Some people have asked why I haven't blogged since June. Here is why ... (more…)

Once you've connected your 'things' with the Watson Internet of Things platform, the next question is how to process the received data. In some scenarios the raw data triggers actions immediately, sometimes the data needs to be persisted so that it can be used for historical/descriptive analysis and sometimes the data is used to perform predictive analytics and prescriptive analytics.

The Watson Visual Recognition service is now generally available and a lot of new functionality has been added. The service combines the old beta capabilities plus the Alchemy functionality and the previous Visual Insights service. (more…)

This week I attended DNUG in Hamburg/Germany. DNUG is the German user group for IBM Collaboration Solutions. In the app dev track several sessions covered Bluemix. (more…)

As readers of my blog will know, I want to learn more about machine learning. I've managed to run some samples and I've built my own first little samples. It feels like the next step is to understand more about the different algorithms, for example when to pick which one and how to tune the parameters to achieve the best results. (more…)

Below is a quick overview of samples that demonstrate how to use the machine learning capabilities in Spark on IBM Bluemix. (more…)

At InterConnect IBM previewed a new set of DevOps functionality which is now available as experimental on Bluemix. Via Toolchains IBM tools and third party tools can be used seamlessly together for the development, deployment and management of Bluemix applications. (more…)

Apache Spark comes with a set of machine learning samples. One of those sample is a movie recommendation system which makes personalized recommendations based on a technique called Collaborative Filtering. In this article I describe on a high level how this sample works. (more…)

As I'm trying to learn more about machine learning I spent some time to look for data that I can use. While GitHub is the place to get open source code, there doesn't seem to be a counterpart for open data. Below are a couple of websites that help finding data. (more…)

I'm fascinated by the power of machine learning and I'm trying to learn more about this technology. I've started to look into how to use the machine learning library in Spark. (more…)
