Types

type Runtime

type Runtime struct {
	// Runtime of SMOTE, since this module extend the SMOTE method.
	smote.Runtime

	// ClassMinor the minority sample in dataset that we want to
	// oversampling.
	ClassMinor string `json:"ClassMinor"`

	// OutliersFile if its not empty then outliers will be saved in file
	// specified by this option.
	OutliersFile string `json:"OutliersFile"`
	// contains filtered or unexported fields
}

Runtime parameters for input and output.

func New

func New(percentOver, k, classIndex int, classMinor, outliers string) (
	lnsmoteRun *Runtime,
)

New create and return new LnSmote object.

func (*Runtime) Init

func (in *Runtime) Init(dataset tabula.DatasetInterface)

Init will initialize LNSmote runtime by checking input values and set it to default if not set or invalid.

func (*Runtime) Resampling

func (in *Runtime) Resampling(dataset tabula.DatasetInterface) (
	e error,
)

Resampling will run resampling process on dataset and return the synthetic samples.
