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

Description Dearboy, a goods victualer, now comes to a big problem, and he needs your help. In He sale area there is N shopkeepers (marked from 1 to N) which stocks goods from him. Dearboy have M supply places (marked from 1 to M), each provides K different kinds of goods (marked from 1 to K). Once Shopkeepers order goods, Dearboy should arrange which supply place provide what much amount of goods to shopkeepers to Cut down the total cost of transport

Article Description: 3 big points to be concerned about when asking for a demand. Demand is what operators often do, the recent demand is very tangled, but the environment is forced, and can not say, only here to talk about their views on demand. I think the most important factor when asking for a demand is 3 points: risk, cost, substitute Risk Risk is the primary consideration, and if you don't have one, then you don't have to waste

Minimum editing cost problem:For two strings A and B, we need to insert, delete, and modify a string into B string, define the cost of C0,C1,C2 for three operations, design an efficient algorithm to find the minimum cost of changing a string to B string.Given two strings a and b, and their lengths and three operating costs, return the minimum

First, the application of the backgroundEnterprises in recent years rapid development, scale is also growing, and information transmission and feedback methods are still relatively backward, with the continuous development of information technology, people began to try to use technical means to improve the environment. Enterprise projects continue to increase, and as a senior manager, through the level of escalation through the way although can understand the operation of the project, but often

Split each point into the origin A and pseudo point b,a->b there are two one-way (adjacency table implementation needs to establish a reverse empty edge, and to ensure that the loop cost and 0), a residual capacity of 1, the cost of its own negative value (easy to calculate the shortest path), the other residual capacity +∞, the cost is 0 ( The point is guarantee

Hardware design cost savings experience notes1, these pull the high pull low resistance with the big resistance relationship is not small, choose an integer 5K barThere is no 5K resistance on the market, the closest is 4.99K (accuracy 1%), followed by 5.1K (accuracy 5%), its cost is 20% higher than the accuracy of 4.7K 4 times times and twice times. 20% the resistance value of the precision is only 1, 1.5,

Solution report Question: There are n stores, M providers, and a matrix of K commodities Ideas: The question of creating a graph cannot directly build all the information into a graph, because N and M have a relationship with K. If we build a graph like that, we need to split K into M classes, the K type that each warehouse connects to the warehouse, and then connects to N at a cost, But this is actually not the case. We will find that the relations

Idea: This question mainly refers to the creation of graphs for a long time. It was not judged to be full before, so I read this knowledge point again, then we found that there was a bug when the maximum flow of our minimum fee was full, and it was changed. Figure: start to see the question to know that this question is the largest flow of the minimum cost, and then do it without looking at the explanation. Then I couldn't find the answer to my self-b

within the organization, and the organizational costs will continue to rise. In addition, from the perspective of Chinese folk culture, if you want to make people loyal, you have to pay a lot. What is loyalty? Many things often run out of the way with the boss's ideas. For example, if you have a very creative boss who is worried about many non-standard practices in the early stage of the business, he thinks that the loyalty of financial personnel is very important. He finally came up with a tr

The proliferation of virtual servers eliminates the cost-saving benefits that many IT organizations crave when applying server virtualization, said an IT professional who led the company's virtualization initiative. Boeing computing infrastructure designer Jett Thompson says we are under great pressure to find ways to save money as much as possible. Virtualization has been one of the hottest topics since virtualization has found many of the benefits

0-Background When defining the cost function of logistic regression, it is not able to be like linear regression, otherwise the cost function becomes a non-function, it is difficult to converge to the global optimal. 1-Linear regression cost function: The cost function in linear regression:J (θ) =12m∑i=1m (yi−hθ (xi)

With the rapid development of the Internet, whether it is not Internet enterprises have started a large data collection and analysis, the establishment of their own large database, resulting in the creation of countless data acquisition companies, which is what we call the network crawler, network spider, web crawler in the data collection need to use a large number of proxy IP, So what is the proxy IP to have a cost-effective?Perhaps someone will blu

n most situations, a single cost function is not being sufficient to produce complex vehicle behavior. In the This quiz, we ' d like the You-to-implement one more cost function in C + +. We'll use these-C, functions later in the lesson. The goal with this quiz are to create a cost function that would make the vehicle drive in the fastest possible lane, given Seve

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
