=head1 NAME
AI::CRM114 - Wrapper for the statistical data classifier CRM114
=head1 SYNOPSIS
use AI::CRM114;
my $crm = AI::CRM114->new(cmd => '/path/to/crm');
lib/AI/CRM114.pm view on Meta::CPAN
# Classify some text
my $class = $crm->classify(['osb'], ['a.css', 'b.css'], $text);
=head1 DESCRIPTION
The CRM114 Discriminator, is a collection of tools to classify data,
e.g. for use in spam filters. This module is a simple wrapper around
the command line executable. Feedback is very welcome, the interface
is unstable. Use with caution.
=head1 METHODS
AI-Calibrate
view release on metacpan or search on metacpan
lib/AI/Calibrate.pm view on Meta::CPAN
=item B<calibrate>
This is the main calibration function. The calling form is:
my $calibrated = calibrate( $data, $sorted);
$data looks like: C<[ [score, class], [score, class], [score, class]...]>
Each score is a number. Each class is either 0 (negative class) or 1
(positive class).
$sorted is boolean (0 by default) indicating whether the data are already
sorted by score. Unless this is set to 1, calibrate() will sort the data
itself.
Calibrate returns a reference to an ordered list of references:
[ [score, prob], [score, prob], [score, prob] ... ]
lib/AI/Calibrate.pm view on Meta::CPAN
B<score_prob> function, along with a new score, to get a probability.

my($data, $sorted) = @_;
if (DEBUG) {

for my $pair (@$data) {
my($score, $prob) = @$pair;
print "($score, $prob)\n";
}
}
# Copy the data over so PAV can clobber the PROB field
my $new_data = [ map([@$_], @$data) ];
# If not already sorted, sort data decreasing by score
if (!$sorted) {
$new_data = [ sort { $b->[SCORE] <=> $a->[SCORE] } @$new_data ];
}
PAV($new_data);
if (DEBUG) {
print("After PAV, vector is:\n");
print_vector($new_data);
}
my(@result);
my( $last_prob, $last_score);
push(@$new_data, [-1e10, 0]);
for my $pair (@$new_data) {
print "Seeing @$pair\n" if DEBUG;
my($score, $prob) = @$pair;
if (defined($last_prob) and $prob < $last_prob) {
print("Pushing [$last_score, $last_prob]\n") if DEBUG;
push(@result, [$last_score, $last_prob] );

This module exports three functions: calibrate, score_prob and print_mapping.
=head1 BUGS
None known. This implementation is straightforward but inefficient (its time
is O(n^2) in the length of the data series). A linear time algorithm is
known, and in a later version of this module I'll probably implement it.

The L<AI::Embedding> module provides an interface for working with text embeddings using various APIs. It currently supports the L<OpenAI|https://www.openai.com> L<Embeddings API|https://platform.openai.com/docs/guides/embeddings/what-are-embeddings>...
Embeddings allow the meaning of passages of text to be compared for similarity. This is more natural and useful to humans than using traditional keyword based comparisons.
An Embedding is a multi-dimensional vector representing the meaning of a piece of text. The Embedding vector is created by an AI Model. The default model (OpenAI's C<text-embedding-ada-002>) produces a 1536 dimensional vector. The resulting vector...
=head2 Comparator
Embeddings are used to compare similarity of meaning between two passages of text. A typical work case is to store a number of pieces of text (e.g. articles or blogs) in a database and compare each one to some user supplied search text. L<AI::Embed...
Alternatively, the C<comparator> method can be called with one Embedding. The C<comparator> returns a reference to a method that takes a single Embedding to be compared to the Embedding from which the Comparator was created.
When comparing multiple Embeddings to the same Embedding (such as search text) it is faster to use a C<comparator>.
lib/AI/Embedding.pm view on Meta::CPAN
my $csv_embedding = $embedding->embedding('Some text passage', [$verbose]);
Generates an embedding for the given text and returns it as a comma-separated string. The C<embedding> method takes a single parameter, the text to generate the embedding for.
Returns a (rather long) string that can be stored in a C<TEXT> database field.
If the method call fails it sets the L</"error"> message and returns C<undef>. If the optional C<verbose> parameter is true, the complete L<HTTP::Tiny> response object is also returned to aid with debugging issues when using this module.
=head2 raw_embedding
lib/AI/Embedding.pm view on Meta::CPAN
my $test_embedding = $embedding->test_embedding('Some text passage', $dimensions);
Used for testing code without making a chargeable call to the API.
Provides a CSV string of the same size and format as L<embedding> but with meaningless random data.
Returns a random embedding. Both parameters are optional. If a text string is provided, the returned embedding will always be the same random embedding otherwise it will be random and different every time. The C<dimension> parameter controls the n...

critters may be weighed against eachother. It provides a set of
commands which may be used by the critters to do useful things within
its universe (such as make a move in a board game, do a spellcheck,
or request a google search).
Physics engines register themselves with the Physics database (which
is managed by Physics.pm). The arguments they pass to
register_physics() get wrapped up in a hash reference, which is copied
for you whenever you call Physics->new("pluginname"). The "commands"
argument is particularly important: this is where you add special
befunge commands and provide references to callback functions to

Fast Artificial Neural Network Library is a free open source neural
network library, which implements multilayer artificial neural
networks in C with support for both fully connected and sparsely
connected networks. Cross-platform execution in both fixed and
floating point are supported. It includes a framework for easy
handling of training data sets. It is easy to use, versatile, well
documented, and fast. PHP, C++, .NET, Python, Delphi, Octave, Ruby,
Pure Data and Mathematica bindings are available. A reference manual
accompanies the library with examples and recommendations on how to
use the library. A graphical user interface is also available for
the library.

A gene is a sequence of tokens, each a member of some group
of simillar tokens (they can of course all be members of a
single group). This module encodes genes as a string
representing token types, and an array containing the
tokens themselves, this allows for arbitary data to be
stored as a token in a gene.
For instance, a regular expression could be encoded as:
$self = ['ccartm',['a', 'b', '|', '[A-Z]', '\W', '*?'] ]

my @out = AI::Logic::AnswerSet::singleExec("3col.txt","nodes.txt","edges.txt","-nofacts");
my @result = AI::Logic::AnswerSet::getAS(@out);
my @mappedAS = AI::Logic::AnswerSet::mapAS(@result);
The user can set some constraints on the data to be saved in the hashmap, such as predicates, or answer sets, or both.
my @mappedAS = AI::Logic::AnswerSet::mapAS(@result,@predicates,@answerSets);
For instance, think about the 3-colorability problem: imagine to
have the edges in the hashmap, and to print the edges contained in the third answer set
lib/AI/Logic/AnswerSet.pm view on Meta::CPAN
my @res = AI::Logic::AnswerSet::getAS(@output);
my @predicates = ("node","edge");
my @stats = AI::Logic::AnswerSet::statistics(\@res,\@predicates);
In this case the data structure returned is the same as the one returned by C<mapAS()>.
Hence, for each answer set (each element of the array of hashes), the hashmap will appear
like this:
{
node => 6

AI::Logic::AnswerSet::createNewFile($file,"b(3). b(4).");
=head3 addFacts
Quiclky adds facts to a file. Imagine to have some data(representing facts)
stored inside an array; just use this method to put them in a file and give it a name.
AI::Logic::AnswerSet::addFacts("villagers",\@villagers,">","villagersFile.txt");
In the example above, "villagers" will be the name of the facts; C<@villagers> is the array
containing the data; ">" is the file operator(will create a new file, in this case);
"villagersFile.txt" is the filename. The file will contain facts of the form "villagers(X)",
for each "X", appearing in the array C<@villagers>.
