Classroom For those that want to know more about the capabilities of Github Classroom, I recommend you start here. Using RStudio Why do we need this tutorial? Well, Github Classroom already allows an auto-integration with Microsoft MakeCode and Repl.it, but we, as R developers, like RStudio, right? So how to solve this? The current solution uses mybinder.org as the cloud service that will create our RStudio session. If someone finds out ... Read More

Feed: Featured Blog Posts - Data Science Central. Author: Vincent Granville. There is no statistical test that assesses whether a sequence of observations, time series, or residuals in a regression model, exhibits independence or not. Typically, what data scientists do is to look at auto-correlations and see whether they are close enough to zero. If the data follows a Gaussian distribution, then absence of auto-correlations implies independence. Here however, we are dealing with non-Gaussian observations. The setting is similar to testing whether a pseudo-random number generator is random enough, or whether the digits of a number such as π behave in a ... Read More

Feed: AWS Big Data Blog. Data is ubiquitous in businesses today, and the volume and speed of incoming data are constantly increasing. To derive insights from data, it’s essential to deliver it to a data lake or a data store and analyze it. Real-time or near-real-time data delivery can be cost prohibitive, therefore an efficient architecture is key for processing, and becomes more essential with growing data volume and velocity. In this post, we show you how to build a scalable producer and consumer application for Amazon Kinesis Data Streams running on AWS Fargate. Kinesis Data Streams is a fully ... Read More

Feed: AWS Big Data Blog. When deploying data lakes on AWS, you can use multiple AWS accounts to better separate different projects or lines of business. In this post, we see how the AWS Lake Formation cross-account capabilities simplify securing and managing distributed data lakes across multiple accounts through a centralized approach, providing fine-grained access control to the AWS Glue Data Catalog and Amazon Simple Storage Service (Amazon S3) locations. Use case Keeping each business unit’s resources as compute and storage in its own AWS account allows for easier cost allocation and permissions governance. In the other hand, centralizing your ...

Feed: Redis Labs. Author: Martin Forstner. Back in 2019, I wrote about how to create an event store in Redis. I explained that Redis Streams are a good fit for an event store, because they let you store events in an immutable append-only mechanism like a transaction log. Now, with an update of the sample OrderShop application introduced in that blog, I’m going to demonstrate how to use Redis as a message queue, further demonstrating Redis Enterprise’s many use cases beyond caching. A quick look at microservices, infrastructure services, and distributed systems Redis is a great solution for creating infrastructure ... Read More

Feed: Cambridge Intelligence. Author: Dan Williams. We’re excited to announce the release of KronoGraph version 1.0: the first developer toolkit for scalable, interactive, browser-based timeline visualizations.Over 100 JavaScript and React developers in some of the world’s leading security and anti-fraud organizations took part in our hugely successful KronoGraph early access program. With the release of version 1.0, timeline visualization applications built using KronoGraph can now be shipped to customers.No matter what kind of data you’re working with – cell phone records, financial transactions, IT network traffic – there’s always a time dimension. Investigators in a range of use cases need ... Read More

Feed: Neo4j Graph Database Platform. Author: Jocelyn Hoppa. To detect fraud fast, analysts need to see a real-world view of the data. Visualizations help answer the key questions: Who was involved? Where and when did it happen? What assets do they hold? And most importantly, how are each of these details connected? In this blog post, I use Neo4j and the other premium tools in GRANDstack to build a graph and timeline visualization app that drives fraud investigations.Focusing on fraud in Wikipedia articles about 2020 U.S. election presidential candidates, we’ll explore why an anomaly detection platform featuring dedicated timeline analysis ...
