Candidates - Perl5 module for manipulating candidate features (help module for
use Statistics::Candidates; # create a new candidates object and read candidate features $candidates = Statistics::Candidates->new($some_file); # checks for constant candidate features $candidates->check(); # writes candidates that were not added to a file $candidates->write($some_other_file); # clear the administration about being added or not ... $candidates->clear();
Candidates object is for storage, retrieval, and manipulation of candidate features.
The reason for separating this code from
Maxentropy.pm is that a set of candidate features should be considered a separate object. Blessing them into
MaxEntropy would be unnatural.
Also this code is simpler and more stable than that in the
This module requires
$candidates = Statistics::Candidates->new($file);
The syntax of the candidate feature file is more or less the same as that for the events file:
Below is a set of candidates for
c candidate features;
f_ij are bits:
name_c <tab> name_c-1 ... name_2 <tab> name_1 <newline> f_1c ... f_13 f_12 f_11 <newline> . . . f_ic ... f_i3 f_i2 f_i1 <newline> . . . f_mc ... f_m3 f_m2 f_m1
