Setting the Preferences
There are some options possible to be set by the user. They are relative to
gain ratio, prunning and verbosity.
To set the preferences:
- Click Learning > Preferences

- Set the preferences
- Click Ok
The available preferences are:

- Use gain ratio in learning: use gain ratio instead of gain on learning
- Prune the tree: prune the tree generated using the confidence
level set by the user
- Confidence level: confidence level used on the tree prunning, in
percent (enabled if prune the tree is selected)
- Verbosity level: level of detail of the learning data shown by the
Verbosity tab, from 1 to 4
The options are transient: when the user closes UnbMiner, the options
are not maintained.
