Verbose#
Verbose objects are capable of logging important events to any PSR-3 compatible logger such as Monolog, Analog, or the included Screen Logger. Logging is especially useful for monitoring the progress of the underlying learning algorithm in real-time.
Set the Logger#
To set the logger pass in any PSR-3 compatible logger instance:
public setLogger(LoggerInterface $logger) : void
Return the Logger#
Return the logger or null if not set:
public logger() : ?LoggerInterface
use Rubix\ML\Regressors\Adaline;
use Rubix\ML\Loggers\Screen;
$estimator = new Adaline();
$estimator->setLogger(new Screen('example'));
$estimator->train($dataset);
