I haven't used JavaScript For a long time, and I feel a little unfamiliar. Recently I am reading some materials about HTML5 mobile development. I have an intuitive idea that JavaScript was very important yesterday and today, tomorrow will be even more important. Many JavaScript-based frameworks have brought great convenience to our development. But to better use these tools, we must have a higher understanding of JavaScript and open up previous notes, start to

method is specified, the system automatically adds an argument-free construction methodWhen there is a specified construction method, no parameter is automatically added to the construction method, no matter whether it is a parameter or no argumentOverloading of constructor methods: multiple methods with the same method name but different parameters, automatically selecting the appropriate method according to different parametersThe construction method can not only assign values to the properti

This is the last article in the expression series from simple to deep, but recently the team has been busy and never been busy! However, if you like expressions, please rest assured that some basic principles of Javascript are common in your work, so I decided to spend some time organizing the basic knowledge and sharing it with you. I was planning to write an article at the beginning, but later I wrote it and found more and more articles. So I decided to write a series. All content in this seri

Latent Dirichlet Allocation (LDA) is a thematic model that enables the modeling of text and the distribution of the subject matter of the document. The commonly used model parameter estimation method has Gibbs sampling and variational inference, there are many introductions about LDA on the net, the most classic such as "Lda math gossip" of Rickjin. The purpose of this paper is to derive the whole process of variational em.Reprint Please specify source: http://blog.csdn.net/u011414416/article/de
