Record Class ADASYN.Options

java.lang.Object
java.lang.Record
smile.classification.resampling.ADASYN.Options
Record Components:
k - the number of nearest neighbors used to compute the local density ratio (typically 5).
ratio - controls the desired level of synthetic data generation. The total number of synthetic samples is G = (|majority| - |minority|) * ratio. A value of 1.0 attempts full balancing. Must be in (0, 1].
highDimThreshold - the dimensionality threshold above which RandomProjectionForest is used instead of KDTree for k-NN search.
rpfNumTrees - number of trees in the RandomProjectionForest.
rpfLeafSize - maximum leaf size for the RandomProjectionForest.
Enclosing class:
ADASYN
public static record ADASYN.Options(int k, double ratio, int highDimThreshold, int rpfNumTrees, int rpfLeafSize) extends Record
ADASYN hyperparameters.
