Recently, I needed to use iReport to produce PDF reports in a project and encountered many problems, including Detail not displaying, parameter passing problems integrated into Table components in SpringBoot, etc. I found a lot of information on the Internet, all of which were copied and pasted in the same way. Various problems encountered during […]

List the function formulas, function diagrams, advantages and disadvantages and applicable scenarios of four neural network activation functions
1. Step function Step function: This is the simplest non-linear activation function that converts values less than zero to 0 and values greater than zero to 1. Although this function is very simple, it is rarely used because it creates discontinuous jumps between different data, which can lead to non-differentiable situations in the backpropagation algorithm.

11丨Performance script: use cases and diagrams to help you understand the HTTP protocol
Currently the most widely used application layer protocol is HTTP. After thinking about it for a long time, I still think that the HTTP protocol should be written. Because for those who do performance test analysis, the HTTP protocol may be a hurdle that cannot be bypassed. Before talking about HTTP, we need to know […]
