RapidMiner - the "Apple of Data Science"?

Like many of you, I spent my childhood during the late 1970s / early 1980s which was ra RadioShack TRS-80 Model 1 (source: Wikipedia)a RadioShack TRS-80 Model 1 (source: Wikipedia)eally the beginning of the "PC era" - at least through my eyes.  The first computer I ever saw was the Radio Shack TRS-80 Model 1 which my elementary school bought in 1981 for goodness-knows-what-reason.  My buddy and I placed out of the 4th and 5th grade math curricula in one year and hence, for 5th grade, our "math class" consisted of putting the two of us in front of this TRS-80 for 45 min every day and leaving us to our own devices (pardon the pun).  In a year we taught ourselves BASIC and were able to read/write to a wonderful cassette tape drive.  We had a pretty good swagger going around school due to our BASIC prowess - we knew how to use this machine better than anyone in the building.  Life was good...

Heating a Vermont house with Pi and Pellets Part 3: Getting data from NOAA

It has been three weeks since my last blog entry about "Pi and Pellets".  Why so long?  It's very simple: it's been too warm to burn any pellets!  We were up over 80°F / 27°C last week - hardly the weather to turn on extra heat.  Fortunately it has turned cool again with nature agreeing with the season change.  The leaves are changing finally and the wild turkey have decided to forage before winter...

Heating a Vermont house with Pi and Pellets - Part 2

 

Greetings Community,

 

It is a crisp morning here in Vermont - 44°F / 7°C - so my quest to get optimal heating efficiency has a renewed sense of urgency.  Snow in September is not unheard of around here.

 

I am still in the data collection phase of this project, although some data are already coming in nicely for analysis (see later on in this post).  Bought several more sensors that I plan on adding to this project in addition to room temp and infrared flame...

Heating a Vermont house with Pi and Pellets - Part 1

Greetings Community,

  

As many of you may know, I live in a beautiful place called Vermont where the leaves are gorgeous in the fall, and there is plenty of snow and cold in the winter.  Hence the cost and logistics of heating your house is a frequent topic of conversation up here and, as an avid data geek, I am always striving to get the maximum BTUs out of my heating system.  In this series of blog posts, I am going to share my new journey of turning my heating system into a wicked-amazing IoT optimization system using a Raspberry Pi, a bunch of sensors, and of course RapidMiner to do the heavy lifting...

Reading Excel files directly from your companies OneDrive

Nowadays many corporate Excel files tend to be online. This seems quite natural, when you consider the wide range of benefits: ease of sharing and collaboration, access from any pc with Internet connection, user right management and constant backups, just to name a few. Wouldn't it be great to include data from those files directly into your Data Mining process, even without downloading the whole file? Now you can! Introducing the new Read Excel Online Operator. It is part of the latest update of the Spreadsheet Table Extraction extension (download link).

Connect to any document within your SharePoint

Companies and organizations often store and share information via Microsoft SharePoint Sites. They are a great way of collecting and sharing information around a given topic. Many sites therefore contain lots of office documents and files in other formats. Integrating these information into a Data Mining process often involves manual searching through sites and folders as well as downloading files by hand. This isn't fast, nor simple. Therefore we created the SharePoint Connector extension to speed things up. You can download it through the RapidMiner Marketplace. It consists of the List SharePoint Files operator, that creates a list of all available files and folders and the Download from SharePoint Operator which downloads files of interest.

Why your Models need Maintenance

People often think a given model can just be put into deployment forever. In fact, the opposite is true. You need to maintain your models like you maintain a machine. Machine Learning models can get off or broken overtime. This sounds odd to you because they have no moving pieces? Well, you might want to have a close look on change and drifts of concept.
