Intro to graph databases, Part 1: Graph databases and the CRUD operations
If you’re not familiar with graph databases, using one might sound a bit daunting. Anyone who has taken a course on graph theory can probably attest that the subject is a bit complex. But don’t let your graph theory experience (or lack thereof) keep you away from graph databases. In fact, when you use a fully-managed graph database-as-a-service, you get all of the benefits of graph databases without the complexity. This is part one of the two-part tutorial series Intro to Graph Databases.

Introducing command line tools for Watson Visual Recognition
The Watson Visual Recognition service enables you to leverage cognitive computer vision to extract information from any image library. You can even go beyond standard object classification and use what are called ‘custom classifiers’ to train the Watson service to recognize specific items or conditions of your choosing. Read how the Watson Visual Recognition command line interface utility is used to interact with the service to train and test your custom classifiers.

Need a recommendation engine? Graph databases boost customer service with real-time insight
Instead of thinking in terms of business-to-business (B2B) or business-to-consumer (B2C), the new paradigm is business-to-individual (B2I): you must know your customer, and tailor your services to their personal needs and preferences. But how do enterprises enable this paradigm shift in their approach to customer engagement? The answer is a game-changing piece of technology: the recommendation engine.

Predictive Cloud Computing for professional golf and tennis, Part 8: Forecasting
In professional golf and tennis tournaments, athletes welcome any competitive advantage. Looking beyond the current time horizon into the future allows players to position their rackets before the ball arrives and to select the appropriate club based on future weather conditions. The Predictive Cloud Computing project is no different. Time series algorithms project web origin traffic trends into the future so that cloud services can be provisioned or de-provisioned to anticipate sporting content demand. Sinusoidal patterns with a trend, cycle, and level that have been learned from historical data at rest are ensembled together with real-time demand patterns. The combination of InfoSphere Stream, InfoSphere BigInsights, RabbitMQ, WebSphere Java Application, Apache math commons, and custom algorithms have produced forecasts with an 18.44% mean absolute percentage error (MAPE). As a result, provisioning cloud services for future demand loads has saved thousands of compute minutes.
