Examples of weka.filters.unsupervised.attribute.Normalize

weka.filters.unsupervised.attribute.Normalize
Normalizes all numeric values in the given dataset (apart from the class attribute, if set). The resulting values are by default in [0,1] for the data used to compute the normalization intervals. But with the scale and translation parameters one can change that, e.g., with scale = 2.0 and translation = -1.0 you get values in the range [-1,+1].
Valid options are:
```
 -unset-class-temporarily Unsets the class index temporarily before the filter is applied to the data. (default: no)
```
```
 -S <num> The scaling factor for the output range. (default: 1.0)
```
```
 -T <num> The translation of the output range. (default: 0.0)
```
