K means clustering

We can predict t-shirt sizing using supervised learning, why to use k-means learning?

Hello @GadhamSrinivas,

We can use K-means when we have no ideas, for example, how large should a L-size be, what size for M and S, and we want to determine that based on our customer’s height and weight. You can find this if you watch the video “K-means algorithm” in course 3 week 1. How would you do it with supervised learning? Other than customer’s height and weight, would you need additional information that K-mean doesn’t?
