Beyond Hello World, A Computer Vision Example In the previous exercise you saw how to create a neural network that ¡gured out the problem you were trying to solve. This gave an explicit example of learned behavior. Of course, in that instance, it was a bit of overkill because it would have been easier to write the function Y=2x-1 directly, instead of bothering with using Machine Learning to learn the relationship between X and Y for a ¡xed set of values, and extending that for all values. But what about a scenario where writing rules like that is much more di£cult -- for example a computer vision problem? Let's take a look at a scenario where we can recognize different items of clothing, trained from a dataset containing 10 different types.
