I. Why do I need a second layer? 1. challenges posed by virtualization to data centers The traditional three-tier data center architecture is designed to cope with the service client-server application's vertical large traffic, and enables network administrators to manage the traffic flow. Engineers use Spanning Tree Protocol (STP) in these architectures to optimize the client-to-server path and support connection redundancy. Virtualization fundamentally changes the network architecture of the d

The application and development of L2/L3 Exchange is very active in the field of telecommunication and network technology. According to OSI layering, L2 corresponds to the data link layer, L3 corresponding network layer. In this paper, the second layer of Ethernet protocol and the corresponding third layer of IP protocol Exchange and routing technology are discussed. Application and development of

Reprinted article: Norm Rule in machine learning (i) L0, L1 and L2 norm[Email protected]Http://blog.csdn.net/zouxy09Today we talk about the very frequent problems in machine learning: overfitting and regulation. Let's begin by simply understanding the L0, L1, L2, and kernel norm rules that are commonly used. Finally, we talk about the selection of the rule item parameter. Because of the size of the space he

The transmission gate of the original text: a brief talk on L0,l1,l2 norm and its application Talking about L0,L1,L2 norm and its application In mathematical branches such as linear algebra, function analysis, a norm (Norm) is a function that gives each vector in a vector space (or matrix) in length or size. For a 0 vector, the length of the other is zero. Intuitively, the larger the norm of a vector or mat

L2 norm In addition to the l1 norm, there is also a more favored normalization norm that is L2 norm: | w | 2. It is not inferior to the l1 norm. It has two good terms. In regression, someone calls it ridge regression ), someone calls it "Weight attenuation weight decay ". This is a lot to use, because its powerful effect is a very important problem in improving Machine Learning: overfitting. As for what ove

this validation data is. It is actually used to avoid fitting, and in the course of training, we usually use it to determine some of the parameters (for example, according to the accuracy on validation data to determine the epoch size of the early stopping, according to validation Data determines learning rate, etc.). So why not do this directly on testing data. Because if you do this in testing data, then as the training progresses, our network is actually overfitting our testing data at 1.1 p

Many L2 switches can process packet streams from L2 to L4, which greatly improves the service quality and network security policies of vswitches, the security of the LAN and the internal network of the enterprise becomes the focus. As the most widely used switch in the network, how can we develop its security features to effectively protect network access? Some organizations and vendors have also proposed t

It is used to avoid overfitting, and in the course of training, we usually use it to determine some hyper-parameters (for example, according to the accuracy on validation data to determine the epoch size of early stopping, according to validation Data determines learning rate, etc.). So why not just do this on testing data? Because if we do this in testing data, then as the training progresses, our network is actually overfitting our testing data at 1.1 o ' all, resulting in the testing accura

About L1 Norm and L2 norm of content and diagram, feel has seen times, just read this Daniel blog http://blog.csdn.net/zouxy09/article/details/24971995/, At this moment finally understand that a lost, hurriedly "hot" record!See the difference between L1 norm and L2 norm from two aspects:1. Descent Speed: L1 and L2 are all in a regular way, we add the weight param

Interpreting L2 Ethernet ports and link types with experience L2 Ethernet port Vswitches include Access, Trunk, Hybrid, and QinQ layer-2 Ethernet ports. In this section, the Ethernet ports of the first three L2 switches can be added to a specific VLAN Based on the port VLAN division method. However, only the Hybrid ports can be added to all other VLAN division m

We often use it to determine the number of super-parameters (for example, based on the accuracy on validation data to determine the epoch size of early stopping, validation rate based on learning data, and so on). So why not just do this on testing data? Given these assumptions at testing data, as the training progresses, our network is actually overfitting our testing data at 1.1 points, leading to the final testing accuracy no matter what the reference. Therefore, the training data

So why not just do this on testing data? Because if we do this in testing data, then as the training progresses, our network is actually overfitting our testing data at 1.1 o ' all, resulting in the testing accuracy of the last one having no referential significance. Therefore, the role of training data is to calculate the gradient up

Layer-3 Ethernet switch: introduces L2 VLAN forwarding, configurations in layer-3 Ethernet switches, MAC addresses, and L2 VLAN forwarding, I hope you will have a clear understanding after reading the following articles. The forwarding mechanism of a layer-3 Ethernet switch is divided into two parts: layer-2 forwarding and layer-3 switching. First, let's talk about the second-layer forwarding process. MAC a

L2 switches are still commonly used, so I studied what problems will occur in our lan when the performance of the switches decreases. Here I will share with you, I hope it will be useful to you. One of the following network faults in this article is the failure to withstand the LAN broadcast storm due to poor switch performance, and the cache overflow error, which eventually leads to the failure of the LAN to access the Internet! Considering that the

L1, L2 paradigm and sparse constraintsSuppose that the objective function to be solved is:E (x) = f (x) + R (x)where f (x) is a loss function, used to evaluate the model training loss, it must be arbitrary convex function, R (x) is a normalized constraint factor, used to limit the model, according to the probability distribution of the model parameters, R (x) is generally: L1 paradigm constraints (model obeys Gaussian distribution),
