Euclidean distance

Euclidean distance is the basis of many measures of similarity and is the most important distance metric. You can compute the Euclidean distance in R using the dist() function. In this exercise, you will compute the Euclidean distance between the first 10 records of the MNIST sample data.

The mnist_sample object is loaded for you.

Instructions

100 XP

Show the labels of the first 10 records of mnist_sample.
Compute the Euclidean distance between the first 10 digits. Be careful to remove the true label. Store the results in a variable named distances.
Show the values stored in distances variable in the console.
Plot the numeric matrix of the distances in a heatmap().
