The Apriori algorithm described earlier has many drawbacks, such as a large number of full-table scans and large computational natural connections, and is now almost no longer usedThe PFP algorithm is used in the Mahout algorithm library, which is the distributed operation mode of Fpgrowth algorithm, and its internal algorithm structure and FPGROWTH algorithm difference are not very largeSo here's the first introduction to the FPGROWTH algorithm that runs in stand-alone memoryOr use the Apriori

Original: http://www.jb51.net/article/111847.htmWhat is auto-boxing and unpackingAutomatic boxing is that Java automatically converts the original type values into corresponding objects, such as converting an int variable to an integer object, a process called boxing, which translates an integer object into an int type value, which is called unpacking. Because the boxes and unboxing here are automatically non-human for conversion, it is called as automatic packing and unpacking. Primitive type B

In addition, the GTX 1050Ti graphics card market after the listing of 1299 yuan or 1499 yuan, and for gamers, if the balance, the graphics card budget is a bit higher than the CPU, because for the game configuration, more is considered graphics performance, At the same time the game to the graphics card performance requirements than the CPU high.

In microcomputer, also known as microprocessor, all the operation of computer is controlled by CPU, the performance index of CPU directly determines the performance index of microcomputer system, what is the difference between Intel Core i3 and I5CPU?
Intel Core i3 can be seen as a further lite version of the Core i5, and will have a version of the 32NM process version (developed with Code Clarkdale, based on Westmere architecture). The biggest featu

2000 yuan, while the general DIY balance installed, CPU budget, usually lower than the graphics card, because most mainstream games, the video card requirements higher than the CPU.
Therefore, we can draw a conclusion that: GTX 1060 is suitable to match the following 2000 yuan, positioning the high-end CPU, there are many options currently available, preferably recommended as follows:

recommended the model equipped with gt750m independent graphics card to let it disdain other similar game, this machine at the beginning of the listing price is very high, and now finally tend to reason. In Jingdong and Tmall Mall can easily buy, i5 processor +gt750m Independent graphics card +1TB hard disk, there is no obvious weakness, it can be said that Y400 is 5000 yuan within the most interesting model.

If the interviewer asks the difference between integer and INT: it is estimated that most people will only talk about two points. ingeter is the int packaging class, the initial value of int is 0, and the initial value of ingeter is null. But if the interviewer asks whether integer I = 1; int II = 1; I = II is true or false? It is estimated that some people cannot answer the question. If you ask another question, it is estimated that more people will be confused. So I have summarized them and ho

never turn a handle into another object. However, the object itself can be modified. Java does not provide any means to turn an object directly into a constant (however, we can write a class ourselves so that the objects in it have a "constant" effect). This restriction also applies to arrays, which also belong to objects. The following is an example of the final field usage:
