Workflow Image Mining with RapidMiner (1)

This is an image mining process using the image mining Web service provided by NHRF within e-Lico. It first uploads a set of images found in a directory, then preprocesses the images and visualizes the result. Furthermore, references to the uploaded images are stored in the local RapidMiner repository so they can later be used for further processing without uploading images a second time.

This process shows how Remeber and Recall operators can be used for passing results from one position to another position in the process, when it's impossible to make a direct connection. This process introduces another advanced RapidMiner technique: The macro handling. We have used the predefined macro a, accessed by %{a}, that gives the apply count of the operator. So we are remembering each application of the models that are generated in the learning subprocess of the Split validation. Af...

This workflow performs LSI text-mining content based recommendation. We use SVD to capture latent semantics between items and words and to obtain low-dimensional representation of items. Latent Semantic Indexing (LSI) takes k greatest singular values and left and right singular vectors to obtain matrix  A_k=U_k * S_k * V_k^T. Items are represented as word-vectors in the original space, where each row in matrix A represents word-vector of particular item. Matrix U_k, on the other hand ...

Sample workflow that exploits background knowledge in the form of links connecting attributes in the different measurement data. The input data is assumed to be labeled and consists of different interconnected biological levels. Additionally a number of files defining links between attributes in the different measurement data are provided. This data was used in the KUP data mining challenge (http://tunedit.org/challenge/ON). Here we focus on two biological levels: protein data measured by ...

Workflow Extended Operations for Nominal Values (1)

Created: 05/10/10 @ 16:41:19

License: Creative Commons Attribution-No Derivative Works 3.0 Unported License

Thumb
This process shows examples for the extended operations for nominal values coming with one of the next RapidMiner updates (5.0.011 or 5.1.000). The operations are performed with the operator "Generate Attributes" and can be used directly within the expressions for the new attributes. The supported functions include Number to String [str(x)], String to Number [parse(text)], Substring [cut(text, start, length)], Concatenation [concat(text1, text2, text3...)], Replace [replace(text, what, by)],...

Workflow Using R to add two columns (1)

Thumb
This process shows a simple R script which adds two columns of a data set with R. Of course this is much simpler by using the operator "Generate Attributes" which is done in parallel, but maybe some of you find this short process helpful in order to get started with R.
