List files by extension - single match (1)

• Download

The create_temporary_directory beanshell creates a temporary directory and outputs the path to that directory. The populate_directory beanshell creates several files within the temporary directory. Once the directory has been populated, it is examined by the List_files_by_extension service and the file path to the one file ending in ".bin" is output.

The create_temporary_directory beanshell creates a temporary directory and outputs the path to that directory. The populate_directory beanshell creates several files within the temporary directory. Once the directory has been populated, it is examined by the List_files_by_extension service and the file paths to the three files ending in ".png" are output.

The create_temporary_directory beanshell creates a temporary directory and outputs the path to that directory. The populate_directory beanshell creates several files within the temporary directory. Once the directory has been populated, it is examined by the List_files_by_extension service. Since no files end in ".fred", an empty list is output.

• Download

Note that this workflow only works on Unix systems. The get_temporary_directory beanshell returns the path to the directory in which temporary files are held. This value is passed to the args port of the execute_cmd_line_app service. The command port of that service has been defaulted to '/bin/ls'. The execute_cmd_line_app service runs the /bin/ls command on the temporary directory. The result is passed to its result port and then to the output port of the workflow.

Concatenate files - multiple files (1)

• Download

The workflow splits the string 'a,b,c,d,e' into its five elements and saves the individual strings to five temporary files. The file paths to those files are then output by the create_and_populate_temporary_file beanshell. The create_temporary_file beanshell creates a file to which the concatentation can be written. The concatenate_files service concatenates the five files and writes the result to the temporary output file. Because the displayresults port has no value, the results are not...

The split_string_into_string_list_by_regular_expresson outputs an empty list since the string to be split is defaulted to ''. As there are no input values, the create_and_populate_temporary_file generates an empty list. The create_temporary_file beanshell creates a file to which the concatentation can be written. The concatenate_files service does not write anything to the temporary output file. Because the displayresults port has been given a default value of 'true', the empty string is ...

Is Parameter Optimization Useful (1)

• Download

This process compares two 10x10fold cross-validations with linear SVM for classification. One use the heuristic parameter choice C=1/avg(K(x,x)) and the other uses an internal 5fold cross-validation to tune the parameter C. Afterwards both performance values are compared via ANOVA and T-test to check whether there is a significant difference between both performance values. The behaviour of the optimized 10x10 XV is similar to that of the experiment 10x10fold_XV_with_optimizedSVM_classificat...

10x10fold_XV_with_optimizedSVM_classification (1)

• Download

This process performs 10 round of 10fold cross-validation for classification with a linear SVM. In each traning-phase the parameters C of the linear SVM is tuned by a 5fold cross-validation. The repetions are useful for estimating the real performance on a small sample high variance data set, e.g. microarray data.

Polygon buffer - Using pyWPS (1)

• Download

Basic example on how to integrate a Web Processing Service (WPS) using  PyWPS's WSDL/SOAP The workflow will accept a GML file with featureCollection where polyon is described using gml:coordinate element structure. This GMl is easely generated with GDAL. The coodinate structure will be converted to WKT and used to create a polygon using shapely, the output will be a buffer polygon with a defined width. Output polygon will replace the orginal polygon and the existing XML will be return...

X-Validation with One-Class SVM (1)

• Download

With this example process, I intend to show how one might validate predictions done with a one class classifier. RapidMiner includes the One-Class SVM (part of libsvm) as introduced by Schoelkopf. I'm very interested in feedback concerning problems with or errors in this experiment. Note that the data set (Sonar) is just a toy data set chosen for demonstration - learning a one class classifier on it won't give you any good results! DESCRIPTION The basic idea is to partition the data set...

Find best feature selection method. (1)

• Download

This processes searches for the best method for feature selection and the best feature subset size. Inside a parameter loop the number of selected features and the feature selection methods are evaluated with a 10fold cross-validation. The Feature Selection Extension ( https://sourceforge.net/projects/rm-featselext ) is required. BUGFIX: Please note that the plugin downloaded before 5th November contains a bug. Due to a bug in RM the TopK-operator sorted the features in the wrong direction. ...

This meta process shows another possibility for automatically optimizing the process layout. The operator "OperatorEnabler" can be used to enable or disable one of its children. Together with one of the parameter optimization operators this can be used to check which operators should be used for optimal results. This is especially useful in order to determine which preprocessing operators should be used for a particular data set - learner combination or if you want to automatically test diffe...
