Learning Path
Question & Answer
Choose the Best Answer
Select the features and preprocess the data
Determine the number of neighbors to consider
Use the nearest-neighbor algorithm to classify new data points
Evaluate the model's accuracy and performance
Understanding the Answer
Let's break down why this is correct
First you pick the right measurements and clean the data so the model can learn. Other options are incorrect because People sometimes think you pick the neighbor count before cleaning data, but you need a clean set first; Running the algorithm before deciding how many neighbors to use skips a key decision.
