the previous gradient value (momentum), used to weigh the gradient direction before the current gradient direction of the impact. These two parameters need to be tuning to get the best results, usually based on experience. If you do not know how to set these parameters, you can refer to the relevant papers.In deep learning using SGD, the strategy for better initialization parameters is to set the learning rate to about 0.01 (base_lr:0.01), in the course of training, if the loss start to appear

Suppose the individual income tax is: tax rate * (Salary-1600). Please write a program to calculate the income tax payable, where the tax rate is defined as:
When wages do not exceed 1600, the tax rate is 0;
When the wage is in the interval (1600, 2500), the tax rate is 5%;
When the wage is in the interval (2500, 3500), the tax rate is 10%;
When the wage is in the interval (3500, 4500),

For the connection between the switches, there should be more familiar two kinds: first, is stacked, two, is cascaded. The cascading approach is relatively easy to create bottlenecks between the switches, while stacking technology can increase the backplane rate, can eliminate the bottleneck of the connection between the switches, but by the limitations of distance and so on, and the number of switches is more restrictive. Cisco's switch clustering technology can be seen as a combination of tier

Server Software failure is the highest proportion of server failures, accounting for about 70% of the problem, and the process must be more deliberate. There are many reasons for the software failure of the server, the most common is the server BIOS version is too low, server management software or server drivers have bugs, application conflicts and man-made software failure. The following examples illustrate the maintenance methods of various software failur
