Graph machine learning (graphML) is a subset of deep learning with much higher accuracy because big data records are linked together by their relationships.
Globalization (G11n) of an application involves more than just translating text. Internationalization (I18n) is the process of enabling your application to be used in different languages and culture. Localization (L10n) covers the work to provide the application in one specific language and culture. Selected locales can help in providing translated text, but some information needs to be converted (times, dates, currencies).
#NLP #MachineLearning #algorithm learns to tell #stories by summarizing #commercial #RealEstate #data, #earning #profits and spurring #CustomerRetention. #BINGO!
When localizing an application, treat the capabilities as features. Consider the specific use cases and work with the users to refine the approach. There may be design and layout adjustments needed per language. If the application is a CMS, content as well as application resources may need translations.

Dave and Ted discuss Graphday and their thoughts on DSE, Neo4j, Microsoft's CosmosDB, and JanusGraph.
In this post, we're going to dive into the client-side single-page application, commonly abbreviated as “SPA”. What is considered an SPA? What are important choices to be made when building one? How do you deploy it? When is an SPA a good choice or a bad choice?
Trying to modernize monolithic legacy applications is hard: these applications are core drivers of the business and the risk of messing them up is too great. However, as time goes on, the cost of maintaining these monoliths grows.
In this blog post, I'll discuss the process of building a micro service that is backed by a graph database and the technologies leveraged to accomplish it. I'll be building this microservice in Java using Maven for its declarative dependency management and build process and Dropwizard for its straightforward architecture and configuration, and then connect everything up to an Apache Tinkerpop enabled Graph Database.
We get asked that question a lot given our early customer work with Titan evaluations, participation in the JanusGraph project and usage of Apache TinkerPop while concurrently being a premier DataStax Graph partner.
DataStax released 5.1, Neo4j released 3.2, Microsoft announces CosmosDB; there’s a lot of stuff happening in the graph database world. Looks like a prime time for some Gremlin training.
Software and web developers often wear many hats, including the UX/UI hat. But some developers lack the knowledge to design UIs or to collaborate effectively with UX designers and researchers.
If you know anything about Expero, you know we specialize in solving “complex problems.” This means we’re not working on your average brochure website or e-commerce app. We’re tackling apps and softwares targeted to niche domains with expert end-users who have very specific needs and goals to solve their very complicated problems.

Web application types include static website, traditional server-side rendering, client-side single-page application, and isomorphic single-page applications.
One of the major hesitations from product stakeholders regarding end-user engagement, specifically user testing, is that they often don’t want anyone to see it till it’s “perfect” or “ready” or “MVP.”
In a previous post, we talked about untangling multiple UI controls so that they could be developed independently, but react to user interaction in a synchronized manner. Let’s posit for a moment updates to a line on one map control should cause re-rendering of a cross-section control associated with that line, but that the two controls are in different browsers, or even on different machines.
Reactive Synchronized UI Components: how I learned to stop worrying and love synchronized maps and cross-sections.
Recently I’ve come across the need to use an ambient logical context that would automatically flow with my program logic as it jumps from thread to thread. The .NET Framework has support for this when you are working with Threads and Tasks. It is not well documented, but it Just Works…mostly.
In the last post, we used ZooKeeper as a service registry. When services started, they registered with ZooKeeper at a pre-agreed place. (/services/{dataset-name}). Clients could list the data servers available and decide which ones to connect to, or request that new ones could be launched. Thanks to ephemeral nodes, servers can crash and their registry entries are automatically deleted. Today we’ll talk about three use cases for watching changes in ZooKeeper.
Zookeeper is a distributed database originally developed as part of the Hadoop project. It’s spawned several imitators: Consul, etcd, and Doozerd (itself a clone of chubby.) A lot of the material out there about Zookeeper describes just how it works, not necessarily what you’d use it for. In this series of posts, we’ll cover how we used it at one client — and it how it also got abused.
It starts innocently enough. You need a database connection string and to know which tables are safe to cache, and there’s just no sense in putting that in your source code. Right? I mean, why put hard-coded stuff in your programming language?
A good development team will already have a battery of tests in place to ensure their code is correct and can be refactored safely.
Especially early in product development, small custom-built datasets are the order of the day.
Most development is feature driven. A developer is on the line to complete a user story or functional requirement, and even if the application gets a little slower, she’d rather have a demo to show during sprint review, instead of watching every one else’s demo.
Every distributed system eventually requires messages to be written on the wire to be transmitted from one machine to another. In many cases these messages are hidden magic. Using WCF web services, or Thrift RPC, code-generated proxies make remote calls look like function calls.
How many times has a customer come and told you your product was “slow”? In this multi-part series, we will discuss how “slow” happens, and how you can fix it.
We were working with a potential client a few weeks ago, trying to figure out if we could help them improve some seismic processing software. The software had excellent science under the covers, but the visual interface was old and tired. Could Palladium help rejuvenate their user experience? Old looking software can imply old or out of date capabilities. Could we make it, well, better?
Implementing this new logic “the declarative way” is an interesting and typical example of how we use Knockout and Rx to capture the logic and business rules in declarative statements that just work and avoid the complex logic you’d need to implement this functionality imperatively.
When writing a complex single page web application, you find yourself dealing with A LOT of asynchronous activities. The user is busy clicking on UI elements and typing in text boxes. Asynchronous requests and responses are flitting back and forth between the server and client. Perhaps you’ve even got asynchronous messages coming from web workers.
Up until recently, Firefox was the only Windows 7 browser which had support for multitouch. In a recent build, Chrome has also added experimental support. Unsurprisingly, they’ve used the same touch model used by mobile safari.
There’s an old standby which tells us that A supercomputer is a device for turning compute-bound problems into I/O-bound problems.
In the kind of programming we do — scientific simulations and decision support — modeling is usually the first task, and often the hardest. Structuring your problem the right way can make all the difference in determining whether future code is graceful or spaghetti-like.
I had an interesting discussion with a coworker while planning a new feature for our current project. We are practicing Domain Driven Design and maintain a strict separation between the GUI and the domain logic. We actually treat them as separate applications.
We are meeting more people who are interested in looking into the world of graph databases. Palladium has executed proofs–of–concept for clients to help them explore this world. In this post we summarize what sorts of questions we feel like a proof of concept project can answer, and how we typically tackle them. For our presentation at Graph Day, we’ll be walking through one in particular, but really there are a variety of answers you may want.
A supernode is a vertex with a large number of edges. In graph theory, these high-degree vertices are known as hubs.
When designing and developing software, it is critical to take into account the limitations of the technology employed, especially hardware—things like computers, boxes and other physical devices. But there’s another aspect to hardware that should be taken into account and is often overlooked: the user.
OrientDB is one of several popular graph data stores on the market today. It provides a multi-model approach with the powerful nature of a graph database and the flexibility of a document data store. If you have decided to build out your multi-tenant application on top of OrientDB, you are in luck as it has several built-in, out-of-the-box methods for handling multi-tenancy.
How do you handle customer #2? You delivered an MVP of some hosted software for customer #1. Your brother-in-law knows a guy who has a similar problem and after a lunch meeting, now you need to add customer #2 to your incubating SaaS tool. Of course customer #1 and customer #2 shouldn’t be able to see each other’s data, but you don’t necessarily want to install and configure everything all over again just because you added another customer.
