ios-KRFuzzyCMeans-Algorithm

KRFuzzyCMeans has implemented Fuzzy C-Means (FCM) the fuzzy (ファジー理論) clustering / classification algorithm (クラスタリング分類) on Machine Learning (マシンラーニング). It could be used in data mining (データマイニング) and image compression (画像圧縮). If you wanna know how to use and the details, you could contact me via email.

How to use

#import "KRFuzzyCMeans.h"

- (void)viewDidLoad 
{
    [super viewDidLoad];
    
    KRFuzzyCMeans *_krFcm   = [KRFuzzyCMeans sharedFCM];
    _krFcm.m                = 3;
    _krFcm.convergenceError = 0.001f;
    [_krFcm addCentralX:5.0f y:5.0f];     //The center 1, cluster 1 start in here
    [_krFcm addCentralX:10.0f y:10.0f];   //The center 2, cluster 2 start in here
    [_krFcm addCentralX:12.0f y:14.0f];   //The center 3, cluster 3 start in here
    [_krFcm addPatterns:@[@[@2, @12], @[@4, @9], @[@7, @13], @[@11, @5], @[@12, @7], @[@14, @4]]];
    [_krFcm clusterWithCompletion:^(BOOL success, NSArray *clusters, NSArray *centrals, NSInteger totalTimes)
    {
        NSLog(@"\n\n===============================================\n\n");
        NSLog(@"totalTimes : %li", totalTimes);
        NSLog(@"results : %@", clusters);
        NSLog(@"centrals : %@", centrals);
        NSLog(@"\n\n===============================================\n\n");
        
        //Start in verify and classify others pattern.
        
        //If you don't want to adjust the central groups, just wanna directly classify them, you could use :
        [_krFcm directClusterPatterns:@[@[@2, @3], @[@3, @3], @[@5, @9]]];
        [_krFcm printResults];
        
        //If you have one or more patterns need to do standard classification, use this to renew all groups and re-adjust the central groups :
        [_krFcm addPatterns:@[@[@2, @3], @[@3, @3], @[@5, @9]]];
        [_krFcm clusterWithCompletion:^(BOOL success, NSArray *clusters, NSArray *centrals, NSInteger totalTimes)
        {
            [_krFcm printResults];
            //... Do your next step.
        }];
        
    } eachGeneration:^(NSInteger times, NSArray *clusters, NSArray *centrals)
    {
        NSLog(@"times : %li", times);
        NSLog(@"clusters : %@", clusters);
        NSLog(@"centrals : %@", centrals);
    }];
