This slide is the summarization of the book, "Deep Learning with Python - Chapter 2" by Francois Chollet.
Book PDF is available here (http://faculty.neu.edu.cn/yury/AAI/Textbook/Deep%20Learning%20with%20Python.pdf).
And, the Japanese version is "PythonとKerasによるディープラーニング" (https://amzn.to/2oImjwS).
In this slide, I explain the concepts of the neural network, tensor data, and optimization with a lot of figures.
