Iris-setosa:0, Iris-versicolor:1, and Iris-virginica:2. To encode this data map convert each value to a number. Previous: Write a Python program using Scikit-learn to convert Species columns in a numerical column of the iris dataframe. Have another way to solve this solution? Contribute your code (and comments) through Disqus. Knn = KNeighborsClassifier(n_neighbors=7) X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.20) #Split arrays or matrices into train and test subsets Train or fit the data into the model and calculate the accuracy of the model using the K Nearest Neighbor Algorithm.įrom sklearn.neighbors import KNeighborsClassifierįrom sklearn.model_selection import train_test_split Out of total 150 records, the training set will contain 120 records and the test set contains 30 of those records. Write a Python program using Scikit-learn to split the iris dataset into 80% train data and 20% test data. Python Machine learning K Nearest Neighbors: Exercise-5 with Solution
