The document introduces deep learning and provides examples of its applications. It discusses using a neural network to recognize handwritten digits, how cost functions are used to evaluate accuracy, and how gradient descent helps optimize the network. Potential uses of deep learning mentioned include generating text, images, music, code and designs, and personalizing experiences based on user behavior and expressions. The document also lists several datasets and playgrounds for experimenting with deep learning, as well as resources for using it in frontend development.

Small when the network classi鍖es correctly the digit
Large otherwise
