If you have seen the TV series Silicon Valley, you have probably heard of the Not Hotdog application. In this chapter, we will learn how to build that app. The first part of this chapter will involve collecting the data that we will use for creating a machine learning model that can detect whether or not a photo contains a hot dog.
In the second part of the chapter, we will build an app for iOS and an app for Android, whereby the user can pick a photo in the photo library in order to analyze it to see whether it contains a hot dog. The estimated time for completing this project is 120 minutes.
