(i) Naive Bayesian polynomial event modelin the previous note, the most basic NB model is called the multivariate Bernoulli event model (multivariate Bernoulli event models, hereinafter referred to as NB-MBEM). The model has several extensions, one

The study of this class, I believe that generally on the statistics or logistics related courses should be known to some students. Although the knowledge involved in class is very basic, it is also very important.Based on the collection of some

This article mainly introduces thinkphp3.2.2 front-end and back-end public class architecture issues, and analyzes in detail the simple call methods of front-end and back-end public classes in the form of instances, which is of great practical value,

This session describes the component Uitextfield in the Uikit framework.Uitextfield (text boxes) and labels look like, but text boxes can be edited. Use the text box in the UI to be aware, because the input text on the emulator can use the computer

We have a info.plist file in our project, we have been in touch with this file since we did the localization setup, there are many settings.You can even view it in XML format, but usually you edit this file by clicking on the project name at the top

There are many queues in iOS, just like the queues in our data structures, where the queue concept is first-in-one. Each method (including closures) is organized in these different queues, and each queue has its own thread to run these queues, which

The last word describes some of the basic principles of view drawing, which continues to unfold. Uibezierpath can draw lots of interesting graphics.Using different constructors, such as Roundedrect, are four rounded rectangles, or simply ellipses

In the previous session, we introduced the knowledge of extensions and protocols, which we introduced a very important concept delegation (proxy), the agent is a very important application of the protocol. Let's review the knowledge of the agent,

Continue with the calculator demo in the last word. The last word is that the class must be initialized. The properties in the class must also be initialized, so you can't just declare without giving it a disposition, so the question is, why is the @

If we are developing a machine learning system and want to try to improve the performance of a machine learning system, how do we decide which path we should choose Next?In order to explain this problem, to predict the price of learning examples. If

Drawing a learning curve is useful, for example, if you want to check your learning algorithm and run normally. Or you want to improve the performance or effect of the algorithm. Then the learning curve is a good tool. The learning curve can judge a
