RapidMiner Resources advanced videos

After a bit of work. I'm pleased to say I've completed the RapidMiner Resources advanced videos and they'll be available on the RapidMiner Resources site soon.

I maintain meta data about the videos and operators and for fun, I've made a process using this data and a new operator I've discovered called "Transition Graph". This is a candidate for "operators that deserve to be better known" because it allows pretty graphs to be drawn.

The meta data I keep records the main operators each video uses as well as the overall running time of the video and the course which it is classified as. Here's a process that takes this data and allows different graphs to be drawn to show which operators are used in which video as well as which video uses which operator.

A brief note on the names - I've prepended "o" for operator and "v" for video to make things clear.

Here is a graph showing that the "Generate Macro" operator is important in 5 videos

Here is another graph that shows the most important operators used by the video called "Macros".

Here's another that shows which operators are covered by each course and what overlap there is.

The process reads a CSV file (here) to generate these graphics. Of course, as time goes on, I will add new videos so the data in the process is a snapshot as at early October 2014. Nonetheless, please feel free to download the process and data and play around with the results to see the videos I have created and the operators that are covered.

The next videos to do are about text mining...

New videos coming soon

I've created another set of videos. These are slightly more advanced and tend to combine more operators together to tell a story.

Here's a graphic using RapidMiner's advanced plotting capabilities that shows the video names and the main operators explained during the video.

They'll be available on the RapidMinerResources site very soon.

I plan to do some new ones over the next few months and the question is what do I choose?

My current candidate list is.

• Groovy Dark Arts
• Text Processing 
• Web Mining
• Time Series in more detail
• RapidMiner Server

Each would translate to between 10 and 20 videos. 

To help me decide which one I will do next, I'd be happy to get feedback. So please leave a comment and it will certainly help me.

Edit: I took the liberty of doing a mini survey at the RapidMiner World conference. The results are shown here

 I'll take notice of this and give some focus to Text Mining and RapidMiner Server.

RapidMiner Master Certificate and other news

I'm pleased to announce that I've successfully passed the RapidMiner Master Certificate examination.

It took a fair amount of revising and I'm very pleased with the outcome.

I will now be able to devote more time to the next set of RapidMinerResources videos of which these are currently under construction...

• Installing RapidMiner Server
• Loop Parameters Grid
• Pivot
• De-Pivot
• Loop Collection
• Nested Loops

Check back often to get more information about these and what others I am planning.

New video content

I've been busy working with Dr Markus Hofmann to create some brand new RapidMiner videos.

It total there are 43 videos totalling 10 hours. Each one is viewable on demand.

The videos give a detailed worked example for the most important RapidMiner operators as well as some more general ones. We'll be adding more over the coming months.
