Member Function Documentation

evaluateQuery()

double UniformHBE::evaluateQuery ( VectorXd  query )

protected

Take a biased sample from a hash table via HBE.

Parameters

query

query point

Returns

normalized contribution of the biased sample

MoM()

vector< double > UniformHBE::MoM ( VectorXd  q, int  L, int  m  )

protectedvirtual

Parameters

q	query
L	median of L means
m	means of m samples

Returns

: a vector of L elements, where each element is a sum of m samples

Implements MoMEstimator.
