NAME


mlpack_lsh - all k-approximate-nearest-neighbor search with lsh

SYNOPSIS


mlpack_lsh [-h] [-v] [-B int] [-d string] [-H double] [-m string] [-k int] [-n string] [-M string] [-K int] [-q string] [-r string] [-S int] [-s int] [-L int] -V

DESCRIPTION


This program will calculate the k approximate-nearest-neighbors of a set of points using
locality-sensitive hashing. You may specify a separate set of reference points and query
points, or just a reference set which will be used as both the reference and query set.

For example, the following will return 5 neighbors from the data for each point in
'input.csv' and store the distances in 'distances.csv' and the neighbors in the file
'neighbors.csv':

$ lsh -k 5 -r input.csv -d distances.csv -n neighbors.csv

The output files are organized such that row i and column j in the neighbors output file
corresponds to the index of the point in the reference set which is the i'th nearest
neighbor from the point in the query set with index j. Row i and column j in the
distances output file corresponds to the distance between those two points.

Because this is approximate-nearest-neighbors search, results may be different from run to
run. Thus, the --seed option can be specified to set the random seed.

OPTIONS


--bucket_size (-B) [int]
The size of a bucket in the second level hash. Default value 500.
--distances_file (-d) [string] File to output distances into. Default value ’'.

--hash_width (-H) [double]
The hash width for the first-level hashing in the LSH preprocessing. By default,
the LSH class automatically estimates a hash width for its use. Default value 0.

--help (-h)
Default help info.

--info [string]
Get help on a specific module or option. Default value ''. --input_model_file
(-m) [string] File to load LSH model from. (Cannot be specified with
--reference_file.) Default value ’'.

--k (-k) [int]
Number of nearest neighbors to find. Default value 0. --neighbors_file (-n)
[string] File to output neighbors into. Default value ’'. --output_model_file (-M)
[string] File to save LSH model to. Default value ''.

--projections (-K) [int]
The number of hash functions for each table Default value 10.

--query_file (-q) [string]
File containing query points (optional). Default value ''. --reference_file (-r)
[string] File containing the reference dataset. Default value ''.
--second_hash_size (-S) [int] The size of the second level hash table. Default
value 99901.

--seed (-s) [int]
Random seed. If 0, 'std::time(NULL)' is used. Default value 0.

--tables (-L) [int]
The number of hash tables to be used. Default value 30.

--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.
