Question

The K-Nearest Neighbor algorithm (KNN) is a popular supervised machine learning algorithm that can solve both classification and regression problems. One of the most popular software tools used to implement and test k-Nearest neighbor model is python's scikit-learn library. Sklearn is an open source most powerful python's library used to implement machine learning models and statistical modeling. It has simple and efficient tools for data mining and data analysis. It features various classification, regression and clustering algorithms including K-Nearest neighbor, support vector machines random forests and so on. it is built on top of Numpy, SciPy and matplotlib. To implement KNN, we first need to import the necessary libraries like pandas, numpy and matplotlib for data manipulation, computing and visualization then we split the training and testing set to train the model and test its performance. IF the datasets are in different scale, we need to apply feature scaling to bring them in the same scale using StandardScaler class from sklearn. Preprocessing module. Finally, we train the K- NN model on the training set using KNeighborsClassifier class from Sklearn.neighbors module and set the necessary parameters weights, n_neighbors, metri p.
