MySql infinite classification data structure -- pre-sorting traversal tree algorithm bitsCN.com Unlimited classification is a very common application in our development, such as Forum Sections, CMS categories, and many applications.The most common and simple method is ID, parentID, and name in MySql. The advantage is that the structure is simple. The disadvantage

.7 Class Models:like 6 but does not display the fitted Class.8 class models:the probability of the fitted class.9 Class models:the probabilities times the fraction of observations in the node (the probability relative to all Observat Ions, sum across all leaves is 1).BranchControls The shape of the branch lines. Specify a value between 0 (V shaped branches) and 1 (square shouldered branches). Default is if (fallen.leaves) 1 else. 2.Branch=0Branch=1Digits:The number of significant digits in displ

Logical regression (logistic regression, (LR) is a very common classification algorithm in machine learning, which has been widely used in the field of the Internet, whether it is in the advertising system for CTR estimation, the recommended conversion rate in the system, the identification of garbage content in the anti-spam system ... can see its figure. LR is favored by the majority of users for its simple principle and application universality. In

We know that many open source software's infinite classification is the recursive algorithm, but we know that recursion is a waste of time, but also a waste of space (memory), Last time I also shared a my own original infinite classification spanning tree method, a enthusiastic php expert netizens gave me a valuable advice, I tested it, this code of time very short reference: http://www.oschina.net/code/sni

Php unlimited classification tree data formatting code, php tree We know that the infinite classification of many open-source software uses recursive algorithms, but we know that recursion is a waste of time and space (memory ),Last time I also shared my original method of generating tree with unlimited categories. A enthusiastic php expert gave me valuable sugge

Page burying PointPage embedding is to understand the user's view of the application of each page, so as to know the number of page views, user Use path, length of use and so on. Mainly includes the application homepage, the Personal Center page, each level page, each two level page and so on, the principle is that as long as the application renders in front of the screen needs the corresponding buried point, so as to be more accurate calculation application use time, simultaneously can evaluat

Data classification based on BP Neural network BP (back propagation) network is the 1986 by the Rumelhart and McCelland, led by the team of scientists, is an error inverse propagation algorithm training Multilayer Feedforward Network, is currently the most widely used neural network model. The BP network can learn and store a large number of input-output pattern mapping relationships without revealing the m
