RapidMiner Original Uploader Simon Fischer	RCOMM 2011 Challenge 3: RapidDraw (v1) Created: 02/11/11 @ 17:47:11 License: Creative Commons Attribution-No Derivative Works 3.0 Unported License This is a solution for Challenge 3 of the a live data mining process design competition "Who Wants to be a Data Miner" held at RCOMM 2011 in Dublin. The task was to generate a dataset that looks like a spiral when viewed in an appropriate plotter. This process opens a file with three initial data points and subsequently adds more points to the data set in a loop, using macros to extract data values of the predecessors and a "Generate Attributes" operator to add new data points.

(v1) Created: 02/11/11 @ 17:44:45 License: Creative Commons Attribution-No Derivative Works 3.0 Unported License This is a solution for Challenge 2 of the a live data mining process design competition "Who Wants to be a Data Miner" held at RCOMM 2011 in Dublin. Those of you who loved "You Don't Know Jack" will remember this task: To tell whether a certain word is the name of a vodka or the name of a leader of the Soviet Union. The RapidMiner process was allowed to download data from Wikipedia to make this decision. One input file contains a list of words for which two attributes "Vodka" or "Leader" wi...

As you certainly know, Balbo Baggins is the common ancestor of Balbo and Frodo Baggins. The file opened by the operator "Open Ancestor" contains a table with details about parentship in the Baggins family (insert a breakpoint after read CSV). Each example contains a parent and a child. Of course, the same parent can be contai... Rating: 0.0 / 5 (0 ratings) \| Versions: 1 \| Reviews: 0 \| Comments: 0 \| Citations: 0 Viewed: 33 times \| Downloaded: 11 times This Workflow has no tags!

RapidMiner Original Uploader Simon Fischer	POSTing CSV file to RapidAnalytics Web service - scoring process (v1) Created: 02/11/11 @ 14:55:43 \| Last updated: 02/11/11 @ 14:55:44 License: Creative Commons Attribution-No Derivative Works 3.0 Unported License This is the second demo process used in the RapidAnalytics video on creating Web services. This process is the actual scoring process and used the model generated by the first process. The first input must be a CSV blob in the repository. Once the process is exposed as a Web service in RapidAnalytics, this input will be replaced by the body of the HTTP POST request.

Titled "Who Wants to Be a Data Miner", three challenges were issued to the participants of the conference. In all challenges, participants had to design RapidMiner processes as quickly as possible. This is the original solution I had in mind for Challenge 2: "Fibonacci Numbers". It defines a macro n, recurses by applying itself using an "Embed Process" operator on n-1 and n-2, appends the results (so the length is F(n-1)...

RapidMiner Original Uploader Simon Fischer	Optimizing Discretization (v1) Created: 18/06/10 @ 08:04:32 \| Last updated: 18/06/10 @ 08:04:33 License: Creative Commons Attribution-No Derivative Works 3.0 Unported License This process generates a decision tree on the Iris data set. Before the decision tree is generated, the input attributes are discretised so we only work on nominal attributes. We use a combination of "Select Subprocess" and "Optimize Parameters" to select the best out of five different discretizazion methods independently for each of the attributes. The process shows, that the resulting accuracy heavily depends on the choice of the method. It varies between 64% and 94%.

It combines customer segmentation with direct mailing. It loads some transaction data, aggregates and pivotes the data so it can be used by a clustering to perform a customer segmentation. Then, additional data is joined with the clustered data. First, response/no-response data is joined, and them some additional information about the users is added. Finally, customers are classified into response/no-response classes. The dat...

Here, we use a three base learners inside the stacking operator: decision tree induction, linear regression, and a nearest neighbours classifier. Finally, a Naive Bayes learner is used as a stacking learner which uses the predictions of the preceeding three learners to make a combined prediction.
