With the sustained success of the Spark data processing platform even data scientists with a strong focus on the Python ecosystem can no longer ignore it. Fortunately [...]
A common pattern in most data science projects I participated in is that it’s all fun and games until someone wants to put it into production. From that point in time [...]
Nowadays, Spark surely is one of the most prevalent technologies in the fields of data science and big data. Luckily, even though it is developed in Scala and runs in [...]
The previous two posts gave a short introduction of network anomaly detection in general. We also introduced the k-means algorithm as a simple clustering technique an [...]
Before we actually dive into this topic, imagine the following: You just moved to a new place and the time is ripe for a little house-warming dinner with your best fr [...]
In the previous post we talked about network anomaly detection in general and introduced a clustering approach using the very popular k-means algorithm. In this blog [...]
This blog post shows some results and concepts of a master’s thesis here at inovex. It describes some basic concepts and shows a prototypical architecture for detecti [...]
In the field of machine learning and particularly in supervised learning, correlation is crucial to predict the target variable with the help of the feature variables [...]
Sometimes the analytical power of built-in Hive functions is just not enough. In this case it is possible to write hand-tailored User-Defined Functions (UDFs) for tra [...]
Im Rahmen eines Research-Projektes wurde die Implementierung und Praxistauglichkeit von HyperLogLog auf Apache Spark Streaming mithilfe eines einfachen Prototyps unte [...]
In this final blog post of our 3 part series we will have a look at how you can build your own Apache Mesos framework. If you’re new to Mesos have a look at our [...]
Apache Cassandra is a really impressive piece of technology. When it comes to extreme performance requirements, it is definitely a solution one should look into. Yet [...]
In the previous blog post we described the basics and components of Mesos. Now we want to show you how to run tasks/applications on your Mesos cluster with Marathon, [...]
Another month passed, another retrospex due. This time we’re talking Android embedded, IPv6 for mobile and women in tech – more precisely Sophie Wilson, the cre [...]
Well, turns out that collecting and curating interesting news about technology does not work out on a weekly basis when it is not your main focus. So here we go: inov [...]
