AI::Ca...Vector(3pm)

✨ NAME ✨

AI::Categorizer::FeatureVector — bestie, it's literally Features vs. Values 💖

(oh and this lives in the User Contributed Perl Documentation, section 3pm, iykyk 🎀)

🌸 SYNOPSIS 🌸

okay so here's the whole vibe in one glance, no cap:

  my $f1 = new AI::Categorizer::FeatureVector
    (features => {howdy => 2, doody => 3});
  my $f2 = new AI::Categorizer::FeatureVector
    (features => {doody => 1, whopper => 2});

  @names = $f1->names;
  $x = $f1->length;
  $x = $f1->sum;
  $x = $f1->includes('howdy');
  $x = $f1->value('howdy');
  $x = $f1->dot($f2);

  $f3 = $f1->clone;
  $f3 = $f1->intersection($f2);
  $f3 = $f1->add($f2);

  $h = $f1->as_hash;
  $h = $f1->as_boolean_hash;

  $f1->normalize;

like. look at her go. she's doing so much ✨

💅 DESCRIPTION 💅

So this class implements a "feature vector", which is a flat data structure that tells you the values chillin' next to a set of features. 🦋

At its base level, a FeatureVector is usually out here representing the set of words in a document — and the value attached to each feature tells you how many times each word shows up in that document. main character word-count energy fr fr.

But bestie, the values are arbitrary, so they can flex and represent other quantities too. And FeatureVectors can also be combined to represent the features of multiple documents. it's giving versatility. it's giving range. 💖

👑 METHODS 👑

...

that's it. that's the section. the docs said ... and I am NOT about to invent methods that aren't in here, that would be so fake of me 😭💀
