The k-Nearest Neighbors algorithm or kNN uses the entire training dataset as the model. Therefore training the model involves retaining the training dataset. Below is a function named knn_model() that does just this. 1 2 3 # Prepare the kNN model def knn_model(train): return train Making...
Implementing a machine learning algorithm will give you a deep and practical appreciation for how the algorithm works. This knowledge can also help you to internalize the mathematical description of the algorithm by thinking of the vectors and matrices as arrays and the computational intuitions for t...
