that the view is still in the hierarchical structure, but does not display or respond. Clicking it is like it is not in the view, but it is actually there. Hidden is quite commonly used. For example, if a view is not needed on a small screen for the time being, it is hidden first. You can hide a view completely by setting hidden property: @property (nonatomic) BOOL hidden; myview.hidden = YES;//view will not be on screen and will not handle events The hidden overhead is less transparent, but t

One point cloud data is the Stanford Rabbit, do three-dimensional point cloud reconstruction after the person can take a good look, but simply read into the program, as a beginner better, further research is still behind, there is a chance that will continue to upload, for example, Delauny triangular grid division, but also want to further study the snake curve: http://download.csdn.net/detail/u013467442/8847911function Point_cloud ()CLCA=importdata (

Stanford ml Public Lesson Note 15In our last note we talked about PCA (principal component analysis).PCA is a kind of direct dimensionality reduction method. By solving eigenvalues and eigenvectors, and selecting some characteristic vectors with large eigenvalues, the effect of dimensionality reduction is achieved.This paper continues the topic of PCA, which contains an application of PCA--lsi (latent Semantic indexing, implied semantic index) and an

This period of time in learning Stanford iOS 8 teaching video, learning without thinking is idle, so prepare to summarize the video to learn some notes, so that they can deepen their understanding.Now I have learned 6 lessons, from these six lessons, the first section of the lecture is mainly about a calculator demo, and interspersed with a few iOS introduction, as well as the introduction of MVC. The fourth section mainly introduces some swift syntax

Because the study of the major is computer network technology, but in school, and did not learn how much network knowledge, so in order to be worthy of the professional, in 06, when working in the Galaxy education in hit a CCNA class, two weeks of the course, a few hours a day.The result is still not learned, because there is too much theory, too little real exercise.So I bought a book, repeatedly see, the theoretical things finally understand, the following is the final form of notes, I think a

,....} (A is the 1th word in the dictionary and Nip is the No. 35000 Word). So for naive Bayes, it can be expressed as the following matrix (the 1th element of the matrix is 1, and the No. 35000 element is also 1)in the multinomial event model, it is expressed as,. This means that the 1th word of the message is a, and the No. 35000 Word is nip. In this case, if the 3rd word in the message is a, the naive is unchanged, but the representation in the Multinomial event model will be x3=1. This allow

The second lesson of the Stanford iOS Development video was finished tonight, and the professor's homework was done.The professor's assignment is to expand on the existing card game app, so that random colors appear at each flop.In fact, this is very simple, that is, the class written by the Professor class to instantiate, while acquiring the specific contents of the card, that is, the contents attribute.Below I will put the finished app and app class

NSObject object, and the value is anyobject.then int, float, double, bool are all received from the NSNumber Bridge, NSNumber is OC in all about the value of the object, int, float, double these and C language int, float, double is also bridged good, So if the API has a C-language int parameter, it can also accept an int from SwiftOf course, if you are sure what data type you need, you can do type conversion. For example, length is a property of NSString, does not exist in string, it does not e
