Pull request overview
This pull request converts neural network layers and optimizers to use the NumPower library for numerical operations. The changes include implementing new optimizer classes (StepDecay, RMSProp, Momentum, Cyclical, Adam, AdaMax, AdaGrad), new layer implementations (Swish, Placeholder1D, PReLU, Noise, Multiclass, Dropout, Dense, Continuous, Binary, BatchNorm, Activation), updating tests to use PHPUnit attributes, and reorganizing code into namespaced subdirectories with corresponding documentation updates.
Key Changes
- Migration from tensor library to NumPower for all neural network operations
- Reorganization of optimizers and layers into subdirectory namespaces (e.g.,
Adam/Adam.phpinstead ofAdam.php) - Conversion of PHPUnit test annotations to attributes (
#[Test],#[TestDox], etc.)
