NAME
Algorithm::DimReduction - Dimension Reduction tool that relies on 'Octave'
SYNOPSIS
use Algorithm::DimReduction;
my $matrix = [
[ 1, 2, 3, 4, 5],
[ 6, 7, 8, 9,10],
[11,12,13,14,15],
];
my $reductor = Algorithm::DimReduction->new;
# matrix has been analyzed beforehand
my $result = $reductor->analyze( $matrix );
print Dumper $result->contribution_rate;
# save and load
$reductor->save_analyzed($result);
my $result = $reductor->load_analyzed('save_dir');
# reduce it
my $reduce_to = 3;
my $reduced_matrix = $reductor->reduce( $result, $reduce_to );DESCRIPTION
Algorithm::DimReduction does Dimension Reduction with Singular value decomposition (SVD).
It relies on svd command of 'Octave'.
METHODS
analyze( $matrix )
reduce( $result_of_analyze, $reduce_to )
save_analyzed( $result_of_analyze, $save_dir )
load_analyzed( $save_dir )
