Working on my RCOMM presentation

I’ve been busy working on my presentation for the first Rapidminer Community Meeting and Conference (RCOMM 2010).  If you find yourself in Dortmund, Germany on September 15th, please stop by to hear me speak!  Of course, there are tons of other reasons to go to RCOMM 2010 and here are just a few that I find interesting:


Pattern Recognition Engineering
Shafait, Reif, Kofler, Breuel; DFKI Kaiserslautern and Technical University Kaiserslautern

Collaborative Work with RapidMiner and RapidAnalytics
Dr. Simon Fischer; Rapid-I

Integrating R into RapidMiner*
Sebastian Land; Rapid-I

Training Sessions

  1. RapidMiner and RapidAnalytics Overview
  2. Training Time Series Analysis and Forecasting
  3. Text Mining with RapidMiner
  4. Market Basket Analysis and Recommender Systems
  5. Data Mining with RapidMiner
  6. Data Preprocessing and Meta Data Propagation

*I’m really looking forward to the unveiling and integration of R into Rapidminer 5.X and I’ll be listening closely to Sebastian’s presentation.

See you in Germany!


A Not So Simple GOOG Chart

What I am about to post is a simple $GOOG chart created by a python script that I grabbed off Trainee Trader’s site.  While creating a line chart of GOOGs stock price is really basic finance, it does represent something very important to me.  It means that I’m learning and troubleshooting python at a fast pace.

I just started learning python about a week ago with absolutely no knowledge in programming (except for Frotran 77 a long time ago), but I am armed with an engineer’s logic and enthusiam. I’ve worked on about 15 exercises in a training course I’m taking, and have read up on all the neat things python can do.   I installed python 2.6, matplotlib, and the ystockquote module from Cory Golberg on my development machine and configured the correct paths.  Then I then tried to copy and paste TTs google chart python script to see if I could recreate his chart.  I typed it verbatim and fired it up in python hoping to see the chart!

Instead of seeing a nice GOOG chart, it crashed on me!!! Yep, it failed and I had no idea what the error messages were telling me.

Fast forward one week and I’m picking up this language quick.  So I took TTs code again, checked out the  documentation  for the matplotlib module, troubleshot it, and got the damn thing to plot!  Go me!

Of course a sophisticated programmer would laugh at my silly plot, but to me it’s awesomeness.

Update: Here’s the revised python script (txt): GOOGChart2.txt


Rapidminer Text Mining Videos

There’s a whole new set of text mining tutorial videos currently being produced, and they’re not by me!  Neil over at Vancouver Data Blog is rolling out 5 brand new tutorial videos over the course of the week on how to use Rapidminer for text mining.  His first video on how to load text in Rapidminer is a great way for novice text miners to get started and learn how to wield unstructured data.

I’m definately checking out his posts this week, especially the ones toward Friday because they intersect with what I’m doing with my Twitter project, and you should too!
