Detailed Description

Example of using LSH Forest index for L2 distance.

This program is an example of using LSH Forest index. The LSH used is LSB<GaussianLsh>, so the trees in the forest are binary trees.

The current implementation of LSH Forest doesn't allow read/write index files.

Allowed options:
  -h [ --help ]                   produce help message.
  -c [ -- ] arg (=20)             # points to scan from each tree
  -L [ -- ] arg (=1)              number of trees
  -D [ -- ] arg (=10)             maximal depth of tree
  -W [ -- ] arg (=1)              hash function window size
  -Q [ -- ] arg (=100)            number of queries to use
  -K [ -- ] arg (=50)             number of nearest neighbors to retrieve
  -R [ -- ] arg (=3.40282347e+38) R-NN distance range
  -D [ --data ] arg               dataset path
  -B [ --benchmark ] arg
