Just looking through some Stocks and ETFs that are crashing and burning. Airlines and Oil have really taking it on the chin. Speaking of chin, people are self improving themselves and their smiles. I like that. Tech and Health will be the winner coming out of this.
One of my first clients at RapidMiner was Marco. He bought RapidMiner Server from us to build dashboards and do a lot of ETL for his company in Mexico. In fact, I think he was our first Latin American customer. I helped me build the dashboards and troubleshoot problems. We met about three years ago at RapidMiner Wisdom. I didn’t have a lot of time to catch up with him there but we managed to get this picture together (Ingo is in there too). Then he promptly got snowed in and stayed a few days longer in the Big Apple. ...
Just some Text Mining resources in RapidMiner that I found cool, helpful, and interesting. This list will be updated as I find more links. Using NLTK and Text Blob python packages Fix spelling mistakes using Text Blog python package Splitting text into sentences inside RapidMiner Building a dictionary based sentiment model in RapidMiner Text processing customer reviews using the Aylien extension
Recently RapidMiner kicked off a new program called Office Hours. Every Wednesday a product expert will show off something cool they created with RapidMiner. This lasts for about 20 minutes and viewers can ask quesitons via Twitter. I recently did one on Advanced ETL techniques which you can watch here. I’m embedding last week’s Office Hours by our own Dr. Puente, which was fantastic. I really loved how he mashed up RapidMiner, R, and Python in one single workflow! It’s a must watch if you’re looking to use the best of the open source world in one single platform! ...
I was fooling around yesterday with the Random Forest Tree operator in Rapidminer because of this post on Revolution Analytics (great website BTW). I downloaded their data set, imported it into a repository, built a simple process, and sampled a % of the data. I did this all without the programming that R demands. Oh, I even got a nice plot of tree. Now, I'm not knocking R. I have great respect for the language and I dabble in it myself, but if I want fast results (*ahem*, rapid), I turn to Rapidminer ever time.
I'm playing around with the Rapidminer Finance and Economics extension, from Broad Reach Analytics, and I like it. It's a slick and fast way to get financial data into your processes and there are lots of operators that let you get data from Bloomberg, the World Bank, and Yahoo. It would normally take me 30 minutes to an hour to cobble together stock quote data from Yahoo into a spreadsheet, then validate the dates, and import them into Rapidminer. Now, using the extension's operator, it took me 5 minutes. ...
There's a whole new set of text mining tutorial videos currently being produced, and they're not by me! Â 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. Â 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. ...
Call me an old cranky fart but I’m not buying the recent drop off in $VIX as a return to the happy days of market madness, its just too manipulated for me. Ben and the Fed have dumped trillions of dollars into the markets and that’s bound to smooth things over for a while, but ask yourself this: is it sustainable? With unemployment rising and the markets seemingly to have hit a brick wall lately, the answer is NO! ...
I've made some serious headway last week in analyzing NFL football data to model game point spreads. I was able to determine with great accuracy (84%), using backfitting, what team would win a matchup. I did this by building a backpropogation model from 2007-2008 data with about 20 matchups as the prediction set. The only bad thing I discovered was that the point spread prediction was way off. ...
I want to teach my kids how to play Go when they get old enough because I think its a good to get them to think about strategy, patience, and game psychology early on. I found it interesting that a comic book started Go's resurgence in Japan. I wonder what it would take to do so here? Keep an eye for the kid playing the really old man. I found it interesting that this game matches your ability, not your age. ...
