ntCard: a streaming algorithm for cardinality estimation in genomics data

Project Description

ntCard is a streaming algorithm for estimating the frequencies of k-mers in genomics datasets. At its core, ntCard uses the ntHash algorithm to efficiently compute hash values for streamed sequences. It then samples the calculated hash values to build a reduced representation multiplicity table describing the sample distribution. Finally, it uses a statistical model to reconstruct the population distribution from the sample distribution.
