As we all know, indexing can improve retrieval efficiency because of its two-fork tree structure and small footprint, so access speed blocks. Let's calculate a math problem: if a record in a table occupies 1000 bytes on disk, we index one of the 10 bytes of the field, and the record has only 10 bytes of t
likelihood function obtains the maximal value. The following is an example to introduce the idea and method of the maximum likelihood estimation method.
Set a bag of black and white balls. P is the probability of a white ball being randomly touched from the bag, and the value of P is to be estimated.According to the question, we make the overall Xx={1, if get white ball0, if get black ball{Then X obeys 0-1 distribution B (1,p), where P (x=1) =p, P (x=0) =1-p.For the estimation of P, we do
To explain the meaning of the structure in XML schemata and instances, the main theme of this thinking XML column has been to focus on semantic transparency. I've introduced a bottom-up approach to semantic transparency, using this approach to define terms and concepts (the actual index dictionary) in a separate document and Schemata way, and then to apply them extensively. The industry has built a lot of plans for bottom-up semantic transparency, some of which have better viability. In this col

think we have found three different numbers and killed them, the kill process is ntimes [0] And ntimes [1] minus 1. If any of them becomes 0, the corresponding candidate is cleared, here ntimes [1] minus 1 is changed to 0, so candidate [1] is to be cleared, waiting for the next value to come in.
In this way, candidate [0] and candidate [1] are the two water kings we are looking.
To expand the question, you need to find three IDs with more than 1/4 posts. You can follow my ideas.
