promise is a new method proposed by ES6 to solve asynchronous programming problems. 1. Synchronous and asynchronous 1) Synchronization task: Task 2 cannot be executed until task 1 is executed. Synchronization tasks are directly placed in the main thread. 2) Asynchronous task: asynchronous tasks are placed in the event queue. Asynchronous task ...

preface    convolutional neural network has made a breakthrough, and the effect is also very ideal. However, the learning process of convolutional neural network is difficult to explain theoretically, so it has been criticized by many people. Therefore, it is very important to visualize its learning process, and so is the purpose ...
