)] What is DNS? Domain Name System is the phone book of the whole Internet. It can translate the domain name that can be understood into the IP address that can be understood by the machine, so that Internet users no longer need to directly contact the IP address that is difficult to read and understand. The domain name system is very imp ...

Python orchestration Basics Co programming is a way to realize concurrent programming example Simple reptiles import time def crawl_page(url): print('crawling {}'.format(url)) sleep_time = int(url.split('_')[-1]) time.sleep(sleep_time) print('OK {}'.format(url)) def main(urls): ...

We envision a neural network with two input s, one hidden layer in the middle, three neurons in the hidden layer, and one output. The following is an example:       Before implementing the forward propagation of this neural network, let's add some important knowledge. Initialization of weights w and input We initialize the weight w by g ...

Why is resnet input certain? Because resnet finally has a full connection layer. Because of this full connection layer, the size of the input image must be fixed. What are the limitations of a fixed input size? The original resnet will scale the image to 224 × 224 on the imagenet dataset, but there are some limitations in doing so: (1 ...

Yesterday, I ran yum upgrade on the mini computer centos 7.5, which I just got. After restarting, I found that wifi can't connect to the Internet, so I studied it. First, use the ip addr command to view the list of available network devices. If there is no wifi device, you can only see the lo device and two wired network cards: [root@localhost ...

For image tasks of custom datasets, the general process is generally divided into the following steps: Load data Train-Val-Test Build model Transfer Learning Most of the energy will be spent on data preparation and preprocessing. This paper uses a more general data processing method, and builds a simple model, a deeper resnet ...

Value based and decision based In reinforcement learning, there are two kinds of methods, one is based on value and the other is based on policy The typical representative of the value based algorithm is Q-learning and SARS a, which optimizes the Q function to the best, and then selects the best s ...
