The TS-SOM Visual Basic demonstration
This demonstration provides an interface to the Tree-Structured Self-Organizing Map (TS-SOM) software described in the
EUREDIT report WP4.5, WP5.5: "A DLL-library for the TS-SOM Based Editing and Imputation Software",
by I Horppu and P Koikkalainen.
The demonstration is used as follows:
- Select the XML data file by using the ListBoxes provided in the upper half of the form.
- Load the data by clicking the "Load Data" button.
- Click on the "Set Options" button, and a dialog with a range of options will appear.
It should be mentioned that TS-SOM parameters that are not mentioned in this dialog take the
default values given in EUREDIT report WP4.5, WP5.5. For instance the maximum number of iterations is
always the default value of 20, and the TS-SOM dimension is always the default value 2.
The available options are as follows:
- Maximum number of iterations: This option sets the maximum number of iterations that is to be used.
- Huber estimation: This option specifies whether Huber estimation is to be used.
- Outlier imputation: This option specifies whether outlier imputation is performed.
- Topology: The following options are available
- Lattice
- Ring
