Supervised Learning:

• given a data set
• already know what the correct output is

Transfer Learning:

• model already has knowledge to solve a problem
• now apply it to a different but related problem
• still related to classified images but it is a new defined class

Teachable Machine

• uses transfer learning
• uses MobileNet pre-existing 1000 ImageNet class name ids
• x-axis (1-1000) ImageNet Ids
• y-axis (0-1) probability of each class (confidence level of prediction)
