SVM(Support Vector Machines) Classifier

별과 삼각형을 분류하기 위해서 가장 넓은 하늘색 공간(maximum marginal hyperplane(MMH))을 찾는 알고리즘이다. 이 공간을 계산하기 위해 인접한 Support Vectors 라 불리는 데이터 포인트를 이용하게 된다. from sklearn.model_selection import train_test_splitfrom sklearn.preprocessing import StandardScalerfrom sklearn import svmfrom sklearn.metrics import classification_report, confusion_matriximport pandas as pdimport seaborn as snsiris = sns.load_dataset('iris')X_i..

K-Neighbors Classifier

K-Neighbors Classifier란 분류하고자 하는 샘플(Pt)과 가장 가까운 K개의 이웃들 중 가장 많이 속해있는 클래스를 선택하는 분류기이다.만약 k=3으로 하면 별은 보라색원에 속하는 것이고(보라색원 2 > 노란색원 1)만약 k=6으로 하면 별은 노란색원에 속하게 된다   (보라색원 2   아래는 IRIS 데이터셋의 샘플from sklearn.model_selection import train_test_splitfrom sklearn.preprocessing import StandardScalerfrom sklearn.neighbors import KNeighborsClassifierfrom sklearn.metrics import classification_report, confusion_..
