Contrasting fastai with Keras
In this section, we'll cover some of the similarities and differences between fastai and Keras. While both frameworks provide high-level APIs for deep learning, there are some significant differences between them in terms of their architecture and approach to the problem, as well as differences between the communities using each. By contrasting these two frameworks, you will get a clearer idea of the strengths of fastai and be better prepared for the detailed examinations of fastai applications that are coming in subsequent chapters.
Getting ready
If you have used Keras recently, then you'll be in good shape to benefit from this section. If you haven't used Keras before, or it's been a while since you've used it, I recommend that you take a brief look at this tutorial so that you have a fresh overview of Keras: https://keras.io/getting_started/intro_to_keras_for_engineers/.
