Implementing the k-NN algorithm using scikit-learn

In the following section, we will implement the first version of the k-NN algorithm and assess its initial accuracy. When implementing machine learning algorithms using scikit-learn, it is always a good practice to implement algorithms without fine-tuning or optimizing any of the associated parameters first in order to evaluate how well it performs.

In the following section, you will learn how to do the following:

  • Split your data into training and test sets
  • Implement the first version of the algorithm on the data
  • Evaluate the accuracy of your model using a k-NN score

Splitting the data into training and test sets

The idea of training and test sets is fundamental to every...
