It finds CNEs among multiple sequences where k -mers derived from each sequence are clustered using minhash signatures and locality-sensitive hashing. The performance evaluation demonstrated MinCNE to be computationally efficient without compromising the accuracy. The MinCNE source codes are available at...
Minwise hashing has become a standard tool to calculate signatures which allow direct estimation of Jaccard similarities. While very efficient algorithms already exist for the unweighted case, the calculation of signatures for weighted sets is still a time consuming task. BagMinHash is a new algorithm...
