Types ¶
type Uniform ¶
type Uniform interface {
Initialize(sampleRange uint64) error
Sample(length int) ([]uint64, error)
Seed(int64)
ClearSeed()
Reset()
Next() (uint64, error)
}
Uniform samples values without replacement in the provided range
func NewBestUniform ¶
NewBestUniform returns a new sampler
type Weighted ¶
type Weighted interface {
Initialize(weights []uint64) error
Sample(sampleValue uint64) (int, error)
}
Weighted defines how to sample a specified valued based on a provided weighted distribution
func NewDeterministicWeighted ¶ added in v1.6.0
func NewDeterministicWeighted() Weighted
type WeightedWithoutReplacement ¶
type WeightedWithoutReplacement interface {
Initialize(weights []uint64) error
Sample(count int) ([]int, error)
Seed(int64)
ClearSeed()
}
WeightedWithoutReplacement defines how to sample weight without replacement. Note that the behavior is to sample the weight without replacement, not the indices. So duplicate indices can be returned.
func NewBestWeightedWithoutReplacement ¶
func NewBestWeightedWithoutReplacement( expectedSampleSize int, ) WeightedWithoutReplacement
NewBestWeightedWithoutReplacement returns a new sampler
func NewDeterministicWeightedWithoutReplacement ¶ added in v1.6.0
func NewDeterministicWeightedWithoutReplacement() WeightedWithoutReplacement
NewWeightedWithoutReplacement returns a new sampler
func NewWeightedWithoutReplacement ¶
func NewWeightedWithoutReplacement() WeightedWithoutReplacement
NewWeightedWithoutReplacement returns a new sampler
