NAME

       mlpack_fastmks - fastmks (fast max-kernel search)

SYNOPSIS

        mlpack_fastmks [-h] [-v] [-w double] [-b double] [-d double] [-i string] [-m string] [-k int] [-K string] [-p string] [-N] [-o double] [-M string] [-q string] [-r string] [-s double] [-S] -V

DESCRIPTION

       This  program  will  find  the k maximum kernel of a set of points, using a query set and a reference set
       (which can optionally be the same set). More specifically, for each point in the query set, the k  points
       in  the reference set with maximum kernel evaluations are found. The kernel function used is specified by
       --kernel.

       For example, the following command will calculate, for each point in  ’query.csv',  the  five  points  in
       'reference.csv' with maximum kernel evaluation using the linear kernel. The kernel evaluations are stored
       in 'kernels.csv' and the indices are stored in 'indices.csv'.

       $  fastmks  --k  5  --reference_file  reference.csv  --query_file  query.csv  --indices_file  indices.csv
       --kernels_file kernels.csv --kernel linear

       The output files are organized such that row i and column j in the indices output file corresponds to the
       index of the point in the reference set that has i'th largest kernel evaluation with  the  point  in  the
       query  set  with  index  j.  Row  i  and  column  j  in the kernels output file corresponds to the kernel
       evaluation between those two points.

       This executable performs FastMKS using a cover tree. The base  used  to  build  the  cover  tree  can  be
       specified with the --base option.

OPTIONS

              Degree of polynomial kernel. Default value 2.

       --help (-h)
              Default  help  info.   --indices_file  (-i) [string] File to save indices of kernels into. Default
              value ''.

       --info [string]
              Get help on a specific module or option.  Default value ''.  --input_model_file (-m) [string] File
              containing FastMKS model. Default value ’'.

       --k (-k) [int]
              Number of maximum kernels to find. Default value 0.

       --kernel (-K) [string]
              Kernel  type  to  use: 'linear', 'polynomial', ’cosine', 'gaussian', 'epanechnikov', ’triangular',
              'hyptan'. Default value ’linear'.  --kernels_file (-p) [string] File to save kernels into. Default
              value ''.

       --naive (-N)
              If true, O(n^2) naive mode is used for computation.

       --offset (-o) [double]
              Offset  of  kernel (for polynomial and hyptan kernels). Default value 0.  --output_model_file (-M)
              [string] File to save FastMKS model to. Default value ’'.

       --single (-S)
              If true, single-tree search is used (as opposed to dual-tree search.

       --verbose (-v)
              Display informational messages and the full list of parameters and timers at the end of execution.

       --version (-V)
              Display the version of mlpack.
