Python KNN **What is KNN?** K-nearest neighbors (KNN) is a simple but powerful supervised machine learning algorithm that can be used for both classification and regression tasks. It works by finding the k most similar data points to a new data point and then using the labels of those data points to predict the label of the new data point. **How does KNN work?** To use KNN, you first need to train the model on a dataset of labeled data points. Once the model is trained, you can then use it to predict the label of a new data point by finding the k most similar data points to the new data point and then using the labels of those data points to predict the label of the new data point. The value of k is a hyperparameter that you can tune to improve the performance of the model Chi tiết tại: https://tricksmmo.com/threads/python-knn.189775/
