Method Detail

bucketLength

DoubleParam bucketLength()

The length of each hash bucket, a larger bucket lowers the false negative rate. The number of buckets will be (max L2 norm of input vectors) / bucketLength.

If input vectors are normalized, 1-10 times of pow(numRecords, -1/inputDim) would be a reasonable value

Returns:

(undocumented)

getBucketLength

double getBucketLength()
