SVD user-based collaborative filtering rec... (1)

• Download

This workflow takes user-item matrix A as a input. Then it calculates reduced SVD decomposition A_k by taking only k greatest singular values and corresponding singular vectors. This worfkflow calculates recommendations and predictions for particular user %{id} from matrix A. Particular row %{id} is taken from original matrix A and replaced with %{id} row in A_k matrix. Predictions are made for %{id} user based on another users A_k. Note: This workflow uses R-script operator with R library ...

Finding wrong links in Linked Open Data wi... (1)

• Download

This simple workflow shows how to detect wrong links in Linked Open Data. It uses operators from the Linked Open Data and the Anomaly Detection extensions. The process first reads a list of links from the EventMedia endpoint, linking to DBpedia, then creates feature vectors for each of those links. Finally, an outlier detection operator is employed to find suspicious links.

Semantic meta-mining workflow that perform... (1)

• Download

Performs a crossvalidation on a data set composed of meta-data of baseline RapidMiner workflows expressed in RDF with the DMOP's ontology terminology for representing processes. Includes discovery of a set of semantic features (patterns) by the Fr-ONT-Qu algorithm (‘workflow patterns’). Through propositionalisation approach those features may be used in an arbitrary (propositional) RapidMiner classification operator.

1. Getting Started: Learn and Store a Model (1)

• Download

This getting started process shows the first step of learning and storing a model. After a model is learned, you can load (Retrieve operator) the model and apply it to a test data set (see 2. Getting Started: Retrieve and Apply Model). The process is NOT concerned with evaluation of the model. This process will not immediately run in RapidMiner because you have to adjust the repository path in the Retrieve operator.
