Golang NewCentroidStream Examples

Example #1

File: stream.go Project: wilseypa/rphash-golang

func (this *Stream) AddVectorOnlineStep(vec []float64) *itemset.Centroid {
	c := itemset.NewCentroidStream(vec)
	tmpvar := this.varianceTracker.UpdateVarianceSample(vec)

	if this.variance != tmpvar {
		for _, lsh := range this.lshGroup {
			lsh.UpdateDecoderVariance(tmpvar)
		}
		this.variance = tmpvar
	}

	for _, lsh := range this.lshGroup {
		hash := lsh.LSHHashStream(vec, this.rphashObject.GetNumberOfBlurs())

		for _, h := range hash {
			c.AddID(h)
		}
	}
	return c
}

Example #2
