This article introduces the relevant knowledge of "how to use tensorflow to build a two-tier CNN network". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Briefly explain the characteristics of CNN:

(1) Local connection (2) weight sharing (3) pooling operation (4) hierarchical structure

The idea of building a network

1. Prepare training data

2. Define the node (placeholder) ready to accept data (placeholder)

3. Define convolution layer

4. Define loss expression

5. Choose the optimizer optimizer to minimize the loss

Steps to perform tensorflow:

(1) construct data flow graph

(2) execute the session

Specific implementation code

All right, I'm going to start!

Preparatory work

1. Prepare training data (use datasets with mnist)

2. Define the node (placeholder) ready to accept data (placeholder)

3. Define convolution layer

4. Define loss expression

5. Choose the optimizer optimizer to minimize the loss

The detailed code is as follows:
