ANN - Artificial Neural Network for PHP 5.x
This project realizes a neural network topology called multilayer perceptron for PHP 5.x environments. The source code is based on a work by Eddy Young in 2002. Several improvements and changes on this implementation are done by Thomas Wien in 2007.
Version 1.0 by Eddy Young (2002)
- Initial version
Version 2.0 by Thomas Wien (17.12.2007)
- PHP 5.x support
- PHPDoc documentation
- Momentum support
- Linear / binary output
- ANN_InputValue + ANN_OutputValue classes
- Exceptions
- Threshold function
- Tangens hyperbolicus transfer function
- Several performance issues
- Avoiding array_keys & srand
- Changes in saving and loading network
- Printing network details to browser
- Fixing bug: initializing inputs to all hidden layers
- Fixing bug: training for first hidden layer was skipped
