Public Member Functions | |
| drwnUnsupervisedTransform () | |
| default constructor | |
| drwnUnsupervisedTransform (const drwnUnsupervisedTransform &t) | |
| copy constructor | |
| virtual drwnUnsupervisedTransform * | clone () const =0 |
| returns a copy of the class usually implemented as virtual Foo* clone() { return new Foo(*this); } | |
| virtual double | train (const vector< vector< double > > &features)=0 |
| Estimate the parameters of the features transformation. This function must be implemented in the derived class. | |
| virtual double | train (const vector< vector< double > > &features, const vector< double > &weights) |
| Estimate the parameters of the feature transformation using weighted training examples. | |
| virtual double | train (const vector< vector< double > > &features, const drwnFeatureTransform &xform) |
| Estimate the parameters of the features transformation first applying another transform. The default implementation of this function naively transforms the data and passes the transformed data onto the relevant training code. | |
| virtual double | train (const vector< vector< double > > &features, const vector< double > &weights, const drwnFeatureTransform &xform) |
| Estimate the parameters of the feature transformation using weighted training examples first applying another transform. The default implementation of this function naively transforms the data and passes the transformed data onto the relevant training code. | |
