In this case the output of `predict` depends on the parameter settings.
With access only to `value` and `model` we can't know what to output otherwise.

>
> Currently SVM outputs the raw decision function values when using the predict
> function.
> We should have instead the ability to set a threshold above which examples
> are labeled as positive (1.0) and below negative (-1.0). Then the prediction
> function can be directly used for evaluation.
