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.

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

training. 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

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 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),

L1 and L2 regularization items, also called penalty items, are designed to limit the parameters of the model and prevent the model from going over you and adding an entry after the loss function. L1 is the sum of the absolute values of each parameter of the model L2 is the square sum of each parameter of the model. Difference: L1 tend to produce a small number of features, while o

Layer 2 switching The development of L2 Switch Technology is relatively mature. L2 Switch is a data link layer device that can identify the MAC address information in the data packet and forward it according to the MAC address, the MAC addresses and corresponding ports are recorded in an internal address table. The specific workflow is as follows: (1) When the switch receives a packet from a port, it fir

Leads The regularization item can take a different form. For example, in the regression problem, the loss function is the square loss, and the regularization term can be the L2 norm of the parameter vector: Here, the L2 norm of the parameter vector w is represented. A regularization term can also be a L1 norm of a parameter vector: This represents the L1 norm of the parameter vector W. Definitions of

In DSP algorithm design, we often encounter these two choices, or can they be combined? I haven't figured it out yet. Option 1: Cache Option 2: edma + l2 SRAM On TI's website, we have done a calculation on the vlib calculation of the Canny edge. If pipeline is well designed, option 2 is faster. In fact, it depends on many factors. 1. Data Locality 2. The complexity of processing. The more complicated it is, the more advantageous it seems to be in

GE switches are still commonly used. So I have studied the full performance solution of the mainstream L2 switches with all-optical ports. I would like to share this with you and hope it will be useful to you. Recently, the F-engine S2200F series all-optical ports, 10-Gigabit L2 switches and F-engine S2200G series all-optical ports, which are independently developed by beacon network, were officially introd
