Saves data to a file.
- Examples (ExampleTable)
Attribute-valued data set.
Takes a data set provided at the input channel and saves it to a data file with the specified name. The widget remembers a history of the most recent file names. It can save into tab-delimited and comma-separated files, as well as the C4.5’s format and Weka’s .arrf files.
The widget does not save the data every time it receives a new signal on the input as this would constantly (and, mostly, inadvertently) overwrite the file. Instead the data is saved after a new file name is set or the user pushes Save current data.
The schema below can be used to train the naive Bayesian classifier on the data loaded from a file, use the classifier on data from another file and save the misclassified examples (or the correctly classified, depending on what we select in the Confusion Matrix) into a file.
