ai4cr

Artificial Intelligence for Crystal (based on https://github.com/SergioFierens/ai4r)

Installation

Add this to your application's shard.yml:

dependencies:
  ai4cr:
    github: drhuffman12/ai4cr

Usage

require "ai4cr"

So far, only Ai4cr::NeuralNetwork::Backpropagation and related tests have been ported.

If you'd like another class of Ai4r ported, feel free to submit a new issue.

Example Spec Results (running on a Lenovo Ideapad y700 w/ i7-6700HQ)

I included the triangle-square-cross training example as test cases.

As expected, the net sometimes correctly guesses all of the examples, more or less, depending on how many times it is trained and various other (random) factors.

Below is an example of the net successfully recognizing all nine test cases.

Setup

$ cd $MY_DEV_FOLDER

$ git clone https://github.com/drhuffman12/ai4cr.git

$ cd ai4cr

$ docker-compose build

These should NEVER fail!

$ docker-compose run app crystal spec --release --no-debug --time --error-trace --no-color
............................

Finished in 184 microseconds
28 examples, 0 failures, 0 errors, 0 pending
Execute: 00:00:00.005837007

These will probably SOMETIMES fail!

$ docker-compose run app crystal spec --release --no-debug --time --error-trace --no-color spec_examples
.............

Finished in 4.1 seconds
13 examples, 0 failures, 0 errors, 0 pending
Execute: 00:00:04.107645264

NOTE: That time, it took less than a second to build. I did notice that it took about 10 seconds to build the first run and only less than a second each successive run.
