Save learning somewhere

[prostoroman]

Hi, Ivan!
Thank you for great library!
Is there any way to save training results somewhere (file or database) and then only predict based on saved training?

Hi,
There's no way to persist trainings for now.

If you want to save your training you can manually take it from the training object once is returned by the service, in order to build then a new training object with the saved coefficients.

$algorithmCoefficient = $training->getAlgorithmCoefficient();
$normalizationCoefficient = $training->getNormalizationCoefficient();
//persist or whatever...

$training = new Training(
    [], //null data, this is just a reference of which data generated this training, not required
    new GradientDescendent(),
    $algorithmCoefficient,
    new MeanScaleNormalization()
    $normalizationCoefficient,
    new Linear()
);
$training->predict(...);

Good, thank you, I'll try!
