues that most programming careers aren’t about writing software; they’re about changing it. How do we heal? Drawing inspiration from restorative justice practices and her own journey of healing, ... Read More

Feed: Teradata Blog. You probably already know that leading analyst firms have been quoting data lake failure rates of 85% for some time now. You may not be aware that one of those same leading analyst firms are now also forecasting that, by 2020, 30% of data lakes will be built on standard relational DBMS (database management system) technology “at equal or lower cost than Hadoop” because – and I quote - “application performance is superior” and “most data going into data lakes is relational.” Put those two things together and you start to understand why MapR has recently gone to the ...

Feed: AWS Partner Network (APN) Blog. Author: AWS Admin. By Geert Wenes, Partner Solutions Architect at AWSMany high performance computing (HPC) and grid customers with large technical and on-premises computing systems select IBM Spectrum LSF and IBM Spectrum Symphony for policy-driven control and scheduling. Spectrum Symphony schedules tasks very fast: in milliseconds, rather than in seconds for conventional schedulers. It also supports tens of thousands of compute nodes and hundreds of applications on a scalable, shared, and heterogeneous multi-site grid. For you, this translates into better application performance, better throughput, better utilization, and the ability to respond quickly to business ... Read More

Feed: Recent Announcements. You can now use a single reader endpoint to connect to your Redis read replicas. Until today, to easily connect to your read replicas you had to manage multiple endpoints at the application level. The new feature allows you to direct all read traffic to your ElastiCache for Redis cluster through a single, cluster-level endpoint ... Read More

Author: joeleslie. Deploying a relational SQL database hasn’t, historically speaking, been a quick and easy task. However, using Red Hat OpenShift that is no longer true. In fact, it's gotten even easier in the newly released OpenShift 4, which includes its own integrated built-in application marketplace called OperatorHub.In this blog, together we'll walk through deploying the NuoDB container-native SQL database in OpenShift using the NuoDB Operator. Settle in, grab some popcorn or gummy fruit (or whatever snacks you like to watch a good movie with, because this is going to be fun). As a bonus, during the demonstration, we'll also ... Read More
