In information theory, mutual information (MI, mutual information) is often used to measure the correlation between two words. Mi (x, y) = log2p (x, y)/P (x) P (y)The larger the MI, the closer the two words are combined.When the relationship between x and y is large, mi (X, Y) is greater than 0; when the relationship between x and y is weak, mi (X, Y) is equal to 0; when MI (x, y) when the value is less than 0, X and Y are called "complementary relati

Measure the test taker's understanding about his or her character. People who speak loudly have a clear character. The speech is not false and the speech is honest. People like this have incredible fortune, both leadership and sense of responsibility. They are trustworthy people.If the speaker is not less angry, or else he is good at strategy. People who like to whisper are careful. They are nervous, have some secret, have a tight mouth, and never r

Measure the test taker's knowledge about Array, foreach, and arrayforeach in PHP. 1. Understand Arrays Arrays in PHP are actually an ordered ing. Ing isValuesAssociatedKeys. For more information, see Array in PHP.net. 2. Example: A general Array Here, I use a simple example and use the graphical method to understand arrays. //1.-----------------------------------$a = array(3 => 'a', 1 => 'b', 2 => 'c');echo var_dump($a); [Note]: use arrows to describ

A = 5b = 4a, B = B, aprint (a, B) # Method 2:It can be understood as the box handling process. C = 10d = 20e = c # define the third person e, and give the box c to e with c = d # give the box d t

Measure the time consumed by functions in Python. This example describes how to count the time consumed by functions in Python. Share it with you for your reference. The specific implementation method is as follows: Import timedef time_me (fn): def _ wrapper (* args, ** kwargs): start = time. clock () fn (* args, ** kwargs) print "% s cost % s second" % (fn. _ name __, time. clock ()-start) return _ wrapper # This decorator can conveniently count th

performance needs through scale-out?On this basis, we tested 20 k8s Vxlan modes and 32 cloud host machines running in tens of millions of RPM scenarios. From the flow of each half to gradually increase the amount of k8s to observe the performance impact, while observing its stability, the results of the next phase of the test revealed.Dear friends. When migrating applications to k8s, Mesos, or native Docker, you can also use the cloud-based tools to test the impact of a schema change on a real

The following small series will provide you with an article on how to count the maximum number of characters in a string [Implementation Code ]. I think this is quite good. I will share it with you and give you a reference. Measure the number of characters that appear the most frequently in a string.

Windows Client development-how to measure the physical length of a string The first thing to note is that the length of the string I mentioned is neither the length of the string nor the size of the string. I mean the display length, that is, the physical length. Reason:This is because of some problems.When duilib is used for development, it is found that the label control cannot adapt to the width. Thoughts:This shows that this library is insufficien

Python is used to measure the frequency of occurrence of words in a text string, This example describes how to calculate the frequency of occurrence of words in a python text string.

In the past few years, there have been more and more harassing calls, mainly because there are too many mobile phone numbers, software registration, express delivery, and then sales promotion of various houses. A long time ago, I thought there was no software that could dynamically bind my own number and number. In this way, when buying a house, you can use a small number to unbind it after use. Le Zai. Also, I am in conflict with my girlfriend, wife, and friends. I guess I won't be rejected if

Tags: pointer typedef C function pointer Function A pointer function returns a pointer to a function, and a pointer to a function! When C is compiled, each function has an entry address, which is the address pointed to by the function pointer. Function pointers have two purposes: to call a function and to make a function parameter (that is, a callback function, the function pointer is passed as a parameter to another function ). (1) first form: Function Type (flag pointer variable name)

a new GNU C keyword, used to get the data type, we do not have to pass in, let typeof directly get!#define max(x, y) ({ typeof(x) _x = (x); typeof(y) _y = (y); (void) (_x == _y); _x > _y ? _x : _y; })In this macro definition, the TypeOf keyword is used to get the two parameter types of a macro. Dry goods in (void) (x = = y), this sentence, is simply a genius design! One is to give users a warning, for different types of pointer comparisons, the compiler will give a warning tha

How can I quickly open the drawing and locate the CAD online? Now many friends know how to use the CAD view software to open the CAD drawings and measure the drawing distance, but some friends do not want to download and install the CAD view software on the computer desktop. Then you can view the image online. How can I open a CAD drawing with an online view? And measure the drawing distance? What should I

When drawing graphics with geometric artboards, we often use equation expressions to draw function images, and in fact we can use geometric artboards to get an expression of images. Taking straight lines as an example, here is how the linear equation of the geometrical artboards is obtained.The following are the steps:Select "Draw"--"define coordinate system" to hide the grid. Use the Point tool and line segment tool to draw an arbitrary triangle ABC in the drawing area.　　Select the point A and
