How To Get Started

Import

#import "KRHebbian.h"

Sample

KRHebbian *_hebbian     = [KRHebbian sharedAlgorithm];
_hebbian.activeFunction = KRHebbianActiveFunctionBySgn;  // Tanh() for [-1.0, 1.0], Sgn() for (-1, 1)
_hebbian.learningRate   = 1.0f;
_hebbian.maxIteration   = 1;
[_hebbian addPatterns:@[@0.0f, @1.5f, @-2.0f, @1.0f]];   // X1
[_hebbian addPatterns:@[@-1.5f, @-2.0f, @-0.5f, @1.0f]]; // X2
[_hebbian initializeWeights:@[@0.5f, @0.0f, @-1.0f, @1.0f]];

[_hebbian setTrainingIteraion:^(NSInteger iteration, NSArray *outputs, NSArray *weights) {
    NSLog(@"Training %li iteration = %@, outputs = %@", iteration, weights, outputs);
}];

[_hebbian trainingWithCompletion:^(BOOL success, NSArray *outputs, NSArray *weights, NSInteger totalIteration) {
    NSLog(@"Trained %li iteration = %@, outputs = %@", totalIteration, weights, outputs);
    // Start in verifying
    [_hebbian directOutputAtInputs:@[@-0.5f, @-1.0f, @-0.2f, @0.5f] completion:^(NSArray *outputs, NSArray *weights) {
        NSLog(@"Verified weights = %@, outputs = %@", weights, outputs);
    }];
}];
