## Detailed Description

### template<class LabelType = double>
class vigra::ProblemSpec< LabelType >

problem specification class for the random forest.

This class contains all the problem specific parameters the random forest needs for learning. Specification of an instance of this class is optional as all necessary fields will be computed prior to learning if not specified.

if needed usage is similar to that of RandomForestOptions

## Member Function Documentation

ProblemSpec& classes_ | ( | C_Iter | begin,
|  | C_Iter | end
| ) |  |

supply with class labels -

the preprocessor will not calculate the labels needed in this case.

ProblemSpec& class_weights | ( | W_Iter | begin,
|  | W_Iter | end
| ) |  |

supply with class weights -

this is the only case where you would really have to create a ProblemSpec object.
