I recently learned the minimum cost maximum flow;I'd like to talk a little about the maximum flow of minimum cost.What is the minimum cost maximum flow?We can think of the minimum cost as the shortest way;Simple!!!That is, an edge has two weights;One for the edge, the other for the flow value;What is the maximum flow?When we find the minimum
to be converted from multimode to Single-Mode Optical Fiber for transmission. If a digital signal is used, it can be easily transmitted. In a single input and output mode, the optical distribution amplifier can be used to configure the conversion without any baseband signal attenuation during the transmission process.
If you have an existing optical fiber installation that needs to be upgraded, consider replacing all the current transmitters and receiving machines with the new digital multiplex

1. Logistic regression
Logistic regression, the output variable range of the model is always between 0 and 1. The assumptions of the logistic regression model are:
g for logical functions (logistic function) is a common logical function for S-shape functions (Sigmoid function), the formula is:
, the image of the function is:
Together, we get the hypothetical model of the logistic regression model:
, the hθ (x) function is that for a given input variable, the probability of the output variable
