| mergecld | Merge a classified data with groups |
| -c1 <groups> | classified data for defining the groups of the classes in <cldata> |
| -c2 <cldata> | classified data to be grouped |
| -cout <trgcldata> | result classified data |
This command merges classes of <cldata> according to the class groups defined in classified data <groups>. In this case, the identifiers in <groups> do not refer to actual data records. Instead, they refer to the classes in <cldata>. Resulting classes are named according to the classes in <groups>.
Example (ex3.1): In the case of SOMs, merging means that data records, which are divided between the neurons, are collected to larger classes. In other words, the indexes of the data records chosen to the neurons belonging to some neuron group are collected to the same class in the classified data <trgcldata>.
