Programming is fun. At least many aspects of programming. What's usually not considered funny is writing documentation and... testing. For the former I agree, but I will show you that the latter can also be fun. Even (or especially) with KNIME, and even more with some of the nice additions to the testing framework in 2.10.

KNIME has made a strong case for openness: deliver a complete platform that’s free and open source; then make money by adding functionality to make that platform easier and more efficient to use. But how does that work in reality? The just-released KNIME version 2.10, complemented with the next-generation commercial extensions to the KNIME Analytics Platform, gives us a taste of what they’re cooking up for us.

PMML, Ensembles and KNIME are three hot topics, each one worthwhile to be used. However, when combined together these three pieces offer an even more powerful approach to data analytics than each one alone. We would like to take the opportunity in this post to tell you more about these three puzzle pieces and, more importantly, about how to put them together.

It is indeed a well-deserved honor that KNIME’s leadership has been re-confirmed in Gartner’s famous ‘Magic Quadrant’ for analytic platforms – thanks in large part to the KNIME customers who acted as references. But is this just another award or an indicator of something much more significant? I think the latter.

The Time Series prediction Problem

Time series prediction requires the prediction of a value at time t, x(t), given its past values, x(t-1), x(t-2), …, x(t-n). How do you implement a model for time series prediction in KNIME? For time series prediction, all you need is a Lag Column node!

For example, I have a time series of daily data x(t) and I want to use the past 3 days x(t-1), x(t-2), x(t-3) to predict the current value x(t). This is an auto-prediction problem. Introducing exogenous variables, like y(t) and z(t), into the prediction model, turns an auto-prediction problem into a multivariate prediction problem. Let’s stick with auto-prediction. What we will build is easily extendible to a multivariate prediction.

Over the past years, KNIME has grown from being an interesting new tool for data analysis to a platform for analytics that embraces openness at its core principle. In contrast to proprietary software vendors, KNIME allows integration from any source or vendor, transparency creating reusable workflows, collaboration both inside and outside of your organization, and agility for quick data exploration. The result is faster, more powerful insight into complex data. You can read more about the five pillars upon which an open analytics platform stands on here. This openness is something we, and many of our users, strongly believe is the future of data analytics.
