Now you need to make a foreign currency business, make a purchase order> match the order to generate an invoice> pay,Purchase order exchange rate, invoice exchange rate, payment exchange rate, these exchange rates are a bit dizzyMust the invoice exchange rate be consistent with that of the purchase order ??? My unders

Communication Algorithm 4: Nine debugging methods: theoretical error rate and actual error rate, and nine Error Rate 1. there are nine modulation methods, including BPSK, DBPSK, 2ASK, 2PSK, PSK, opsk, DQPSK, 16QAM, 64QAM, and theoretical error rate formula. You can view the book and use matlab to draw a picture to und

The error rejection rate and false recognition rate are two concepts in image processing. The false rejection rate refers to the error rejection, which refers to intra-class matching. If there are 10 samples of volunteers, each of them has 20 samples. Then, compared with in-class tests, for example, the 20 images in the same category of volunteers on the first da

I have been engaged in Internet advertising for many years. When using Google Analytics tools, concepts such as bounce rate, exit rate, and second hop rate are often seen, but various explanations are often unclear. These indicators are important indicators to measure the user depth (involvement) of the website and help us evaluate the user experience and adverti

In machine learning, supervised learning (supervised learning) by defining a model and estimating the optimal parameters based on the data on the training set. The gradient descent method (Gradient descent) is a parametric optimization algorithm widely used to minimize model errors. The gradient descent method uses multiple iterations and minimizes the cost function in each step to estimate the model's parameters (weights).The pseudo-code for gradient descent is as follows:Repeat the process unt

This article describes how to use the yahoo Exchange Rate Interface to implement real-time exchange rate conversion. For more information, see the following code: The Code is as follows: Function getExchangeRate ($ from_Currency, $ to_Currency){$ Amount = urlencode ($ amount );$ From_Currency = urlencode ($ from_Currency );$ To_Currency = urlencode ($ to_Currency );$ Url = "download.finance.yahoo.com

First, Rate function syntax function function: Returns the interest rate for each period of an annuity. The function rate is calculated by iterative method, and may have no solution or multiple solutions. function syntax: RATE (nper,pmt,pv,fv,type,guess) Parameter introduction: NPer is the total investment period (

Bit rate is the number of digits transmitted per unit time during data transmission. Generally, the unit is kbps, that is, a thousand bits per second. The general understanding is the sampling rate. The larger the sampling rate per unit time, the higher the accuracy. The closer the processed file is to the original file, but the file volume is proportional to the

Which of the following affects the definition of a movie? video bit rate, frame rate, and resolution? Bit Rate: affects the volume, which is proportional to the volume. The larger the bit rate, the larger the volume. The smaller the bit rate, the smaller the volume. Bit

Recently found that many students when they come to consult my questions will talk about a bounce rate, how to reduce the bounce rate and so on, and they simply do not understand what is out of the rate, a lot of people will be out of the rate mistaken for the bounce rate, t

Http://www.cnblogs.com/fengfenggirl/p/classification_evaluate.htmlFirst, IntroductionThere are many classification algorithms, and different classification algorithms use many different variants. Different classification algorithms have different specific, different data sets on the performance of different, we need to choose according to the specific task of the algorithm, how to choose the classification, how to evaluate a classification algorithm, the previous decision tree Introduction, we m

" Difference between compound interest rate and single interest rate : Assume that you have 100 yuan to get the bank deposit period. For high interest rates and three-year deposits, assume that the current three-year periodic interest rate is 5%. The two different results are as follows: Single interest rate: ￥100

Which of the following affects the definition of a movie? video bit rate, frame rate, and resolution? Bit Rate: affects the volume, which is proportional to the volume. The larger the bit rate, the larger the volume. The smaller the bit rate, the smaller the volume. Bit

Using the serial port often see the term baud rate, often based on it to adjust the serial port clock.However, the baud rate is not strictly reflect the serial port transmission rate (clock frequency), in fact, the bit rate can directly reflect the signal transmission rate (

A business channel (TCH) contains coded voice or user data. It can be divided into full-rate business channels (TCH/F) and half-rate business channels (TCH/h, the two messages respectively contain information with a total rate of 22.8 and 11.4 kbit/s. The half rate channel can be obtained by using half of all time slot

accuracy and recall rates are widely used in the field of information retrieval and statistical classification of two measures to evaluate the quality of the results. The accuracy is the ratio of retrieving the number of related documents and the total number of documents retrieved, and the precision of the retrieval system is measured; recall is the ratio of the number of related documents retrieved and the number of related documents in the document library, which is measured by the recall of

1. What is presentation volume, clicks, clickthrough rate In the background of Baidu promotion can see the consumption, average price, click, Show, ClickThrough rate, thousands of display costs and other data, these data is your comprehensive evaluation of the effect of promotion, in-depth promotion of the basis of optimization. When the Netizen searches the query, if your account conforms to the Netizen s

These concepts were known a long time ago, but they are often forgotten because they are not the same as their cognitive habits. So simply to summarize these concepts, and then forget to look for (other articles too verbose, computational methods are also written not clear ...)In addition, I will continue to update some other machine learning related concepts and indicators, that is, convenient for themselves, but also for others. Note: This article will be mixed with positive and negative (+) n

Website Bounce Rate (Bounce rates) is an important index to evaluate the performance of a website, high bounce rate, indicating that the user experience of the site is not good, the user jumped out, on the contrary if the rate is lower, the user experience of the site is good, users can find their own needs of the content. And later he may come back to visit your

Bit Rate and frame rate, what mean?I used to have no contact with the video. I am not very familiar with this aspect of video. Now let's take a look at the bit rate and frame rate issues.Bit rate is the number of digits transmitted per unit time during data transmission. Gen
